<< I really can't understand why Michael Dell would even consider the A4, unless there is concern over the volume availability. >> There'll be no compelling reason to go to A4 except price until AMD gets to .13, but at .13 I'd guess the A4 will be substantially better then the tualatin. As it is, the A4 will still be good enough to substantially raise AMD's marketshare, we can probably get to 20% notebook share by the end of the year. << Another possible concern for Dell is that Intel says that they will switch to P4 mobiles, which makes zero sense to me. >> They need to have a competitive laptop on the same process. When p4 and athlon hit .13 process like tualatin, they'll both probably smear the tualatins. Just my thoughts, Doug

> I have come to the conclusion that the Tualatin will be a > better mobile chip than the A4. Keep in mind that the Athlon 4 uses a lot less power than the Athlon MP, as its operating voltage is much lower. So making a comparison based on the Athlon MP power dissipation is not the right thing to do. I don't have the numbers on me, but a quick calculation suggests that the Athlon 4 at 1.20GHz at 1.40v will require just above 31Wtyp. The Tualatin is still better, but not by as much as you would think given the process difference. In addition, SpeedStep is a somewhat lame and primitive means of dropping power. 3DNow! and LongRun are much better (instead of running statically at a lower performance level when power needs to be conserved, the AMD and Transmeta processors vary their power and performance by the current demand of the system, so in "power saving mode", the AMD and Transmeta processors would suffer a much smaller performance penalty while not having to sacrifice too much in terms of power conservation). Additionally, the Athlon 4 is a higher performance processor. Well, it's higher per clock. Tualatin will apparently be outdoing it in straight frequency. Basically, you can arguably say that the Tualatin is better, and you can arguably say that the Athlon 4 is better. Beyond that, the Athlon 4 has, I expect, a strong advantage in pricing (except, allegedly, when Dell is involved). And it's actually out and available (I expect Tualatin to have decent availability, but as of the current moment, the highest speed Intel mobile chip is still the 1.00GHz Coppermine). -JC

Re: Weren't you saying that Tualatin had the same power dissipation as Coppermine? Not quite, since Intel has so far not released enough data to allow for a comparison at similar voltages (they don't seem to have finalized the mobile part's specs yet). The comparisons of the .18 low voltage parts and the .13 parts that ran at similar voltages indicated a similar power consumption. What is clear is that, as processes from both Intel and AMD become more advanced, there seems to be a much smaller percentage reduction in current - an indication that leakage is rising, as was expected from smaller devices.
