Of course :

cpu0 at mainbus0: SUNW,UltraSPARC-III+ @ 900 MHz, UPA id 0
cpu0: system tick frequency 5 MHz
cpu0: 32K instruction (32 b/l), 64K data (32 b/l), 8192K external (512 
b/l)
cpu1 at mainbus0: SUNW,UltraSPARC-III+ @ 900 MHz, UPA id 1
cpu1: system tick frequency 5 MHz
cpu1: 32K instruction (32 b/l), 64K data (32 b/l), 8192K external (512 
b/l)
