Re: Athlon's 200 MHz bus is useless when running with PC100 SDRAM...

Useless at what, running membench? Or some other irrelevant to actual applications benchmark?

Tom's hardware benchmarked the Athlon from 500 to 800MHZ using memory running at 100MHZ and it was close to a straight line for video performance. There is no performance constraint from PC100, and VC266 has roughly 4 times the throughput of 100MHZ SDRAM. The constraint is always the video card, not the CPU or the memory bus.

Rambus is an interesting technology, but it isn't necessary for performance.

Note that Tom used the best memory he had, certified by crucial at 133MHZ. But I didn't see any discussion of overclocking the bus for either the Athlon or the Pentium III he was also testing. If he was running at 133, it doesn't affect my point (but the multiple for VC266 becomes 3 or so) Rambus is still not "required".
