Difference between Pentium® 4/Pentium® M

[Weider]

Hi I'm looking for a Laptop for AutoCAD, 3d studio MAx and Photoshop. I need a good processor. Today, on Intel, I see these 4 choices.

-Intel® Pentium® M Processor
-Mobile Intel® Pentium® 4 Processor Hyper-Threading
-Mobile Intel® Pentium® 4 Processor
-Mobile Intel® Pentium® 4 Processor-M

On Intel's Website, there are still only some benchmarks:

-Mobile Intel® Pentium® 4 Processor - M 2.60 GHz
as fast as
-Intel® Pentium® M Processor 1.70 GHz

-Mobile Intel® Pentium® 4 Processor - M 2.40 GHz =
as fast as
-Intel® Pentium® M Processor 1.60 GHz

According to GAMEPC:
its peak clock speed of 2.0 GHz, the Pentium-M 755 processor is putting up performance numbers which would be comparable to a 2.8 or 3.0 GHz Pentium 4 processor

I heard too a Mobile is 2x faster than a Pentium 4. Is it true?

Thanks for all replies!!

I'm not exactly familiar with the power of the P-M on those apps, but it's generally a bit faster than the P4 3.0GHz or A64 3000+. It does better in an overclocked state, but you won't be doing that.

An A64 3400+ would be a more powerfull choice, but it would draw around 2x the power. A P4 would draw around 4x the power. This is significant to the battery life and heat output.

In my opinion you probably don't need all the power of the 755 for those programs anyway, so you might be more pleased with it simply because of it's lower power consumption.

If u ever plan to use the machine on the battery get nothing other than a P-M. I just ordered a Dell system with a pentium M and i cant w ait to get it

Clock for clock the P-M is probably 2x as fast as the P4, that is to say a 1.6Ghz P-M would be 2x as fast as a 1.6Ghz P4(or at least nearly twice as fast).
The normal version of the P-M uses just under 30w I think, which is a lot less power than the Athlon64 (50w+ for the .9nm versions) and the P4 Prescott (100w+!!!).
This is for a laptop yes?

Jammydodger: yes it's for a laptop.

About the Battery, I won't use thm a lot. I need a laptop for job, university, home, etc. so most of time, I'll use the AC adapter for it. I'll buy a good battery though, something like 80 WHr 9-cell Lithium Ion.

I was looking for one in Canada. So Dell, Toshiba, SOny, HP, COmpaq, IBM, Acer, Futjitsu are the most popular here.

Get an IBM Thinkpad based on Pentium M
