Prtdiag
Solaris offers the prtdiag util to get CPU information of the running platform. This command is runnable by non-root users.
/usr/platform/`uname -i`/sbin/prtdiag or /usr/sbin/prtdiag
Here's some examples

psrinfo
psrinfo can give you more details about individual processors. In Solaris it's possible to disable processors while the machine is running, though I don't see any purpose for this in practice.
<geshi> /usr/sbin/psrinfo -v Status of virtual processor 0 as of: 10/20/2009 10:37:16
on-line since 07/11/2009 14:27:04.
The i386 processor operates at 2793 MHz,
and has an i387 compatible floating point processor.

prtconf
prtconf can tell you how much memory is installed, as well as what devices are on the system bus.
<geshi> $ prtconf | head System Configuration: Sun Microsystems i86pc Memory size: 65536 Megabytes System Peripherals (Software Nodes):

isainfo
isainfo can quickly tell you if you are running on a 64 bit CPU and if you are using a 64 bit kernel. <geshi> $ isainfo -bv 64-bit amd64 applications
