Preaching to the choir on MHz...

However, a CPU that is 30% faster than it was last
week is a faster CPU... but you can't cut across architectures. Sure. However, an in-order processor
such as Itanium clocked at 733 MHz with significant
cache miss issues up against a 1.2 GHz seriously out-of-order IA32 CPU... well I don't care how well you
try to sell me on EPIC it ain't cutting it. And yes,
I have been reading Paul's lengthy explanations
at www.realworldtech.com for quite some time. Does that
make me an expert? Certainly not. That's why I have
to cut and paste his critiques if given the chance ;-)

"Basic logic would tell you the E10000 should be 166% faster than the S80 if you only look at the processors."

No.. regarding tpmC there are a number of very good papers
out there , key elements are L2 cache size, latency and
bandwidth... these are issues everyone is aware of
and Compaq/Digital has been studying these areas very
much since 1996 as their Western Research web site notes.

Here is one of the better papers that show how they
are all related.. excellent piece:

research.compaq.com

and it points out why 21364 will be a beast until
21464 comes along to totally dominate.
