Jim,

Can the fpu run at one speed and the integer run at another for instance? Or is the core speed the core speed?

Speaking of L2 speeds...why can't someone run the l2 in excess of the core clock speed?


There is no particular reason why the fpu and integer units need to run at the same speed. In fact, most processors have the ability to run the fpu at 0 MHz when not in use.

I can't think of any reason why you would want to run the L2 faster than the core. The core can only absorb data so fast, and the caches need to be balanced to optimize the relationship.
