Identifying my exact processor model

Likeless · 05-19-2009, 03:11 PM

I need to identify which processor I have from the list on this page:
http://users.erols.com/chare/elec.htm

This is my output from /proc/cpuinfo

Code:

This is the output from lshw:

From this it seems to me that It is a Pentium 4 3.0GHz with a 2MB cache. If I'm right, that narrows it down to 3 from the list:

P4 630
P4 631 - rev. D0
P4 631

Is it possible to identify which one it is from this info? Is there another way?

A third query method more directly for the cpu would be the program cpuid

Sure would be nice if Intel would publish a Model/Family/Stepping Chart.. would make things easier.

Wikipedia shows the 630 as being
http://en.wikipedia.org/wiki/List_of...icroprocessors

Code:

"Prescott 2M" (90 nm)

    * All models support: MMX, SSE, SSE2, SSE3, Hyper-Threading, Intel 64, XD bit (an NX bit implementation)
    * Intel VT supported by: 6x2 e.g. Model 662 and 672
    * Enhanced Intel SpeedStep Technology (EIST) supported by: all except 620.
    * Intel Family 15 Model 4
    * Steppings: N0, R0

So the family and model match for the 630.. unfortunetley they don't list the family and model for the 631 for comparison..

I look at all that with little comprehension, but the last line gives me enough info to clearly identify my processor as the P4 630 as that is the only Prescott model with 2MB cache.

That Wikipedia page also concurs with this conclusion.

Thank you very much for your help!

Hold smokes your cpuid output has MUCH more info than for my piddly old P4 D CPU...

Glad you found that useful
