I believe that the Cray 4 has / was supposed to have 1 GHz GAS cpus.
I have heard of groups that have made ADCs running at 30GHz.

Interesting work is going on in the field of designing  cpus that can
run at 10 to 39 GHz

After all, the commodity market as expemplified by Intel is NOT the
state of the art.
