Small Dog
New chip to boost appeal of Wi-Fi Texas Instruments says tiny processor extends battery life - The chip, dubbed TNETW1100B, connects users to a network using Wi-Fi technology, a wireless networking standard also known as 802.11b. The technology has been gaining popularity, especially for home networking. Airports, hotels and cafes such as Starbucks have also latched onto the Wi-Fi bandwagon, offering the service in public places so laptop users can connect wirelessly to the Internet

IBM building 64-bit PowerPC chip for Linux? Evidence points to AltiVec support - One of our more astute and busy Architosh readers has written in with information regarding a 64-bit PowerPC chip by IBM which supports AltiVec. While unconfirmed, the nature of the AltiVec support appears to be related to IBM's Linux initiatives

Apple's x86 OS named, sized - Marklar most likely doesn't signal a strategy shift, it simply remains prudent business sense: it helps to have a Plan B, if only to use as a bargaining counter. Think of it as Mutually Assured Destruction

Apple Keeps x86 Torch Lit with 'Marklar' - As Apple Computer Inc. draws up its game plan for the CPUs that will power its future generations of Mac hardware, the company is holding an ace in the hole: a feature-complete version of Mac OS X running atop the x86 architecture

Technical Analysis of DDR in Macs - Ever since Apple introduced its new line of PowerMac G4s, much debate has raged regarding the practicality of introducing DDR RAM in the current system architecture. Though some websites have released benchmarks showing virtually no performance improvements, it may not be as cut and dried as people think, particularly in regards to the L3 cache debate

AMD angered by changes in PC performance benchmarking - A widely used industry benchmark for PC performance was revised this year to favor Intel Corp.'s Pentium 4 processors, according to archrival Advanced Micro Devices Inc

Intel touts benefits of 2.8GHz P4 - As usual the big question remains why does the world need such high-speed desktop processors? Intel's answer this time around refers not to gaming, but the benefits higher performance PCs bring in encoding digital media (such as music, pictures, and movies) and for collaborative applications in business

First Tests: 2.8-GHz Pentium 4 - The tests cover only a few of the new PCs scheduled to ship with the debut of the 2.8-GHz P4. Tests included a $2849 Sys Performance 2800 PC, as well as a Dell Dimension 8200 priced at $3158 and a $2999 Gateway 700XL. Other vendors are readying new systems as well

AMD plans Athlon boost - The newest Athlon XPs will help AMD increase its competitiveness archrival Intel's Pentium 4. The Pentium 4 currently tops out at 2.53GHz, while AMD's highest performance Athlon XP is a 2200+ model, which runs at 1.8GHz

The Intel Option - based upon various statements and other anomalies i.e. selling off large quantities of G4 chips at the annual Apple garage sale. I have no personal doubt that Apple's dance with Motorola is all but over, the question remains, who will make the next generation Macintosh processor?

Apple said to be eyeing Intel chip - Whether or not Apple's operating system migrates to the Intel platform, there are some other good things coming to the Macintosh platform.

Bridging the circuit gap - The ever-shrinking size of transistors is an amazing feat of engineering, bordering on science fiction. But what happens when these transistors get so dense that traditional methods for creating electrical contacts no longer work? This is one of the biggest headaches for chip engineers pioneering the next generation of miniaturized circuits. But some good folks in Palo Alto, Calif. are already inventing their way past this obstacle

Intel Mac power has had its chips - Friends, take it from The Barrow - barring development of some remarkable new Mac-compatible chips by Intel (most unlikely) - it just won't happen. Here's why. All Macintosh software is written to work with PowerPC processors. That applies to the operating system, applications, tools, control panels, even printer drivers. Not one bit of it would work with any current Intel chip. Every single piece of software would have to be painstakingly rewritten and retested: a mammoth, hugely expensive task

Building for the Next Chip Boom - Never mind that sales are off by 30%. Chipmakers are racing ahead with snazzy new technology

If Macs Get Real POWER, Who Needs a Hammer? - We know Motorola are working on a G5 PPC processor and the most recent rumours peg it at 2.5GHz. Motorola's roadmap states it as being 64 bit and having a 13 stage pipeline. The jump from 1GHz to 2.5GHz may seem unduly vast however the longer pipeline and 0.13um manufacturing technology will allow such clock speeds so 2.5GHz does not sound unreasonable

