Is the semi conductor industry kind of slow with progress on CPU speed?

CEO of NVidia said eventually GPU speed will be faster than CPU speed. I wonder sometimes, shouldn't we be at 10ghz or more by now with CPU speed or is the semi conductor industry still stuck trying to figure that out because as CPU speed gets faster, so is the amount of space gets thinner and can't... show more CEO of NVidia said eventually GPU speed will be faster than CPU speed. I wonder sometimes, shouldn't we be at 10ghz or more by now with CPU speed or is the semi conductor industry still stuck trying to figure that out because as CPU speed gets faster, so is the amount of space gets thinner and can't squeeze it in? Steve Jobs said something like that one time.
