You can obtain hardware statistics by looking at the file /proc/cpuinfo.
You can then cross-reference this against Intel's P3 Spec information
page found at:
http://developer.intel.com/support/processors/pentiumiii
/proc/cpuinfo already tells us that it's a 1Ghz Coppermine P3 with a
256kb L2 cache size, but you can cross reference some more info. The
Intel CPUID is composed of three numbers: family, model, and stepping.
So in this case the family is 6, the model is 8, and the stepping is 10,
so you can lookup on Intel's website the information for a CPUID
stepping of 068A which referenced against a 1GHz P3 processor on that
page shows it must be one of the following two processors:
SL5DV/SL52R SL52R cD0 068A 256K 75 29.0 2,3,5,9
SL5FQ/SL5B3 SL5B3 cD0 068A 256K 75 29.0 3,5,9,14
The only difference between these two are the packaging: the first is
FCPGA form factor, and the second is FCPGA2.
This processor runs at a system bus of 133MHz, and has a full-speed
(133 MHz) 256KB L2 cache with a 32KB L1 cache. The L2 cache bus is 256 bits wide.
If you care about manufacturing specs: it's a 0.18 micron chip of
approximately 106mm2 die size with a 28 million transistor count.
