Another thing to consider is that that 8500 has the 604 processor, the 6400
>has the 603. The difference is (roughly from what I've read) the

** The 6400 has a 200 MHz 603ev cpu, with 40 MHz 64 bit bus, 256 L2 cache
and two 16 KB L1 caches, one for data, one for instructions. It has only 1
MB of VRAM, not upgradeable.
The 8500 has the older 604 cpu, not the newer 604ev cpu, which is much
faster than the 604.
The older 604 has 2 16 KB caches... 16K for data and 16K for instructions,
256K L2, and 40 MHz bus with 64 bit data path.
Since the caches, bus speed and width are the same, the question is... how
many instructions per cycle can each cpu handle?
