RE:"The high pricing of Tbird and, as you point out, the Gateway 1G system may also be indicators. I'm just a little paranoid because I have a lot riding on this baby. The concrete positives far outweigh the speculative negatives, though." I can appreciate your concerns. I'm going to ride it out for this month and see how the speed binning looks...I'll feel better when T-bird hits a new speed grade... Jim

Re: "I am not totally convinced that Dresden bin splits are as good as classic athlon. The cache yield issue still worries me." With redundancy, the cache yields on 256K are almost assuredly in the high 90s. I have no concern. Regarding binsplits, I don't believe there is enough information to make any real conclusions. However, the 1GHz Tbirds are at 1.75V vs. 1.8V for the Austin 1GHz Athlon parts. All other things being EQUAL, this would indicate approx 3% higher Fmax for the Dresden parts at equal Vcc and identical channel lengths. They also claimed higher speed distributions from the Tbirds. Now, if this means higher speed distributions at identical channel lengths even at the reduced Vcc, this could indicate even more relative performance. The difficulty is in comparing channel lengths. Since even a 50A difference in ave. channel length can result in a 7% difference in Fmax, it is very difficult to accurately assess process differences unless channel length variations can be factored out. I will not make any conclusions at this point but will remain optimistic for future MHz increases. After thinking about it more, I agree with Mani. There is probably little advantage to offer faster parts at this time even it were possible. THE WATSONYOUTH
