milo, re:spitfire cache, Didnt we speculate in the past, Spitfires would be Thunderbirds in which 1/2 of their 256k L2 cache didn't pass? ie-dump them cheaper? Wag steve

Milo - RE: "Paul it has 64k L2 enabled and another 64k that can be turned on via BIOS is what I read on Ace's I believe. I believe this is done for a greater yield." Ace's Hardware reported this was possible with the desktop K6-2+ not Spitfire, except with 128K enabled and 128K disabled, but this processor has been canned.

Milo, <Paul it has 64k L2 enabled and another 64k that can be turned on via BIOS is what I read on Ace's I believe. I believe this is done for a greater yield.> I doubt it. On a 0.18u process, the difference between 64K and 128K of L2 cache is only about 8 to 10 mm2. That's almost negligible compared to a core size of about 103 mm2. I'm pretty sure that AMD will make sure Spitfire has enough cache to make it faster clock-for-clock than Celeron at the very least. Spitfire can't compete against Celeron in pure cost (both CPU and platform), but AMD can market the MHz and per-clock performance advantage. That should make Spitfire an interesting competitor in the low-end until Timna shows up. Tenchusatsu
