Which laptop is faster . . .

[imported_2x]

A Dell Lattitude with the Pentium M 770 (2.13ghz), 1 gb 533mzh Ram, 60gb 7200rpm drive or
A HP with a P4 650 (3.4ghz), 1 gb 533mhz Ram, 60 gb 5400 rpm drive

Weight and size and battery life are not an issue. Just raw speed.

I think it's the dell, but would like opinions.

Hard to say... what kind of "hard core number crunching" are you doing? Is the program optimized for SSE2/3? Is it heavily dependent on memory bandwidth, or raw CPU speed?

Hmm, hard to say - it's proprietary statistical software for use by a professor who needs to run numbers I am guessing a la seti or something like that. Processing number data similar to SPSS or SAS.

HP P4 will own the Pentium M, the mobile is conserve battery life but at the cost of some CPU preformance.

I believe the P4's FPU is still superior to the PM's, so for number crunching it will be the P4. It should have 800Mhz ram though, not 533.

800mhz ram? where? you mean fsb? 533mhz ram would be ddr2 wouldnt it?

 

[obeseotron]

He means FSB. Pentium M laptops are far more usable and in some areas like games perform extremely well. I don't think the same is true of pure number crunching. Get the P4, but it will be heavier, hotter and get half the battery life.

P4 owns the PM in numeric intensive applications, and it sounds like the P4 is the fit unless you also need graphics ability as well... then it might change the picture some.
