how to compare the computing ability of pentium M with P4?

[treesmiling]

how about the computing ability of pentium M 770 (2.13Ghz/533FSB/2MB),

pentium M 2.13Ghz=? * P4 2.2G,that means , at the same clock

frequency , the computing ability of Pentium M is equal to how many

multiply the computing ability of P4.

And how to compare core duo (not core 2 duo) with pentium M from the same aspect.

anyone tells me?

thank u!

no.
the menitoned CPUs are so different. The Pentium M outperforms the Pentium 4 so brutaly in every single benchmark known to mankind.

i mean that at the same clock frequency , the computing ability of Pentium M is equal to how many multiply the computing ability of P4.

Hard to say exactly since there are different P4's, but at a guess I'd imagine the pentium M would perform somewhere around 1.4x better clock for clock than the pentium 4

 

[gOJDO]

from 140% to 160%.
the real advantage of Pentium M compared to Pentium 4 is the TDP of the processors. The Pentium M is much more energy efficient than the Pentium 4. Between the mentioned CPUs it is extremly stupid decission to choose Pentium 4.

There's no way to tell without looking at a specific benchmark.

The scaling is also non-linear.

Can you not just leave it as "Pentium M outperforms the Pentium 4 so brutally in every single benchmark known to mankind", like gOJDO said?

thank u! guys above ,
very glad to receive ur help.

I've owned P4 mobile 2GHz(northwood) and now I own K8(lancaster ML34 1.8GHz) & Core (dothan 760 2GHz). I use my notebooks for programming(MS VS 6, .NET & .NET 2, Borland TC++ builder 5&6) graphics (photoshop, corel) and document viewing & presentations (Adobe Acrobat, MS Power Point). The Core architecture outperforms Netburst more than K8. That is my objective opinion based on my own expiriences.

how about the computing ability of core duo (yonah)(not core 2 duo)?

 

[Julian33]

I'd guess that Core is probably about the same as the A64 clock for clock, at about 1.6 times the P4. Core 2 i'd estimate is probably close to double the performance per clock of the P4. Of course, this would be in single threaded apps, since you obviosuly would get greater increases in multi threaded apps with dual core as opposed to single core CPU's
