Clock speed alone is not a deciding factor. Depending on things like cache size, clock multiplier, pipeline depth, the implementation of micro-ops decoders, the phase of the moon and the branch prediction method, you can get a far more powerful processor at lower clock frequencies.
The main thing the clock speed affects is the power consumption and heat output. A Pentium 4 at 4.0 gHz will perform about as well as two Pentium 4s at 2.0 gHz (assuming they share a front side bus, cache and other bits), but will draw significantly more power and need considerably more cooling.
One thing that clock theoretically affects is latency. A 16-step pipeline (about normal for current-gen) at 2.0 gHz will take a minimum of 1/125000000 of a second to respond to anything. Run it at 4.0 gHz, that goes down to 1/250000000 of a second. This has no appreciable effect on lag, though it used to be somewhat relevant when a "bitchin' awesome" system was built around a 12.5 mHz 20286.
This is why graphics cards tend to be clocked in the low hundred-megahertz, not the low gigahertz. They use massive numbers of cores, each with very low capabilities. They usually draw the same power as a similarly-priced CPU, but have a magnitude better performance, at least in raw number-crunching (one of the bits they sacrifice is interrupt performance, which is essential for running other hardware).
And don't even get started on different ISAs. It is effectively impossible to compare an ARM and an Atom except by benchmarks.
Although I mostly understand all of that, I can't really speculate. I'm not really THAT knowledgeable on the tech, I do know a bit though.

The military already has cpus with more than 1thz, the us army made a super computer using 12,760 ps3's. That means, each ps3 has 8 cores with 3.2ghz on each one ,so thats 25ghz per ps3 multiply that by 12,760 and you get the ps3's super cluster's processing speed.

I'd stop talking rather soon if I were you, it's best not to look like an idiot. With your logic my Q9550 is 11.2Ghz.

So my Q9400 is running at 15.6GHz? Wow!

That means my II 945 is running at 12.6Ghz

Do you count hyper threading with that too ? 29.6GHz FTW. :lol::lol::lol:
Yeah, and my i7 is running at 22,4Ghz!
The PS3 doesn't even use cores, it uses cells, and it's seven cells not eight.

Oh great, my CPU is running at 14 GHz. That can't be safe
32GHz here with my i7
4.52GHz on my P7550

One day I might overclock it so I can play Doom

Accually the PS3s' Cell broadband processor does have 8 cells, but it mostly uses 7 of them. The eighth one is redundent, a "just in case" cell.
