(Nearly) full tickless operation in 3.10
In mainstream consumer CPUs, maybe the clocks have stabilized (which IS a good thing, we
already waste too much power just to do office work).
Look at the IBM Power6 for some high-clock cores...
Bigger caches ? Where ?

Except that apparently they had a lot of difficulty ramping up the clock..
Plus their CPU does *in order* integer processing which induce a loss of efficiency..
It'd be interesting to have a study which analyse whether going in order for integer
processing to increase the clock really did improve performance or if it was just a marketing
gimmick a la P4.
Power 6 clock high-score and real performance
