I currently have a sony vaio with a p4 1.5ghz processor, and im wondering how it compares to the pentium M processors in the laptops of today. I don't want to spend 1000-1500 for a laptop with the same performance as my pc of 3-4 years. Somebody please explain.

There have been a lot of threads about this before, I'll try to answer as best as I can. Pentium M chips use a different chipset than the Pentium 4 chips. There is a performance gain, because the Pentium M chip is optimized better. From what I've read, you can expect a Pentium M 1.5 Ghz chip to operate comparable to a Pentium 4 3Ghz chip.

It's hard to compare them. The Pentium Ms are good mobile chips. My 2ghz Pentium M performs faster than my athlon 64 3000+. If you get a 1.6 GHz Pentium M you'll be getting (my guess) around 2.6 ghz of P4 performance, I could be wrong abot this.

EDIT: Lighwieight, seems a little high to compare a 1.6 PM to a 3.0 P4

I have a Pentium M 1.5GHz Banias, and my brother has a Pentium M 1.86GHz Dothan.
I would say a 1.5GHz P-M scale nicely with a 2.5GHz Northwood while the 1.86GHz performs close enough to a 3.0GHz Pres
cott.
I read somewhere that a overclock 2.5GHz P-M Dothan > FX-55 in gaming.

My 2.0GHz (533FSB) Dothan is roughly 3-10% slower than my Winchester A64 3200+ at stock. Not a bad chip, especially considering the amount of power it uses ;) .
