What you're saying is of course true, but in practice most of today's
embedded CPU:s are relatively similar and comparing clock speed should
give you a ballpark figure. DSP:s are another matter, but the SB
hardware spec had that listed separately.

AFAIK a real RISC core is the architecture that comes closest to one
instruction per clock cycle (unless you're going superscalar). I'd
better quit now to keep the thread from imploding under the OT in here
(some of which I take full responsibility for).
