The Power Macintosh 9500 (sold as Power Macintosh 9515 in Europe and Asia) is a personal computer designed, manufactured and sold by Apple Computer as part of the Power Macintosh line from May 1, 1995 until February 17, 1997. It is powered by a PowerPC 604 processor, a second-generation PowerPC chip which was faster than the PowerPC 601 chip used in the Quadra 950. The 180MP and 200 MHz models, introduced August 1996, use the enhanced PowerPC 604e processor.
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 .... but it is an excellent foundation for a high-end graphics workstation -- for color publishing or media production. 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.
The 9500 includes several technological firsts for Apple. The CPU is connected via a daughterboard, and so could be swapped easily. Available were single-processor cards ranging from 120 to 200 MHz, and a dual processor card with two 180 MHz CPUs. This is also the Macintosh to use the PCI standard, with six PCI slots available -- one of which is used for a graphics card. It's also the first to support 168-pin DIMM memory modules, and the 512KB of on-board 128-bit-wide cache utilizes copy-back instead of write-through, offering faster speeds than prior Macintosh models. A regular 10BASE-T ethernet port is included for the first time, alongside the AAUI port, as is support for the new SCSI-2 Fast standard.
The basic design of the logic board, called "Tsunami", was used by various Macintosh clone makers as a reference design  and a modified version was used in the non-Macintosh Apple Network Server series.
Utilizing a third party G4 CPU upgrade and the XPostFacto installation utility it is possible to run up to Mac OS X v10.5 "Leopard" on a 9500, making it the oldest model capable of running Mac OS X.
The 9500 was replaced by the Power Macintosh 9600.
