Anandtech did a review of a dothan with the asus adapter, also overclocked it a bit. Yes it may score in some tests, but it's of no use for desktop PCs, it's a mobile CPU. Also it's 32 bit only.
Couple of days ago I read about 64 bit prime95 - the programmer said there is almost 100% improvement on an A64 and about 8% on iAMD64 Prescott. Intel just don't have all the physical registers I guess.
Well what is superPi could also scale twice when becoming 64 bit? If the WR for an FX is 22sec - that means about 11. But I'm not sure superPi would benefit from extra registers, as far as I know it's only about calculations, and 64bit calculations may take more than 32bit due to the better precision 64bit has.
But I say again - the fact that a dothan scores well in superPI may mean something in this forum with like 16000 users, but that’s less that 0.0001% of the people using PCs. I agree dothan architecture is better that P4's, simply coz P4 sucks from the very beginning. And what is the dothan - an upgraded PIII. I still wonder why intel is not dumping the P4 and going for better high clocked dothans...
Can't remember exactly but acording to anand for desktop use dothan is no better clock per clock to an A64. For workstation performance a 2Ghz dothan is lacking about 30% behing a 2Ghz A64, in audio video encoding processors are equal, the same goes for gaming, dothan is good in business performance but how many bussiness man will get a LN2 cooled PC for using MS WORD.
And once again dothans are not 64 bit, they cannot match an A64 in real world performance, nor in price/performance ratio. Maybe a new desktop version revison will improve that but intel are going for PentuimD (I still can't see the Difference btwn pentium4 and pentiumD, maybe intel thinks p4 sucks as a name)
