"..please educate us poor Ph.D's. Bottom line is that Intel has 2.0GHz on a 100nm gate, and have demonstrated 3.0 to 3.5 on a nominally 65-70nm gate whereas AMD is stuck at 1.6GHz on a 70nm gate."

Not a problem to give you some education. As it
was "discussed" at length in K6-era with such prominent
Ph.Ds like Yousef and Paul, it was established that
the working frequency of a microprocessor is a product
of gate speed, interconnect delays, _AND_ the pipeline
microarchitecture "thingy" (or the amount of layers
of combinatorial logic between pipeline stage latches).
Shorter pipeline usually have more logic in between,
and therefore is usually slower.
Therefore it is highly mistaken to derive any conclusions
about transistor's technology from the device top operating
frequency alone. Just as reminder, basing on this fallacy,
Ph.D. Yousef has predicted that the introductory speed of
Athlons will not exceed 300Mhz. You know what the
reality was.

"Otherwise be an adult, admit your error, and move on with life."
Being a Ph.D in chemistry does not qualify you to
anything. I strongly advise you to study some basics
of microprocessors design before resorting to your
mockery.
