I just read the technology review concerning the performance of a "modern" computer matched against a 2007 computer. Although clock speed is not increasing much if at all, performance is. Multi-core, more onboard (chip) memory, better & faster communcation buses and memory seem to be the low haning fruit. Also, with the advent of multi-gpu graphics cards, new possibilities exist in performance increase not just in video, but actual parallel computations being off loaded from CPU to GPU.

I guess Moore's law is general purpose... I always thought it referred to clock speed. However, when the low hanging fruit is picked, what next? Do we go back to speed increasing wars? Will we ever see clock speeds in the 4-5Ghz range and beyond?

What I was trying to get at is this: Is Moore's Law a self fulfilling prophecy? If somone discovered a technique or process that significantly outpaced Moore's Law, would they be tempted to hold back and release it bit by bit under the cover of the Law?

Why have clock speeds not increased?

Well current silicon chips are capable of 4-5GHz, but heat becomes the limiting factor. When technology arrives at future chips being capable of being produced by way of superior heat resistent materials the speed barriers of today will fade away. For example say a fiber optics based procerssor. A CPU capabe of running at 10,000GHz. ;)
