That's a really cool analogy - comparing the CPU to a bicycle.

Moving the pedals through one cycle is pretty much the same for all bicycles since they are mostly the same size. That could be directly related to the clock speed since a MHz is a MHz no matter who the chip maker is.

On the other hand, depending on the gearing, you can cover more or less distance, meaning you can complete more or less work. So you could say that the PPC, Intel and AMD chips start off with the same MHz base, but they are geared differently.

Thanks for thinking of that. I'll have to use it in my next hardware class.

BTW - anyone else wondering how Intel is going to explain how the Itanium gets so much more work done than Pentium while it is running at about half the clock speed?
 
The bicycle analogy...

...is an excellent way of explaining. The actual explanation is slightly more complicated (more along the lines of different gears for different tasks, so one chip will win at one thing and another at another thing), but that's basically it. Right now though, G4s only win at Altivec heavy tasks. Compared to a P4/AthlonXP their integer/floating point performance is not that great. Still, Altivec *flattens* SSE, SSE2, MMX, enhanced 3dNOW!, and 3dNOW! (the x86 equivalents to it).
 
slice of bread

they could say that the itanium processes faster because the die is phisically bigger!!! hey a new consumer scale of *judging* which processor is the fastest. Who needs Mhz (Ghz) when we have die size!!
