Very roughly what's the equivelent performance of both?

ie: A 1.5 GHZ centrino laptop is roughly equivalent to a ___ GHZ Northwood??

Hmm, 2.1GHz I think. That would be the 2166MHz one.

Centrino isn't the CPU name, it's the Pentium-M. Centrino is a package that includes the Pentium-M and a wireless solution.

Pentium-M offers up to 2/3 increased battery life! Unfortunately most manufacturers assume that means they can use a smaller battery. But at least the smaller batter reduces weight.

My 1.4 GHz Pentium-M is faster than my brother's 2.4 GHz Pentium 4 at software 3D rendering. It's equally fast at compiling. But it's slower in other tasks that require high memory bandwidth, although that might also be caused by the slow laptop disk.

Either way, a 1.5 GHz Pentium-M could hardly dissapoint you. Even Dell prefers the 1.7 GHz Pentium-M in their high-end desktop replacement and workstation notebooks instead of the 3 GHz Pentium 4...

My P3@1583 is about equal to a P4 2.0a or Athlon 1900+ or 2000+ . Plus or minus a few percentage points here and there. Wins some looses some.

thanks for the info...

Don't forget the Pentium-M has a 1 MB L2 cache and 32+32 kB L1 cache! The Pentium 3 (Tualatin) has only 512 kB L2 cache and 16+16 kB L1 cache, and Northwood has 512 kB L2 cache and 8 kB L1 data cache and 12 kuops trace cache.

So even though the Pentium-M has a Pentium 3 core, its cache configuration makes it far superiour. So compared to a Pentium 4 it has a much higher efficiency than just the IPC difference with Pentium 3.

Banias is about the same as a P3 core as the Pentium 3 is a Pentium Pro core.

A Centrino with clock rate X is probably enough to make a 1.5X-clocked pentium 4 look small... So the 1.4Ghz P-M should outperform at least a 2.1Ghz P4, and a 1.7Ghz should outperform a 2.5Ghz P4 or so... Roughly speaking. These are great processors! :smile:

i would like to try overclocking one of those to 2-2.5ghz to see how they would perform....

My own beast: Athlon 2700xp+ (oc: 3200xp+ with 200fsb) , Radeon 9800pro (oc: 410/370) , 512mb ddr400. SO MUCH faster than my last computer (pIII 550......)

Yes... And just imagine that a 1.8Ghz Dothan is slated for very early 2004... And it has a full 2MB cache!!! That's got to be one frightening beast.

And next year we'll also be seeing 2.13Ghz Dothans with 533Mhz FSB... not bad, eh? They should match 3.0Ghz P4s very easily! Possibly more... :cool:
