You can't just compare the numbers like they are the same thing. I'm not too seasoned on the details and differences that make them incomparable, but just ask some of the more knowledgeable devs around here, and they should be able to explain it to you.

Even within the same architecture, Mhz comparisons are not very usefull. A very good example of this was the A64 vs P4. When you start making comparisons across different architecture, you start to fall into a whole hay-stack of different measurements and resulting effects.
There are a few measurements such as Integer and Floating point performance, but even then you have to take into account the application and whether or not you need or will even be able to use the full processing performance.
Often in mobile applications, memory is a bigger bottleneck then the processor. This is mostly due to the lack of cache, which mitigates much of the latency from the main memory bus. The main reason for this is that cache uses up a lot of die space and is powered on even during idle cycles.
Although ARM procs are getting quite powerfull, for today's architectures, X86 procs have more processing power clock for clock. They are also more likely to utilise a larger portion of that processing power over the full spectrum of applications due to better bus systems and fewer bottlenecks.
); but it might reach that high for some things. Definitely Gamecube class ability though. In the end, it's a little difficult to class hardware that differs- so it's all a rough guess.
