Re: "Can you tell us the improvement from going from a PIII to a Xeon in an identical system."

There are no identical systems because Xeon uses Slot2, but I'm nitpicking, they are close enough.

spec.org
spec.org

Dell Xeon Workstations compare as follows to a Dell PIII Workstation @500MHz:

SpecInt95:

Xeon 512K + 5.8%
Xeon 1Meg + 8.3%

SpecFP95:

Xeon 512K + 8.4%
Xeon 1Meg + 13.3%

So I know this is somewhat preliminary, but at first glance it looks as though a Coppermine may very well outperform a 1Meg Xeon. It would seem that if the data holds, the reduced latency of the L2 is a big deal. The on-die data path may also be wider than the 64 bits to the off-die L2 which would help also.

Note to Ali: before you make another dumb post we all know that the Xeon is not intended for the desktop but the SMP environment where the large cache cuts down on bus traffic rather than providing a dramatic performance boost for a single processor system. That's the only way to justify the cost.
