What is the difference in performance, clock for clock?
I want to get an IBM X31 with P-M 1.5G (Banias) for very cheap overseas, but I don't want it to be "obsolete" so soon. If the difference is considerable, I will consider a T42 with P-M 1.7G (Dothan), but it will cost quite a bit more.

Theres definitely an improvement clock for clock, it's not massive though.

There is definitely a significant improvement. Looks like I'll be getting a Dothan.
Thanks guys for your help:

If that small increase in performance matters regardless of the extra cost so much that you call it significant think of the extra benefit from an Athlon 64 in a laptop...
Probably cheaper and faster than a 2ghz Dothan aswell. |

But I don't want to sacrifice battery life at all, so an A64 is out of the question.

You realise your sacrificing battery life with a Dothan, over Banias? :P
Or isn't the difference "significant"? :P I'd go for a Dothan aswell over Banias. But I don't reckon the cost is worth it at the moment for the performance increase. But anyway, each to their own significance.

I was under the impression that clock-for-clock, the Dothan processors offered superior power management.

Actually, compared to the Prescott, the Dothan doesn't suffer the same major heat issues.
Its not only about manufacturing process, its also about architecture as well. Intel did delay the Dothan to resolve some heat issues, and it did quite well. It is said that Dothans run slightly cooler than Banias. Hmmm, let's take a look at Intel's Processor Spec Finder. ![]() To prove that it ain't just one speed grade benefiting, we'll look at 1.4Ghz and 1.7Ghz Pentium-M 1.4Ghz (400Mhz) SL6F5, 0.13 micron, 1 MB 479 pin H-PBGA FC-BGA2 => Thermal Guideline : 22.0W (Banias) SL6F8, 0.13 micron, 1 MB, 478 pin PPGA FC-PGA2 => Thermal Guideline : 22.0W (Banias) SL7F3, 90 nm, 2 MB, 479 pin H-PBGA => Thermal Guideline : 10.0W (Dothan) Pentium-M 1.7Ghz (400Mhz) SL6N9, 0.13 micron, 1 MB, 479 pin H-PBGA FC-BGA2 => Thermal Guideline : 24.5W (Banias) SL6N5, 0.13 micron, 1 MB, 478 pin PPGA FC-PGA2 => Thermal Guideline : 24.5W (Banias) SL7EP, 90 nm, 2 MB 478 pin PPGA => Thermal Guideline : 21.0W (Dothan) Interestingly... Pentium-M 2.0Ghz (400Mhz) SL7EM, 90 nm, 2 MB, 478 pin PPGA => Thermal Guideline : 21.0W (Dothan) |

Ok, thanks for all the info. I've decided I'm getting a T42 with P-M 1.5G (Dothan). Not as expensive as the P-M 1.7G, but I think the extra over the Banias will be worth it as the Banias is already obsolete.
