Pentium M & Pentium 4 Confusion

[OnlyCurious]

My friend has a Pentium M at 1.4ghz (laptop) and Doom 3 runs smoothly on it at high resolution... I'm a little confused... the min requirements says 1.5ghz on Doom3. How are you supposed to compare the speeds of a Pentium M and a Pentium 4. Cuz for newbies like me, when I see Pentium M at 1.4ghz, I picture this really slow ass computer that is out of date now... Can somebody tell me how Pentium M's work and although they are like around 1ghz they are fast as a 3ghz pentium 4 or w/e... I DON'T KNOW, SOMEONE CLEAR UP MY CONFUSION!!!! THNX!

Pentium M's use a 10 stage process, like AMD processors. A 1.4 ghz pentium mobile would have the peformance of lets say, a 2.2GHZ p4.

Their artechture is very alike AMD.

You will need to search for benchmarks to properly be able to compare it to normal CPU's
