Pentium M help

Does anyone know if I bought a Pentium M 1.7Ghz (400fsb) Dothan (2MB cache) would it be faster than a Pentium 4 3.0ghz prescott?

I don't believe what some people say about, "ohh, a pentium m is twice as fast as its Mhz rating because of its 2mb of cache".... i've heard it a million times from everybody but

I don't believe this because of 1) doubling the prescott's cache didn't help so much as to do anything anywhere near doubling the performance. 2) i read the pentium-3 based architecture, shortened pipeline etc. is responsible for the pentium m's speed.

so, would the 1.7 P-M be faster than the 3.0 P-4?

  1. Depends on the Task. If it's gaming there would probably be a close tie. When it comes to video encoding the Pentium 4 would make an easy victory.

    But if you take power consumption into the calculation the Pentium M would win in everything.

    Like you said, the cache is not the difference. The difference is in the architecture, shortened pipelines, higher IPCs, etc.
