When are things going to get faster?

[Torner]

Back in the 90s it didn't even take 2 years to double CPU speed (200-400mhz, 400-800mhz)
Intel has been around 3ghz for awhile, AMD has been around 2ghz for awhile.
Things definitely haven't doubled for a long time. In 2 years, Intel better be at 6ghz and AMD better be at 4-5ghz
Anyway, anyone know why these barriers haven't been smashed like they have been the last 20 years?
In 10 years, things better be around 600-800ghz
Though by then, I think new technologies may be giving silicon valley a run for its money.

In the 90's it was all single core, now it's dual, quad and god knows what else.

well this is a case of "the sky is not the limit"

Physics has come into play(quantum that is) and about 3 Ghz is a brick wall and it takes too much power and produces too much heat to push past that point. They keep shrinking the die to alleviate the problem, but the only solution is to add more cores and that's only possible when heat and power issues are addressed. All this has been written about for over 2 years now and is common knowledge.
