Gopher, <So what proportion of a processor has to use the external clock for it to be considered running at that speed? With the P4, Intel have established that you can run parts of the processor slower than the external clock and still claim that external clock as the speed.>

If you haven't noticed, the bus clusters of both Intel's and AMD's CPUs do not run any faster than 133 MHz. Your point is moot.

<What is to stop AMD clocking a little internal divider at 3 GHz and drive the CPU off the resulting 1.5 GHz signal? I don't see that would be "resorting to a level of deceit". It would simply be illustrating that to judge a processor by external clock speed is meaningless and it would force Intel to admit it.>

No, it would then force Intel to advertise the Pentium 4 at the speed which the double-pumped ALU runs, i.e. twice the frequency of the main clock. Then you're back to square one.
