Until now, the increase in the power of the computers rests primarily on the increase in the number of transistors present in the processors. Things advance since one manages to engrave the chips even more finely and fit in more transistors and thus it is possible to keep the CPU a reasonable size. It is however obvious that as one approaches the physical limit; this is given by the size of the atoms below which one will not be able to go below. Unless a radically different solution is found, one will enter a phase of stagnation. Even though some have started on the optical computer, one is still far from knowing how to build something functional. But the revolution could come from elsewhere, such as the probabilistic processors. Initially, these seem opposed to everything currently believed in data processing. To summarize these probabilistic processors, they allow inaccuracies exchange to an increase in speed. A probabilistic processor manufactured by professor Krishna Palem at the University of Rice is thus 7 times faster than a traditional processor and consumes 30 times less power.
It is currently impossible to consider how to use this processor in the position of a CPU, experiments will be tried using other technologies not requiring perfect precise details, like video and audio processing. The tiny defects would not be perceptible.
It could be just the processor needed by video cards since the 30x reduction in power and heat from the current level (that is the pits) would be very welcome.
