Linux – How to understand cpu family/model/stepping fields in /proc/cpuinfo

cpulinux

I have following in cpuinfo:

processor   : 0
vendor_id   : AuthenticAMD
cpu family  : 15
model       : 107
model name  : AMD Athlon(tm) 64 X2 Dual Core Processor 5600+
stepping    : 2

According to Wikipedia page there are two kinds of 5600+ — one of 90nm technology, another of 65nm. How can I understand which one I have? There seem to be no direct correspondence between contents of cpuinfo and info on Wikipedia page.

AMD site seems to use some other naming scheme for processors too.

How can I map values of family, model and stepping from cpuinfo to the data available on Wikipedia/AMD?

Best Answer

This page suggest that the cpuid tool may be able to list more in-depth details of your cpu.

One of the lines it lists as an output is

(simple synth) = AMD Dual Core Opteron (Italy/Egypt JH-E1), 940-pin, 90nm

So I'd either try that tool or have a look for it in whatever package manager your version of Linux uses.
