PowerMac Upgrade & Troubleshooting
Discussion Forum


The Power Mac 7200 made its debut in the summer of 1995 as part of the second generation of Power Macs, which also included the 7500, 8500 & 9500. This generation of Power Macs turned its back on the NuBus slot, in favor of 3 PCI slots in each model, and replaced SIMMs for DIMM type memory.

The 7200/90 was the entry level model of the Power Mac line and was aimed primarily at the business, home office and consumer markets. Also released at the same time was a 75MHz version of the 7200.

A few corners were cut to keep costs down. The 7200s accepted less RAM than their brethren, the CPU was not replaceable and the cache & RAM busses were only 64-bits wide (as opposed to 128)

In fact on the 7500/90 no L2 cache was installed, though the option to add one was available. Adding a L2 cache can significantly improve the processing performance of the machine.

This machine came with 1 MB of VRAM which can be upgraded to 4 MB for 24-bit color at 1024 x 768 resolution. (The 75MHz version of this Power Mac could only be upgraded to 2 MB of VRAM)

Though the 601 PowerPC processor is soldered to the motherboard Sonnet has engineered an upgrade for this machine that utilizes one of the PCI slots.

The 7200 was considered inexpensive at the time and sold very well.

Below you will find the MacBench 4.0 results for most of the processor upgrades available for this machine.

** Note that MacBench does not take advantage of the Velocity Engine (AltiVec instructions) of the G4. For AltiVec accelerated applications you can see a 1.4 to 4 times performance improvement over the G3, depending on the application and the functions you are trying to perform.