IBM woos Apple with PowerPC "on steroids" - Though the server chip has a different name and a different design, Power4 is essentially a PowerPC processor on steroids. The two chip families are grounded in the same architectural concepts, but the Power4 contains enhancements not seen in the PowerPC family

Will Apple Put Intel Inside? - Finally, there's a good reason Apple may want to stick with the PowerPC. In October, IBM will unveil a new 64-bit version of the PowerPC chip, aimed at desktops and low-end servers, at the annual Microprocessor Forum in San Jose, Calif. By moving to 64 bits, the chip can address a great deal more memory than the current generation of 32-bit chips, allowing the chip to make faster work of complex computing tasks

Sun Blasts Intel's Itanium - Sun Microsystems Inc. delivered a scorching attack on Intel Corp.'s 64-bit Itanium processor to an audience of analysts and reporters Wednesday, deriding the chip's design and lambasting it as the "most expensive disaster in the history of high tech."

Silly Idea Department's Last (?) Word on "MacIntels" - Friends and neighbors, there is more to this absurd discussion than meets the eye. As Gene Steinberg pointed out to us last night in a typically straightforward email, everyone who rants and huffs about the topic of Apple switching to nominally faster PC processors manages to leave something out, and so did we

IBM in chips power play - The power requirements of IT systems accounted for ten per cent of US energy consumption in 1994, according to the US Department of Energy. IBM hopes to develop more energy-efficient products

IBM lays desktop PowerPC on Cupertino lawn - The new chip designed for "desktops and entry level servers", and will be an 8-way superscalar, SMP-ready design capable of 6.4GB/s throughput. Tantalisingly, the processor has it own "vector processing unit implementing over 160 specialized vector instructions."

Coursey Weighs In On Macs With 'Intel Inside' - He apparently hasn't forgotten how close Apple came to dying during the Macintosh clone days and wouldn't believe a move like this to indicate a similar plan. Instead, he supposes that there could be a way to configure things so OS X will run only on the desired hardware. This would not only protect the bottom line but also the tight hardware/software integration that Apple is known for

Intel's Banias: Not built for speed - Banias, Intel's energy-efficient processor designed primarily for notebooks, will debut at three speeds when it arrives next year, sources say--but megahertz won't be its selling point

Macs with Intel inside? You bet! Here's how - Here's a prediction: In less than 18 months, you'll be able to buy an Apple Macintosh computer with an Intel (or equivalent) processor inside. The machine will be able to boot either Mac OS or Windows, although it might not come with Windows preinstalled. I've considered--and rejected--this idea in the past. My feeling has been that, unless Apple were ready to cut the cord with Microsoft, it wouldn't attempt this kind of head-to-head platform competition. WELL, GUESS WHAT? With Apple ads encouraging Windows users to switch platforms, and Microsoft whining about supposedly slow sales of Office for OS X, it's clear that the relationship is in trouble

Apple Mac OS on Intel? Maybe - Neff, for instance, predicted Apple, which uses chips from Motorola and IBM that currently top out at 1GHz, will switch to Intel, whose chips run at 2.5GHz, to get a performance boost and gain more customers. There's a better than 80 percent chance Apple will make the jump in two to four years, he said

Apple to move to Intel? Analyst says yes - Will Apple migrate future Macintosh models to an Intel-based architecture? Writing for, Michael Kanellos points to one well-respected industry analyst that certainly thinks so

Could Apple Really Shift To x86 CPUs? - Motorola, a troubled corporate entity these days, appears to have only perfunctory interest in PowerPC Development, and the recent layoff of another 4000 personnel in Moto's semiconductor division is not an auspicious lookout with respect to a speedy debut of G5 chips. Motorola's troubles put Apple in a precarious position, and it's unlikely that Moto executives are losing any sleep over Apple's increasing MHz gap woes

It's Started Again: The Mac On Intel Rumors - Well, what MacWorld conference would complete without one of the usual perrenial rumors resurfacing and generally making a mess all over the place? No, these aren't rumors of Disney buying Apple. Not even Sun or SGI. And Apple definitely can't afford to buy Adobe. There were some pre-Expo rumors of Apple moving to IBM's Power4 processor to replace the G5 that Motorola can't seem to ship. And then there were the rumors that the Jobs keynote was somehow influenced by a pre-Expo party with a certain furless shrew looking thing and a guy nicknamed "Wobs" involving a wormwood enhanced super-beverage. But the best rumors by far were the resurfacing of the "Apple's going to move to Intel" rumors

