I know that it is of course not possible to compare such processors, and that clock frequency doesn't matter much either, but when it is so much more power as a Xscale prosessor has I thought it did matter a little anyway.

Still not close enough to the same architecture. And plus, none of the current emulators (or really any software for that matter) are taking advantage of the Xscale. They are still all written for StrongARM (ARM) processor.

I use the comparison of a car engines max RPM to people's fascination with MHZ.

Thinking that a 300mhz processor has to be twice as fast as a 150mhz processor is like saying that a 6000rpm motor is twice as powerfull as a 3000 rpm motor. Both statements are false.

If motor A is 400HP with a 5000RPM redline
and Motor B is 100HP with a 7000RPM redline
which is faster?

IF CPU a is a 30MIPS processor running at 1000MHZ
and CPU B is a 10MIPS processor running at 1500mhz
which is faster?

The most accurate way to compare different processors is their MIPS or Gigaflop values, not their clock rate. One has nothing to do with the other.

And game systems have multiple co-processors that actually handle the video and audio (like a 3d accelerator in a pc) that have to be emulated by a single CPU. Someone pointed this out earlier and it's a good statement.

The reason it's so much slower is because instead of the program running on hardware it's designed for, every step of the program has to be interpreted and handled in software. It's true that different co-processors take some of the flak off the cpu, but when you try to emulate this you have to emulate all the chips at the same time through software.

That's the main point, one is hardware and one is software.

Look what happens when you play a game with no 3d acceleration card selected, the software and therefore the cpu has to do all the work resulting in much lower framerates.

if anyone here has been keeping up with the brighthand forums, some people have gotten the ipaq 2200 which has ppc 2003 loaded on it... and have reported frame rates of over 30 fps in almost every snes game.... the 2200s processor is very similar to the axim advanced.... maybe we'll see full speed snes emulation on our axims very soon :D
