[plug] ia64 linux = P4? & general Q re speed and if anyone has tried it

[John Knight]

>Isn't that meant to be Intel's CISC architecture ???

No. Although intel did make CISC CPUs, that completely stopped at the 
Pentium range of CPUs which use RISC. AMD and IBM still produce CISC based 
processors (CISC -Complex Instruction Set, RISC -Reduced Instruction Set) 
but intel certainly don't make them anymore as they moved into the 
"streamline" market.

Due to the P4 having a more complex instruction pipeline, a similarly 
clocked P3 will beat the P4 in terms of performance due to the P3 having to 
do less on each cycle, but the P4 has the advantage of RDRAM and the ability 
to have a much larger Mhz rating.

The new EPIC architecture tries to do a few things in tandem and therefore 
takes a new approach to things.