Might Apple ditch PowerPC for Satanic chips? - IS APPLE SERIOUSLY thinking about switching processor platforms? There's been no end of speculative answers to that question over the past few years, but Apple itself has been resolute on the point: no we're not

Jobs on Intel: "we like to have options" - As the megahertz gap widens between Intel-based PCs and the latest PowerPC Macs, some analysts are urging Apple to reconsider its microprocessor strategy

AMD Pushes Athlon to 1.8 GHz - First tests find Intel, AMD match performance--but Athlon XP 2200+ is the better buy

Intel to describe functional blocks to enable 4.5- and 6-GHz processors - In various papers at the event, Intel will describe the development of new, high-speed caches and address generator units for future processors. The company will present details on new, low-power technologies, such as forward body bias. And it will also address the new and emerging problem in chip designs: soft error rates

Will new Intel chipsets speed up your PC? Find out! - Based on our first tests of systems with integrated graphics (i845G), we found performance to be similar to systems using an older Nvidia TNT2 64 card. In other words, gamers need not apply

Processors: The next commodity? - I have this business idea. I want to make it possible for anybody or any company that suddenly finds itself in a pinch for processing power to come get it from me from across the Internet

Apple aims to boost bandwidth with 1.5GHz G4s - Recent word from sources close to Motorola confirm that a significant speed bump will be timed for MacWorld Expo in July, raising current bus speeds, and seeing new 7470-based G4s raise frequencies to as high as 1.5Ghz

Apple discusses Oct-level precision in AltiVec G4 Processor - The article concerns an issue with a limitation of the Apple G4 processor and its AltiVec (vector processing unit(s)). Specifically the AltiVec processing unit only deals with single-precision floating point (24-bit mantissa) calculations and therefore has been criticized by some for it lack of double-precision floating point capability (commonly found in other processors)

Celeron chips get cheaper - Intel has lowered the list prices of its top three desktop Celeron chips by as much as 13 percent. Intel sliced the price of its 1.2GHz Celeron the most, lowering it $10, to bring the price to $69--a 13 percent drop

IBM Goes Own Way with PowerPC - "IBM is taking the focus on semiconductor power consumption to the next level. The PowerPC 405LP includes special circuitry that shuts off portions of the chip when not in use, a technique that reduces both active and standby power in chips by up to 10 times over current designs,"

Sun's UltraSPARC IV to appear in 2003 - The documents also reveal that Sun plans to transition from its midrange UltraSPARC IIIi line to the UltraSPARC IVi line when the older chip reaches 1.4GHz. The UltraSPARC IVi will reach speeds of at least 1.6GHz, and follow-on chips in this series are planned to hit 3.0GHz

The AltiVec Difference - For all it's marketing hurrah, the concept of AltiVec is exceedingly simple: it processes data in multiples, working on a whole mouthful of data instead of tackling it one nibble at a time like the integer and floating-point units. How big the mouthful is depends on the type of data

Red Hat to support PowerPC, AltiVec - Red Hat Inc. will produce a GNUPro Linux toolchain and cross compiler for Motorola's AltiVec-enabled PowerPC processors. As a result, Motorola's PowerPC customers will be able to develop Linux apps that take advantage of AltiVec

New G4 roadmaps promise Apple harvest - By this time next year three as yet unannounced versions of the G4 will dramatically boost internal bandwidth, support switched fabric interconnects, and will see the processor talk to memory at full bus speed, according to disclosures from Motorola sources

Motorola unveils low-power PowerPC G4 Plus - The low-power version of the G4, the PowerPC 7410, consumes 5W at 500MHz, its maximum clock speed. Clearly, that's less than half the 7440's consumption for only 100MHz clock speed difference, so don't expect Apple to rush out and switch all of its best-selling PowerBook G4 models over to the new CPU just yet

The Pentium 4 and the G4e: an Architectural Comparison - In my previous article on the Pentium 4 and G4e, I detailed the front ends of each processor. I also gave a general overview of each processor's pipeline, paying particular attention to the overall design philosophies embodied their respective designs. In this article, I want to look in greater detail at the back end, or execution core, of both processors. I'll talk about the execution resources that each processor uses for crunching code and data, and how those resources contribute to overall performance on specific types of applications

