Right now, the AMD Athlon's FSB to the chipset is 200Mhz (or 100Mhz DDR), but the memory bus is still 100/133Mhz (depending if you are using the original AMD 75x chipset or the VIA chipset). So you are still somewhat running at 100/133Mhz. Also, not all Pentium III processors run at 133Mhz. Some still run at 100Mhz (but those are fading out). The Pentium III Xeons without the standard Coppermine 256K L2 cache (which is replaced with 512K, 1MB or 2MB of either in-package or external L2 cache) runs at 100Mhz FSB. When the new DDR SDRAM chipsets come out for the AMD Athlon, then the CPU FSB and the memory FSB will run at 100Mhz DDR (or 200Mhz). The Tualatin (the next generation Pentium III at 0.13-micron) will probably run on a 200Mhz FSB (don't know if it's 100Mhz DDR or straight 200Mhz). // Linh Pham // http://closedsrc.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
