The 5 Ghz Project

Here's a 13 page article that explains what is happening. Briefly: Most microprocessors today run at somewhere between 2 and 3 GHz. By supercooling the processor with liquid nitrogen, they were able to roughly double its clock speed (and therefore its processing power). The only thing keeping mainstream chip manufacturers from increasing clock speed is the fact that, right now, a chip running that fast generates too much heat.
