Some info/speculation on the next Intel core, due out by the end of the year, probably at 4GHz: http://www.chip-architect.com/news/2003_03_06_Looking_at_Intels_Prescott.html Looks like it will have much higher (I'm guessing ~20%?) per-clock performance than current Pentium 4s. That would give it a SPECint of ~1770. (It will run multithreaded programs much faster, too.) A 2GHz Opteron gets 1202. If AMD can get their chips up to 2.5GHz at the end of the year, that means a SPECint of ~1502. (I figure 2.5GHz because that's the limit of Athlon overclocking right now, just like 4GHz is the limit of P4 overclocking. Opteron might run faster because it has more pipeline stages and SOI, or it might run slower because AMD is apparently having problems with SOI. So I'd call it a wash and say 2.5GHz right now. Notice that these are Opteron scores, not Athlon 64 scores, so the systems we'd actually buy will likely be a little slower.) So my guess is that AMD will be 20% slower than Intel at the end of the year, and that's not even counting the (potentially quite large) benefit of multithreading. *sigh* Such a shame. If only AMD was executing on Hammer better. Might have to sell some shares eventually. -Tom
