You can't match Mhz/Ghz in a cisc to a risc architecture. It all depends
in the type of applications that you're doing. Reduced Instruction Set
Chips have less overhead in the chip architecture, but have to run the
same operation over multiple times. Complex Intruction Set Chips have
more instructions in their repertiore and therefore can run them fewer
times to get the same result. For the most part you're talking an order
of nanoseconds. The fact is the VLSI (Very Large Scale Integration)
(RISC and CICS) are nearly identical as to speed.  What it really comes
down to is how the developers have coded their bloatware. Not to mention
memory and cacheing of micro-code/machine code.

You're real question should be "Which platform will be able to execute
my software in the quickest most accurate way"  As you might know, you
can get BSD based un*x on a Mac or PC.. You can get MacOS, Win9X/200X/XP
or Linux/SolarisX86 any number of operating systems out there run on any
number of hardware variants.

Sorry but I need to know.  What is the equivalent Intel Pentium 4 speed
of
the:

Mac 800MHz PowerPC G4
Mac 933MHz PowerPC G4
Mac Dual 1GHz PowerPC G4

Or where can I look it up?

Thanks.

Simon
