PowerLogix ,contrary to our expectations, has come out with not one but two upgrades for the iMac. Dubbed the iForce, these upgrades work in iMacs A-D (233MHz to 333MHz machines). How do these cards compare with Newer's iMac upgrade? Well for one thing there is a low-end card running at 400MHz with 512K of backside cache running at half the processor speed (200MHz) and also a high-end card with a processor speed of 500Mhz and 1MB of backside cache running at 40% of the processor speed (200MHz). The Newer card has a processor speed of 466MHz and 1MB of backside cache running at 30% of the processor speed (155MHz). While the Newer card has a full MB of backside cache it is hobbled somewhat by the slower speed.
In addition PowerLogix says that they have created this card from the "ground up", instead of recycling old iMac processor daughter cards, which is the way Newer creates their iMac upgrade.
We are waiting to hear from PowerLogix how they did this (since the Apple ROM resides on the original daughter card and you cannot run an iMac without it). This approach will be a boon for iMac users who want to upgrade, as they will be able to hold onto their old processor cards instead of returning them for a rebate (which you have to do with Newer, or the card will cost you $150 more than the current price of $449).
PowerLogix says the iForce should be available at retailers sometime later this month. We plan to do a review of both cards as soon as they are available...so stay tuned.
Below we explore what performance gain you will see with these cards installed in the machines they are made for. We are including scores for the current iMacs so you can make a speed comparison to those as well. We also take a comparative look at the price/performance equation of each card.

PowerLogix Press Release
AUSTIN, TX --June 8, 2000 -- PowerLogix announced today that they have expanded their award-winning line of G3 and G4 processor upgrades to include the dynamic, new iForce upgrade for the immensely popular iMac computer from Apple. "We are the first manufacturer to offer a no-hassle, low cost alternative to the millions of iMac owners," said Robin Sharp, Marketing Director for PowerLogix R&D, Inc. "The iForce offers bold performance increases at only a modest cost. This is the first and only "from-the-ground-up" iMac processor card design, not simply a remanufactured Apple card. We are offering a full 1mb of backside cache on our high-end iForce model. This is double the size of even the latest iMacs from Apple, resulting in more performance at hundreds of dollars less than the cost of a new iMac."" The iForce ships with either 512k or 1MB of backside cache running at 200 MHz. iForce Model List Price 400/200/512k $299 500/200/1MB $499 MacBench 5.0 tests indicate that even with the low priced 400MHz card, users can increase the performance of their iMac by 150%. The high-end 500Mhz iForce will make even the early iMac 233 a full 145% faster than the latest iMac DV.
