Dan, I'm saying that Athlon doesn't really need a 200 MHz bus at the moment because the memory is only running at half-speed. If Athlon's bus was only running at 100 MHz, I'm sure we'll still see almost the exact same benchmark scores that we're seeing right now. <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.> Close to a straight line? I saw some leveling out at higher speeds when running Quake 2 Crusher and Expendable. I'm not too familiar with the Bapco Sysmark, but if it's anything like Business Winstone 99, it won't exercise memory bandwidth all that much. As for 3D Studio Max, I think that program is much more CPU-dependent (specifically FPU dependent) than memory-bandwidth-dependent. Like I said in a previous e-mail, today's benchmarks probably aren't going to see a dramatic improvement with the newer memory technologies. A lot of things can change over the course of a year or two, you know. <The constraint is always the video card, not the CPU or the memory bus.> You're own words betray you. If the constraint is the video card, we shouldn't have seen the "straight line" improvement going to higher processor speeds. <VC266 has roughly 4 times the throughput of 100MHZ SDRAM.> Dan, would you mind explaining to me how VC SDRAM works? Or at least could you point me to some technical papers describing VC SDRAM? I already know a lot about RDRAM and its technical details. www.rambus.com is a great source of info. Is there a www.vcsdram.com anywhere? (By the way, foils don't count as "technical papers.") Tenchusatsu P.S. - Amazingly, I know more about RDRAM than SDRAM. Go figure.
