Dear Dale:

Are you falling into that other trap, that MHz equals performance? A 2.33GHz Throughbred (=Palomino) (assuming dumb shrink), would beat a 3.3GHZ NW (if it has 512K cache and a 166MHZ FSB, it would beat a 4GHz NW). A 2.67GHz Barton (=Palomino) would beat a 3.8GHz NW (if it too has a 512K L2 and 166 FSB, a 4.8GHz NW). However, since the NW 2.2GHz really only NCT (non clock throttled) to 2.6GHz at best, it is debatable if NW will reach 3GHz on 0.13u copper. A 3GHz Clawhammer will have about twice the IPC with lower latency to boot would out run a 4.5GHz NW and a 3GHz Sledgehammer would outrun a 10GHz NW (the ultra high multipliers will start taking a big chunk out of the NW's performance).

I did not see Jerry Sanders ever say that Barton would be slower than NW (link please) although he may have said that Intel so believes, to their horror when it does not pan out (do not confuse clock speed not matching with performance not matching. The former I could believe, but, a 3.3GHz Palomino would beat a 3.8GHz NW more than a 1.67GHz Palomino beat a 2.2GHz NW. Yet both are 533MHz behind)! But if Clawhammer is 50% faster than Barton at same speed and roughly same die size, why not go completely to Clawhammer?
