A hybrid.. Well, it's not quite that simple. No CPU is that simple anymore.
There are things like branch prediction where the CPU guesses what the
result of an "if" will be and only later learns if the prediction was
right or not. If it was wrong, it has to undo all the stuff it did, if it's
right, it just won a lot of time. There are parallel execution of several
instructions at once etc. There are floating point arithmetics that execute
on very different speeds on even different x86 chips, depending on the
model etc. You can generalize it like that.

For some things. For others, a G4 at 500 MHz sucks eggs.

The apps are very different when it comes to Photoshop and Freehand. There
are many things completely MISSING from the PC version, which leads me to
believe that they are not at all based on one and the same piece of code
with a couple of #ifdef's. Differences in speed have as much to do with
the code as it has with the chip.
