Max, Re: Athlon/Tbird performance. Yup so far the performance is less than compelling although these 700's may have been crippled somewhat. However the Duron's performance seemed faster than Athlon classic. I suspect the Duron will be a much better value than the tbird, but the same can be said for celeron and cumine. However Intel cripples the memory bus on celery for differentiation - which seems pretty smart. I see duron/tbird being very similar performance on a clock 2 clock basis at least until the 760 and DDR in Q3. In the meantime he key for tbird/duron is DECREASED cost, INCREASED MARGINS for AMD as opposed to killer performance. regards, Kash

(1) M__a__x makes a good point about cache / 700MHz The 1GHz tbird should womp all other the 1GHz athlon, since the latter runs with 1/3-speed L2. (2) c't says they couldn't get a processor to test from AMD, and procured this 700 MHz CPU through "other channels". Might this be an early engineering sample? Might improvements have been made in the production silicon? I expect we'll know in... 36 hours or so, but it's fun to speculate. Comments? Doug

Max, T-Bird is not going to show a huge performance improvement over Athlon on most benchmarks. The reason is very simple. Athlon has a huge (128K) L1 cache, which gets a high hit rate. Speeding up the L2 for the infrequent L1 misses will produce only incremental performance improvement. This is a different situation from the PIII->Coppermine transition, because PIII has a small (32K) L1 cache. If there is a big performance bonus from T-Bird, it may be in clock speed from Dresden. Don't count on big benchmark numbers from T-Bird, because you will be disappointed. Scumbria