Introduction to AltiVec Technology - AltiVec technology expands the current PowerPC architecture through the addition of a 128-bit vector execution unit, which operates concurrently with the existing integer and floating point units. This new engine provides for highly parallel operations, allowing for the simultaneous execution of up to 16 operations in a single clock cycle

Will IBM Supplant Motorola To Supply G5s? - Although the thought has probably crossed the minds of all who have followed the G5's progress, more and more people have been asking whether Motorola (NYSE: MOT), in its current troubled state, is equipped to deliver the next-generation processor

Intel continues Rambus support with chip set for faster Pentium 4 processors - The new Pentium 4 processors also support both 400- and 533-MHz bus speeds. Previously, the company's Pentium 4 processor line and chip sets only supported the 400-MHz systems bus

Intel Rolls Out 2.53GHz P4 - Earlier this month, Intel executives told Wall Street analysts the company was still on target to hit its 3.0GHz milestone late in 2002

IBM adds TCP/IP coprocessor to PowerPC - IBM Corp. has tailored its PowerPC architecture for packet processing by adding a TCP/IP coprocessor to its latest 440GX device. Designed to take most of the strain off the CPU during packet processing, the TCP/IP assist engine handles checksum generation logic for packet headers and data in transmit, provides checksum verification logic in the receive path and supports TCP segmentation in transmit

Future of the PowerPC Part 2: PowerPC Today and Tomorrow - If you look at the world of powerful computers, you'll find several features that make them fast, powerful, robust, efficient, and scalable. They may have redundant power supplies, arrays of hard drives, and multiple processors. It's the latter I want to look at here

Motorola adds Bluetooth baseband to Dragonball processor - Motorola's Semiconductor Products Sector is launching a version of its DragonBall MX1 microprocessor that integrates a Bluetooth baseband hardware accelerator

Intel's CEO chats about new chips - Intel has said the new chip, which can do everything from application processing to storing data and refining analog signals, should help device makers cut costs and reduce power consumption. These benefits could then lead to smaller handsets with longer battery life, for example

Intel rolls out world's fastest 2-GHz processor for notebooks - Hoping to jumpstart the slumping computer industry, Intel Corp. here today announced the world's fastest microprocessor for notebook PCs--a 2-GHz chip built around its Pentium 4 MPU architecture. The Santa Clara-based company also rolled out a 1.9-GHz version of its mobile Pentium 4 processor line, while announcing 1.33-, 1.4-, and 1.5-GHz models of its Celeron family of MPUs for lower-cost notebook PCs.

Intel speeds Xeon to 2.4 GHz, launches new Pentium 4 mobile series - More than 30 new laptops are expected to use the new Pentium 4 mobile processors, with systems starting at a price of around $1,300

IBM, Motorola paths diverge for future microprocessors - IBM has slowly and quietly moved off the Mac in the past year. Its G3 processors, which used to live on three-quarters of all Macintoshes, now only ship on iBooks. Motorola's G4 processor has gone from use only in desktop G4s to now include the iMac and the Titanium PowerBook. In terms of numbers, Motorola has locked up Apple as the company's number one supplier of processors

Motorola's MHz = Mega Hurts - What I believe Motorola (NYSE: MOT) doesn't want you to know is that this obsolescence seems to have been planned from the beginning of its involvement in the PowerPC fiasco. Angered by Apple's choice of IBM's (NYSE: IBM) PowerPC architecture over its own "RipFire" 88k series, Motorola apparently decided to back Apple's decision despite the fact that it had something better that Apple desperately needed at that point: the M68060, the sixth CPU in the hot 68k family. Motorola remained mum on the new specs for the '060, and Apple purchased the PowerPC 601 from IBM, which would act as a time bomb set to destroy Power Macintosh performance

Fishtank Watercooling - I was thinking of a suitable resevoir for my water supply when I was flicking through an Argos catalogue and stumbled across there fish tank section, I thought this would be ideal but I didnt want to make the res out of plastic so I went to a local aquatics centre and bought a 7 gallon glass tank

The Trio Tackling Tomorrow's Chips - The IBM-Sony-Toshiba deal to develop next-generation chipmaking techniques could change the industry's "entire landscape"

The AltiVec Difference - In early February 2002, Apple announced an accelerated implementation of BLAST, a bioinformatics tool from the National Center for Biotechnology Information (NCBI). This software is used for protein and DNA searches in biomedical research and drug discovery. Co-developed with Genentech, this high-throughput version of BLAST takes advantage of AltiVec technology on the PowerMac G4 processor, running up to five times faster than the standard BLAST implementation.

