The architecture is sun4u for all 280R systems. The part numbers you listed are for 1200MHz UltraSPARC III Cu Module, and as long as you use the same CPU speed you can use modules with different part numbers.

If you want to see processor speed you can use either prtdiag or psrinfo -v.

Have you looked at the prtconf command?

prtconf gives the system configuration as : Sun Microsystem sun4u and comes up with a list of system peripherals. nothing about architecture ... –  Andy Jan 25 '10 at 15:40
