What comes after we hit the 16nm barrier?
psyklic: I think this question has already been answered -- Moore's Law has been out of play (for processor speed) for some time now. Microprocessor companies are now banking on massive parallelism.One of the most promising new technologies (imo) relies on probabilistic transistors -- which occurs as they get smaller and more current leakage occurs. A perfect example is video decompression, which does not have to be exact. You can get drastic power reduction by doing it probabilistically (for some applications), which is great for mobile devices.
