Hi,

I see custom builds for P4 with SSE2, etc however I have no idea what any of that means! I just looked at the Intel website but it doesn't tell me if my CPU has these features, etc.

Is there any software that will tell me what my CPU supports and doesn't support?

I have a Pentium 4-m (2500Mhz).

Thanks also :)

If you're running the Linux operating system, you can type
Code: Select all
cat /proc/cpuid
in a terminal and you should get some useful information.

I use CPU-Z for this purpose. You can download it from http://www.cpuid.com/cpuz.php

Alternatively there is WCPUID [http://www.h-oda.com/] or SiSoft Sandra [http://www.sisoftware.net/]

For Red Hat, it is:
Code: Select all
cat /proc/cpuinfo


as mjt suggests, cpu-z is a nice little program for Windows. :)
Kubuntu 8.04 (kernel 2.6.24-25-generic) / KDE 3.5.10
CentOS 4.8 (kernel 2.6.9-78.0.22.ELsmp) / KDE 3.5.10
Mac OS X 10.6.1 (Snow Leopard) / iPhone 3GS (32GB black)

Oops! That was a typographical error on my part. I meant to type what daihard typed. All apologies.

This gets asked a lot, do you think we could get a sticky thread about "unofficial" builds that list which processors support which Instruction sets?

This page has a nice generic chart, that could be useful for newbies:

http://www.tommesani.com/InstructionSetCPU.html

However, there are probably differences and variances that don't follow that chart exactly.

A sticky FAQ thread with the jargon, unoffical vs. official, nightly vs. release, trunk vs. branch, gcc vs. msvc (win32), optimization, and etc. information would be nice. I'll probably compile some sort of informational thread sometime soon, if no one else beats me to it. I think I covered a lot of the bases with that little list I just came up with.
