When it was introduced, 64 MB DIMMs were the largest available on the market, making for a maximum memory limit of 768 MB. The logic board has a total of 12 memory slots like the Power Macintosh 8100, installing memory requires removing the logic board from the case. The 9500 is also the first computer from Apple to support 168-pin DIMM memory modules, and the 512 KB of on-board 128-bit-wide cache utilizes copy-back instead of write-through, offering faster speeds than prior Macintosh models, as well as the ability to install single modules. Users can purchase their own PCI graphics card or opt for Apple's 64-bit accelerated PCI video board with 2 MB of VRAM as an optional accessory.' Infoworld's Anita Epler noted that 'Because most multimedia developers don't use the onboard video found on previous Mac models, Apple wisely economized by simply leaving it out. This is also the first Macintosh to use the PCI standard, with six PCI slots available - one of which must be used for a graphics card. Available were single-processor cards ranging from 120 to 200 MHz, and a dual processor card with two 180 MHz CPUs. The CPU is connected via a daughterboard, and so can be swapped easily. The 9500 includes several technological firsts for Apple. The 9500 was replaced by the Power Macintosh 9600. Its speed and expandability should also made it popular in the scientific and technical markets.' Their benchmarks showed that the 9500 overcame the Quadra 950's performance deficit when running older Mac software in the Mac 68k emulator, posting speeds almost twice as fast as the Quadra 900.

but it is an excellent foundation for a high-end graphics workstation - for color publishing or media production.

MacWorld Magazine gave the 9500 a positive review, concluding that it is 'not the second-generation Power Mac for the rest of us - it's too pricey. The 180MP and 200 MHz models, introduced August 1996, use the enhanced PowerPC 604e processor. It is powered by a PowerPC 604 processor, a second-generation PowerPC chip which is faster than the PowerPC 601 chip used in the Power Macintosh 8100. The Power Macintosh 9500 (sold as Power Macintosh 9515 in Europe and Asia ) is a personal computer designed, manufactured and sold by Apple Computer, Inc.
