So far they managed to get faster each 2 years about 2 times. Overall seen even more than that. So many things can get improved IPC can get improved. caches. Prediction algorithms. All very hard to improve but they will improve all bit by bit. when hardware gets very tiny then i love to see 32 cpu's at a single processor-die :) >are limited by the size of the atom and other factors such as conductivity which >are controlled by the laws of physics.
