The first generation of Power Macintoshes had shipped with NuBus, but by the end of 1993 it was becoming clear that Intel's PCI bus was going to be the widely adopted future of internal expansion. Apple's position as a relatively small player in the larger personal computer market meant that few device manufacturers invested in creating both NuBus- and PCI-compatible versions of their cards. The first PCI-based system was the range-topping Power Macintosh 9500, introduced in May 1995. This was followed shortly afterwards by the introduction of the "Power Surge" line of second-generation Power Macintosh systems – the Power Macintosh 7200, 7500 and 8500. The 8500 and 9500 were built around the new PowerPC 604, offering speeds starting at 120 MHz. InfoWorld's review of the 8500 showed a speed improvement in their "business applications suite" benchmark from 10 minutes with the 8100/100, to 7:37 for the 8500/120. They also noted that the 8500 runs an average of 24 to 44 percent faster than a similarly-clocked Intel Pentium chip, increasing to double on graphics and publishing tasks.
