    Is the amount of transistors and Ghz what determines the flops it will achieve? I was reading an article that they developed a 1nm CPU as an experiment,currently the core i7 is 32 nm and can achieve 140 gflops when overclocked to 4.2Ghz I think. So does that mean that the max flops a CPU will ever achieve unless going to 3D is going to be around 5-7 teraflops depending on how much you overclock it.

    Number/size doesn't... efficiency and pure technological design determine flops.

    several things determine FLOPS but Ghz of course has alot to do with it along with parallel processing

    So its really Transistors+speed+cores= Flops ?

    It's transistor size only. Theoretically we can have infinite flops with just a few transistors but they have to be infinitely close to each other.

    In reality the speed of electromagnetic radiation is ~300 000km/s in vacuum and slower in wire. So the more distant the transistors are, the more time is wasted in signal travel. This is the reason why the CPUs are getting smaller and not larger; the engineers are trying to reduce the length of the paths.

    Quantum units are hyped as the next gen computing because they are very small and thus stacks thereof can occupy a very small space, immensly decreasing the length of all travel paths.

    get rid of current and use photons

    i want a bajillion petaFlops per nanosecond for my gaming box
