The Power Macintosh 9500/132 was part of the second generation family of PowerMacs that hit the market in the summer of 1995. It sported a couple of innovations over the previous PowerMac generation; the introduction of the faster 604 PowerPC processor and the movement from NuBus expansion slots to faster PCI slots. The Mac OS too was undergoing improvement at the time which also lent increased SCSI and 680X0 emulation performance to the machine. Just as with the current introduction of Firewire and USB, there was the concern that there were not enough PCI cards on the market for the Mac at the time of the 9500/132's debut. This was of especial concern for this machine because it shipped without on-board video and the purchaser was expected to purchase their own PCI video card. The machine was considered a good performance improvement over its predecessor but required almost complete disassembly to install additional RAM.

The 604 processor resides on a separate daughter cards making it easily upgradeable. The machine shipped with 512K of L2 cache. Another innovation was the use of 168-pin Dual-In-Line Memory Modules (DIMMs) that took better advantage of the 9500s 64-bit data bus. Additionally the memory could be interleaved (installed in identical pairs) for a 10-15% processor speed improvement. The machine shipped with 16MB of RAM and which was expandable to 768MB. There are 6 PCI slots, with special bridging chips that do some of the processing that was previously performed by the CPU. The drive capacity is 2GB, and there is internal SCSI-2 (10-MBps) support for additional drives. The machine has two drive bays for 3.5-inch drives, though connecting drives in this particular machine requires some dexterity. A 4X CD-ROM player rounds out the attributes of the 9500.

Below you will find the MacBench 4.0 results for most of the processor upgrades available for this machine. These results are what the individual manufactures publish for their cards. In other words the speed trials were run by the manufacturer. For an independent evaluation of these cards check the Processor Upgrade Page to see if we have results available. The bar graphs below express results as a percentage of improvement over the base machine, which receives a score of 100%. Further down the page you will find a table with the actual MacBench score.
