The war of CPUs…
Where are we going to by next year? How much power do you think are we going to reach by 2003?
I bet 5GHs! And again, a completely new technology! ”What do you think?
The war of CPUs…

Well, I just read that Intel's got a new thang going on with their 5 atoms thick conducters.. man, this is like, nano-technology.. Wiait 'till they start using 1 atom thick wiring... That'll be like ultimate.. and we're only 4 atoms away. Wow, sounds like sci-fi to me. 
I'm not sure if 1 atom, has the energy to bond tho.. maybe the smallest possible is 2 atoms? Cuz you don't want the atoms to just suddenly burst away as soon as you process something.... and if they fly away fast enough, you've got an atom bomb or something.
Not that's a CPU war!!

ya.. Since a CPU is like a bunch of wiring, and essentially a circuit, the less amount of energy needed to send electric signals through the wires = faster CPU.
The thing is, the more material a burst ofelectricity has to travel through, the more lossy it gets (because of resistance). So to get around that, you use less material, and make smaller circuits, so that the electricity can burst through it without much loss. Just like in music! a 10 meter audio cable is going to be noisy whereas a 5 meter one is nearly noise free. But with CPUs, it's 10 atoms thick, versus 5 atoms thick.. what a small scale...
And now we've got curcuits so thin, it's only 5 atoms thick.

Apparently the theoretical limit is 2 atoms thick, and then they have to find a new approach altogether. One of the more exciting alternatives currently being investigated is quantum computing. A quantum processor would utilise the typical on and off states, as well as a bizarre third state which is both off and on at the same time! Don't ask me how, but this would allow a device to execute millions of instructions simultaneously.
Imagine a quantum Pulsar!

2 atoms is the theoretical limit, but pretty much impossible. 1 atom out of place and the whole thing is screwed up, so I don't think we'll ever see one . . . we'll get a whole new technology before then. With 4 atoms you can still allow for a bit of leeway in the design.
I seem to remember another problem is actually the quantum factor you get to with a single atom . . . something unpredictable about it in normal semi-conductors.
