Power Mac 9500 Usingthe same case as the 9150, the 9500 was thefirst Power Mac tower with a replaceable CPU daughter cards. Unlikethe first generations Power Macs, the 9500 had PCI slots and usedthe PowerPC 604 processor, a significantly improved,second-generation PPC design.

BYTE magazine (October 1995, p. 123) noted that the 132 MHzPowerPC 604 in the 9500 was 87% faster than a 133 MHz Pentium forinteger operations, 72 percent faster for floating point. Not quitethe "twice as fast" we'd see with the G3, but very respectableperformance.