AMD and Intel war over benchmarks - Intel is training resellers in the art of discrediting the way AMD rates its processors, calling it 'bad science'. AMD says the comparisons are irrelevant

PowerPC stuff - The PowerPC, or PPC for short, is a CPU ISA jointly developed by the AIM (Apple-IBM-Motorola) Consortium back in the early 90's. It has been driving Apple's PowerMac line and advanced Amiga computers since 1994, and has been extensively used in embedded devices as well. This article gives a brief presentation of the current span of the PPC family

Intel addresses concerns over Pentium 5 - Earlier today, Intel executives addressed the mounting concerns over the immense power supply necessary to utilize their upcoming Pentium 5 chip. The Pentium 5, also known as the Pentapentium, suffers from a huge power drain on the system, which has forced the development team to look for creative solutions

IBM to share chip intelligence - Sony and Toshiba have expanded a deal so they will be able to incorporate some of IBM's chip-making advances into consumer devices such as cameras and PlayStation consoles

Intel introduces 2.4-GHz Pentium 4, targets 3 GHz by year's end - ╩ Intel Corp. today officially launched its 2.4-GHz Pentium 4 processor, which the company claimed is now the world's fastest microprocessor for desktop computers. The central processor unit is being fabricated by Intel on 300-mm and 200-mm wafers using the company's 0.13-micron process technology. The 2.4-GHz Pentium 4 has 512 kilobytes of level-two cache and is selling for $562 each in quantities of 1,000 units. Intel said it is also shipping "boxed" Intel Pentium 4 processors with speed up to 2.4 GHz for system integrators.

Intel to launch P4 chip at 2.4 GHz - A company spokeswoman confirmed that the chips will cost about $560 each in thousand unit quantities. The chips are for use in high performance desktop personal computers

As The Clock Ticks: Has Apple Lost The Megahertz Race and Does It Matter? - Where has Apple been the past four years? In 1998, you had Apple "steamrolling" the Pentium laptop market with "a processor up to twice as fast." Ditto for the PowerMac desktops. Apple had Macs running at clock speeds comparable to Pentiums. After the past few years of losing this "war," it has given WinTel users yet another way to unfairly put down Macs. One even forgets what it was like to have a Mac with a similar clock speed to a WinTel box. So where has Apple been, while they "lost the war"? Could it be that they have been developing something better?

10. Research from the Advanced Computation Group - The research papers herein are based on work in Apple's Advanced Computation Group (ACG). The ACG is responsible for working out advanced applications for science, education, and engineering sectors; and also for general algorithm development pertinent to MacOS. The ACG has developed algorithms to exploit Velocity Engine technology, in this way to accelerate operations for graphics, cryptography, scientific computation, real-time signal & image & video processing, advanced algebra, compression, and so on.

IBM 'produced 110GHz chips' - IBM researchers announced last week that they'd built silicon germanium transistors with a speed of 110 gigahertz. According to The Boston Globe, the chips will be based on new proprietary technology that creates transistors that switch on and off 110 billion times per second.

Opinion: Do buyers care about chip speed anymore? - This line of thought leads to the question: "Do people really make their upgrade decisions on the basis of chip speed anymore?" "They really don't," Giga Information Group analyst Rob Enderle told NewsFactor.

Chip Advances Chase Moore's Law - Not every week brings exciting news for fans of semiconductors, but this week is one that all electrical engineering majors are sure to relish. On Monday both Intel and IBM announced chip advances that they say will significantly speed up computing processes -- and during the next few days, at separate conferences, each will show why they're keeping pace with Moore's Law

Megahertz myth - Pat Moorhead is a man with a mission. As the vice-president for customer advocacy - silly title, serious task - at AMD, the silicon chip maker, Moorhead wants to persuade the PC-buying public that clock frequency, the measure of a computer processor's pulse-rate and the prime gauge of chip performance over the past 20-30 years, is no more relevant today than MS-DOS

