Does anyone know of a review comparing P4 to P4M?

[jcmuff]

I'm trying to find where the P4 and the P4Mobile Centrino processor are comparable since the 2.8 gig P4 are about the same price as the 1.4Gig Centrino. Do they perform the same or what?

Thanks

Why like comparing two different things? They're designed for different purposes. Put a P4 in a laptop and you wouldn't get very good battery life.

indeed a full P4 would drain a battery like it was watter or something. I would say the centrino is as expensive because its a mobile product. Not sure if you looked at notebooks before but they allways are a bit more pricey then standard desktops.

compares the pentium-m to the pentium 4 2.66

I have the real thing here right now...My work laptop a centrino 1.5ghz and a p4 desktop PC.....I ran some test awhile back and I can say the performance of the P4 centrino is pathetic...I mainly say that cause the marketing BS was that is was as fast as a 2.2ghz p4...In what??? I tested it and found that to be the case in just a few isolated apps...probably ones that liked the 1mb of l2 cache..Otherwise FH times BLow.....MOst all high cpu intensive apps this thing runs like a 1.5-1.7ghz p4.....Only in some select multimedia things did it perform equal to my 2.4b I downclock to 2ghz....


EDIT: Actually jaring my memory a bit the FH times wer decent and things like winzip or winrar compression was quite decent as well...This are some of the areas where it did well compared to a 2ghz cpu.....

Yout want to compare a P4 to a Pentium M.... (NOT Pentium 4 M...thats a diff discussion)

Edit your post and title....

I have a P4M 2.4 laptop with a 15.4 inch screen...

Battery lasts me around 2.5 - 3 hrs.... with speedstep OFF.

With speedstep on, and screen slightly dimmed.... i have worked for 3.5 hrs. There was still a little juice left...

You are getting your wires crossed.

There are 3 different Intel processors you could find in a notebook.

P4 - exactly the same as the ones you'll find in a desktop
P4m - the same as a desktop, but with SpeedStep and slightly lower power consumption
P-M - The ones you see in "Centrino" packages. These are a totally different processor, that is faster than the P4 at the same clock speed, has low power usage, also known as the Banias

Go look at the article that ElFenix linked.l
