How long until we can buy germanium or gallium arsenide chips with switching rates/clock speeds in the hundreds of gigahertz or low terahertz? My (probably wrong) understanding is that this is feasible now but researchers are still developing efficient and scalable manufacturing processes.
- dom0 10y agoThis isn't really feasible due to the limited propagation speed of em-waves (ie. electronic signals). I mean, sure, it's probably possible to get to, say, 50 or 100 GHz with very deep pipelines (ie. only limited propagation of signals in each cycle), but we've already seen 15 years ago that deep pipelines basically don't work for general purpose computing. Additionally the frequency-dependent losses are unlikely to fundamentally change.