Intel launches net processors running at 22,400 MIPS - The 1-GHz version also embeds 16 RISC engines. Each engine runs at 1-GHz for a total performance of 16,000 MIPS. Total memory bandwidth is 51-gigabits-per-second, according to Intel. Based on 0.13-micron technology, the IXP2800 also has a memory interface that supports Rambus' high-speed RDRAM chips

Intel CEO predicts 30-GHz processors on 450-mm wafers in 2017 - What will the semiconductor industry look like in the year 2017 or so? Semiconductor technology will remain alive and well for at least the next 15 years, enabling the eventual development of 30-GHz microprocessors on 450-mm wafer substrates for chip production, predicted Craig Barrett, chief executive officer of Intel Corp. of Santa Clara, Calif

Mac3D: G4 vs PIII shootout yields poor Mac G4 performance and controversy - I had felt the report was unfair and I did not dispute the results but had a number of issues with how the test was performed

Update on Q3 and Altivec - id Software's Graeme Devine made a post to the Quake3World forums regarding some enhancements he was making to the Mac version of Quake 3: Arena. Specifically, he was working on Altivec instructions which should give G4 owners a significant boost

Carmack confirms Slashdot comments, talks Altivec - PPC CPUs are as good as, or slightly better than, x86 on a clock for clock basis, but they can't overcome the large MHz gap that exists," said Carmack. "Altivec has some wins, but it won't make any significant difference unless the performance is extremely focused in a small area, and the balance of computation and bandwidth is just right."

The Motorola [7450] G4+ Processor Core -- Does It Make The Cut? - Motorola released the significantly improved "G4+" processor, which promises to dramatically (and positively) affect Apple's status in the market. G4+ basically takes G4 and improves it all-around in a bunch of nice ways

Nightfall developer responds to AltiVec questions - If you want to see what an AltiVec game can look like, go look at the Playstation2 games. G4 Macs are closer to its performance than PentiumIII PC's. We are talking games where the characters have memories, the physics is amazing (throw a stone in a pond and see the real ripples lap against the shore - not fake texture effects

Where are the AltiVec games? - AltiVec just doesn't have that large of a role in today's 3D games where 3D hardware is used (which is true of every G4 Mac). 3D cards do a much better and faster job of rendering than an AltiVec software renderer could do. The main thing AltiVec can do is speed up the transformation math

Pentium IV versus G4 - Risc processors (Reduced Instruction Set Computing) like Motorola`s G4 can execute more instructions than their Cisc-pendants (Complex ISC) at the same clocking. That means in practice that a Cisc chip, how it is normally used in a X86-compatible by AMD and Intel, must divide a complex statement (for instance an instruction) into several statements

Gauging the gigaflops gap - what is a gigaflop and should we give a flip? Perhaps we should figure out what a "flop" is -- let alone gigaflops -- before deciding whether it matters.

New G4 chip hits 1 GHz; Apple plans uncertain - With the upcoming "Apollo" processor, Motorola's G4 processor family will be able to join the 1-GHz club, David Bearden, senior member of the technical staff at Motorola's Somerset Design Center, told an audience at the Microprocessor Forum taking place this week in San Jose, Calif

PowerPC G4 Plus taped out - sources have added their voice to earlier hints that Motorola has completed the PowerPC G4 Plus, a process known in the trade as 'taping out'

PowerPC G4 Plus in Macs by "mid-summer" 2001 - sources confirm that Motorola has begun to release fully-working samples of its next generation PowerPC G4 Plus and that Apple will have product at speeds of around 750MHz that could hit the market by "mid-summer" 2001 or earlier

Motorola upgrades PowerPC G4 - Motorola yesterday unveiled its latest PowerPC G4 processor, the 7410, but the new processor is unlikely to please Mac users looking for a chip capable of catching up with Intel's ever-growing megahertz lead

Where the hell is... the PowerPC 'G4 Plus' - getting the PowerPC 7400 above 500MHz has proved difficult, to the extent that Apple has been forced to ship dual-processor machines to help convince buyers that its Power Mac isn't lagging way behind Wintel.

