Re: There is only one listing for the 2GHz Dothan at Pricewatch whereas the A64 3700+ has 12.

LOL, and this is a valid comparison - why? Athlon 64 is a desktop chip, and the size of the DIY desktop market is huge. Comparatively, the size of the DIY mobile market is nil. It would probably be a lot larger of Dothan compatible motherboards were on the market, but so far, this is not a reality. Might as well compare how many Geode processors are on Pricewatch.

Re: And those emperical test show that A64 3700+ doesn't use anywhere near the family 89W TDP. More like 40W at full load (the two system benchmarks work out to be 44W for the 3800+ and 34W for the 3400+). So its not 4 times the power. Dothan probably uses 25-30W at full load (with NB), so its probably between 33% and 60% more.

Again, your level of BS never fails to amaze me. If you test a large number of Athlon 64 chips, you will see a range of power dissipations at full load, and the reason is because no two chips dissipate the same amount of leakage. AMD puts their TDP at 89W to account for higher leakage parts at the highest bin, so yes, many will probably dissipate less. OTOH, Intel does the same thing, and you'll find very few Dothan chips that dissipate 21W - it will be more like 15-20W. Athlon 64 is a 130nm chip, so I would expect leakage levels to have a tighter range. The 2.4GHz parts are going to be closer to 89W, but many may only dissipate 75-80W, which is still >4x the power of Dothan.

Re: Dothan can't compete against Athlon 64 in the DTR segment. It doesn't have the performance.

That's the funny thing about benchmarks - you can always argue that the testing methodology could be improved and invalidate any results you want. The problem here is that I already offered results, and you posted some of your own. Then I showed that Dothan was still within 5% of the fastest Athlon 64 you posted, and now you have nothing to counter it other than trying once again to invalidate the results. Sorry, Peter, but you can't invalidate all the results, simply because you don't like the outcome.

Face it, Dothan can't compete against Athlon 64 in the DTR segment.

I think you will be rudely suprised at the combined effect of
increasing Dothan's FSB speed to 533 MHz and connecting
it to a chipset with twice the memory bandwidth as the
existing one.
