Knowing processor information from Solaris Box

Solaris provides a command called psrinfo which displays information about processors.

For example to know whether your system runs on AMD or Intel processor, run this command with following arguments

bash-3.00# psrinfo -p -v
The physical processor has 1 virtual processor (0)
x86 (GenuineIntel family 15 model 4 step 8 clock 3391 MHz)
Intel(r) Xeon(tm) CPU 3.40GHz


As always, try out man psrinfo for detailed information.