MacWorld - "Fantastic Four: With the Power Mac G4, Apple Brings Super Power to your Desktop"

EEMBC Publishes Benchmark Scores for Motorola PowerPC Processor - "The performance of Motorola's MPC7455 is tremendous," said Markus Levy, EEMBC president. "But it is equally significant that this performance has been certified according to objective, unbiased benchmarks that the majority of the microprocessor vendors in the world have agreed upon

Motorola talks about the Apollo G4 1GHz - William Swearingen, Director of Strategic Communications at Motorola, told MacCentral that the G4s driving Apple's new G4 mini-tower systems are indeed the long anticipated Apollo processors. Labeled MPC 7455 and MPC 7445, the Apollo G4s achieve all of the goals that Motorola outlined at the 2000 Microprocessor Forum -- namely GHz+ performance, fabrication using SOI (Silicon On Insulator) technology, the ability to have a 2MB DDR (Double Data Rate) L3 cache, and a superior power consumption/performance ratio

Faster PowerPC also saves energy - Motorola is the first chipmaker to bring SOI to the desktop. The process places an insulator between a transistor and the silicon bed that a transistor rests upon inside a chip. The insulator works like a sweater on a cold day. By preventing energy leakage from a transistor into the silicon, it allows a transistor to switch on and off more quickly. Thus, a chip can reach a higher clock speed for a given voltage or use less power to maintain a specific clock speed

Apollo fires-up chips chief - The Embedded Microprocessor Benchmark Consortium (EEMBC) has published its benchmark scores for Motorola's MPC7455, the so-called 'Apollo' chip used to power 933MHz and dual-1GHz Power Mac G4s.

Motorola pushes PowerPC to 1-GHz with SOI technology - Pricing for the 800-MHz MPC7445 has been set at $125 each in quantities of 10,000. The 1-GHz MPC755 has a suggested retail price of $295 in similar quantities

Motorola brings server technology to the desktop - Motorola's latest PowerPC 7455 chip uses silicon on insulator technology, primarily used in server chips, to improve its performance

Engineers are making chips run ever faster. Some even say, Why not increase the speed of light? - Why are chips hitting the speed wall? It's partly because of how they're made. Engineers produce transistors that are very small and tightly packed together, which means electricity has less distance to travel as it does its work-

New Processors From Intel Complete Transition Of Its Entire Mobile Product Line To 0.13-Micron Process Technology - Smaller chip geometries, enabled by this advanced chip making process, result in lower power consumption and smaller size while enabling higher levels of performance

A new spin on computing UC scientists suggest way to harness electrons for processors - A team of researchers at the University of California at Santa Barbara has taken a key step by suggesting for the first time a practical way to bring the elusive phenomenon known as "electron spin" under precise control. Experts said it opens up a path toward a whole new style of computing, one that is expected to be particularly useful at performing calculations that stymie conventional machines,

Motorola says PowerPC G4 Apollo to ship early 2002 - Motorola has confirmed that the next generation of the PowerPC G4 family, codenamed Apollo, will ship early next year - if the company sticks to its current release schedule. The admission, made by a Motorola spokesman cited by Web site MacCentral, makes the launch of faster Power Mac desktops at Macworld Expo in San Francisco early next month more likely

Motorola Readies G5 Processors - Though the new information is slight, for many it reinforces speculation that Apple will release new desktop computers based on Motorola's "G5" family of processors, perhaps as early as January's Macworld Expo/San Francisco trade show, sources said

Motorola updates PowerPC 7450 - Motorola has quietly extended its PowerPC family with two G4-class CPUs: the MPC7451 and the MPC7441. Both parts appear to be basic updates to the existing MPC7450 and 7440. The 7450, also known as the G4 Plus, was Motorola's second generation of G4 processor while the 7440 is a low-power version designed for mobile systems.

Motorola's G5 Processor - Just the Facts and a Little Speculation - A few facts here, a few leaks there. Add intuition and some good old-fashioned guesswork, and almost all of the information about this upcoming processor has been of little relevance to the analysts who are trying to create a semi-accurate roadmap for the chip's future. In an attempt to bring about clarity to this silicon silliness, I'd like to present what I believe to be a more accurate speculative analysis than most, using verifiable information that we already known to be true, but has not yet been widely reported

The Pentium 4 and the G4e: an Architectural Comparison - In this article, I want to look in greater detail at the back end, or execution core, of both processors. I'll talk about the execution resources that each processor uses for crunching code and data, and how those resources contribute to overall performance on specific types of applications.

