You could define an architectural figure of merit as Specmark/Clock freq.

A higher value indicates that this architecture gets more performance for the
same clock frequency.  I calculate:


Prism:	.80
MIPS:	.56-.67
HP-PA:	.63
SPARC:	.45
88100:	.39-41
68030:	.09


This seems to clearly show the advantage of RISC over 68K type machines.  I
think it also seems to show the disadvantage of register windows, since
PRISM, MIPS, and PA don't have them and SPARC and 88K have them.
