Use CPUCHECK at the server console to display per-processor information, including processor number, processor clock speed (MHz), processor ID, processor version and subversion, amount of L1 and L2 cache memory, and current revision number.
cpucheck [processor_number...]
When you run CPUCHECK, the output for a uniprocessor server is similar to the following:
Processor Speed 199 MHZ, CPUID 619:FBFF
Family 6, Model 1, Stepping 9
L1 cache: 16K Bytes, L2 cache: 256K Bytes
Current Revision: D1
To verify information for a particular processor, specify the processor number.