Prelim PowerPC G5 hits 2.4GHz - Motorola has released the latest update to its PowerPC 8500 - aka G5 - processor that ups AltiVec performance and delivers consistent 1GHz and up clock speeds, one of our Apple sources tells us. Indeed, the source claims, two of the chips in the sample set of CPUs sent to the Mac maker, clocked at 2.4GHz. Most, however, ran at 1GHz, 1.2GHz or 1.4GHz, and some - a "considerable number", says our Deep Throat - operate at 1.6GHz.

PowerPC G5 'blazingly fast', claims Motorola mole - Motorola sources have confirmed what Apple insiders tell us: that the next generation of PowerPC processor, the PPC 8500 - aka G5 - is now consistently coming off the production line at 1.6GHz, and that it is a very fast chip.

Transitive creates 1GHz PowerPC on Athlon - The company's software is designed to ultimately allow software written for any platform to run on any other platform UK and California-based software firm Transitive Technologies plans to make software that will effectively create a 'virtual' PowerPC chip running on an x86 processor within 18 months

PowerPC G5 performance 'stunning' - sources - The G5 is the next major version of the PowerPC architecture and includes a new internal bus structure, a longer, ten-stage instruction pipeline, redesigned integer and floating-point maths units. It will be offered in 32-bit and 64-bit versions, and fabbed using silicon-on-insulator technology at 0.13 micron

Motorola, IBM Unveil New PowerPC Cores - Motorola and IBM outlined the future of the PowerPC Wednesday at the Microprocessor Forum

IBM to unveil faster G3 CPU next week - IBM will next week unveil the latest member of its G3-class PowerPC 750 family, the chips that currently power Apple's consumer computers, the iBook and iMac

IBM will take the wraps off a gigahertz-capable PowerPC chip on Monday at the Microprocessor Forum, one of the year's top events for the silicon set - The new PowerPC 750FX, which will come out at 750MHz but will be able to reach 1GHz in subsequent versions, will be the first IBM chip to use a new manufacturing process called CMOS9S. This combines recent chipmaking innovations--including copper wires, silicon-on-insulator (SOI) technology and low-capacitance dielectrics--with a 130-nanometer (0.13-micron) manufacturing process.

Motorola completes 1.6GHz PowerPC G5 - Motorola taped out the PowerPC 8500 - aka the G5 - last week and is set to go into volume production real soon now at speeds of up to 1.6GHz - a higher clock speed than AMD's latest-generation, 'Palomino' Athlon is expected to ship at - The Register has learned

Beyond MHz and GHz - Selling processors by something other than megahertz speed isn't a new idea. Some companies have used model numbers to mislead the public, while others claim they are helping consumers better understand the real performance of their processors

The latest P4s: more beauty than brawn? - Until now, Pentium 4 PCs were priced out of reach of most users. But thanks to Intel's new i845 chipset, computer makers can combine the P4 with less expensive SDRAM rather than RDRAM, so you'll get more clock speed for the cash. The only catch is that SDRAM isn't as fast. Will these new systems deliver a whole new level of bang for the buck? Or are the tradeoffs in performance and features simply too great?

Motorola updates G5 specs - Motorola has released more details of its next-generation PowerPC processor - the G5 - and updated its PowerPC road map

The Pentium 4 and the G4e: an Architectural Comparison - As this article will show, the successor to the most successful x86 microarchitecture of all time is a machine built from the ground up for stratospheric clock speed.

IBM paves way to 100GHz chips - The transistor worked at speeds up to 210 GHz, while using only a milliamp of current: commercial communication devices running at 100 GHz are expected in the next two years, much sooner than expected

Big Blue designs faster chip - Just two weeks after Intel announced the development of new technology it said would enable processors to reach speeds of 20 GHz by 2007, IBM today will announce another advance it says will enable chips to hit 100 GHz as early as 2003.

PowerPC G5 to hit 2GHz - Motorola is pushing ahead with the design of the PowerPC 7500 - aka G5 - company sources have claimed, according to a report over at MacOS Rumors

Geeks declare war on Intel - Chip-heads say flaws in the Pentium 4 prove the high-tech giant is sacrificing engineering principles for marketing goals.

PowerPC 750 vs. 750cx: differences explained - Normally,there isn't too much fluctuation in design within the same generation of processor■IBM or Motorola may shrink the die (update the process), but they don't radically change the design. However the 750 and 750cx are somewhat different designs.
