How do you determine what type of CPU socket a linux computer has?

Question

What Linux command/program can I use to tell me what type of CPU socket a Linux desktop has?

I use CPUZ or SIW on windows, and I can use "cat /proc/cpuinfo" on Linux to get the rest of the possessor's information, But it does not tell me which socket the CPU is.

Thanks.

If you have x86info installed you can run it with x86info -a and you will get something like this:

x86info v1.11.  Dave Jones 2001, 2002

Solution 2

This works for me: dmidecode -t processor.

Other types are: bios, system, baseboard, chassis, memory, cache, connector, slot.

Solution 3

What model is the processor? CPU-Z and cat /proc/cpuinfo should say. Once you find the processor type , Google will find you specifications on said processor which does have the socket type.

I like to use a program called screwdriver. :p

...and is ultimately the only reliable means.

Zoredache, I like your style.

It seems "dmidecode -t 4" is more usefull then the "x86info" as it seems "x86info" only knows about older hardware, while dmidecode gives a "Socket Designation" on newer hardware as well.
