Tony, "This is normal. Are you going to tell me that AMD chips have just one clock for all the logic on chip? I don't think so."
I am not going to tell you so. But I am going to ask
you why Intel does not use the "double-pumped ALU"
frequency as the marketed CPU frequency, and say
to public that their top P4 is "running at 4GHz"?
I can tell you why. Because the 4GHz chip area would be
ridiculously small to make this claim reasonable for
general public, probably much less than a square millimeter.
Now, how big is the 2GHz area, Tony?
There are indications that every other part of P4 is
running at half frequency, 1GHz max - caches, decoders,
everything. You can look at the thermal image of P4,
intel.com
and remember that the temperature tends to spread out,
so the actual high-frequency area may be much-much smaller.
In short, all this frequency deal is just marketing,
it has the same level of justification as AMD
performance rating.
