dryriver writes: We all know that CPUs and GPUs and other electronic chips get a little faster with each generation produced. But one thing never seems to happen -- a CPU/GPU manufacturer suddenly announcing a next generation chip that is, say, 4-8 times faster than the fastest model they had 2 years ago. There are moderate leaps forward all the time, but seemingly never a HUGE leap forward due to, say, someone clever in R&D discovering a much faster way to process computing instructions. Is this because huge leaps forward in computing power are technically or physically impossible/improbable? Or is nobody in R&D looking for that huge leap forward, and rather focused on delivering a moderate leap forward every 2 years? Maybe striving for that "rare huge leap forward in computing power" is simply too expensive for chip manufacturers? Precisely what is the reason that there is never a next-gen CPU or GPU that is, say, advertised as being 16 times faster than the one that came 2 years before it due to some major breakthrough in chip engineering and manufacturing?
