In one clock cycle, light would be able to travel about 780 micrometers. The real propagation speed of signals on a chip will be substantially less than the speed of light, and it gets slower at smaller feature sizes. This could be tricky. http://en.wikipedia.org/wiki/Interconnect_bottleneck http://en.wikipedia.org/wiki/Interconnect_bottleneck
