Is Moore's Law Still Valid?

Moore's Law is about 50 years old and more or less stated that the number of transistors (and processing power) on a CPU would double every two years. It's held its own for most of that time. But it appears that's being tested as more and more transistors are squeezed on to a die.

 

Poll Question: Is Moore's Law Still Valid?

  • If one considers only number of transistors and volume they occupy we miss the quality performance aspects of higher speeds and lower power requirements. I think Moore's Law would be better stated with a measure of operations per second in a defined volume as the measure.

    True. In in fact as performance goes, all machines including mainframes do not use MIPS (millions of instructions per sec), but use MSU (millions of service units) Why service units?

     

    A million service units (MSU) is a measurement of the amount of processing work a computer can perform in one hour. The term is most commonly associated with IBM mainframes. It reflects how IBM rates the machine in terms of charging capacity

    So we see it is the work being done to allow different instruction sets that may exist. RISC vs CISC question affects what an instruction can do...

    I suspect the truth should apply to any MCU or Embedded processor if we want to measure Moore's Law.

    Clem, I'm sorry but MSU is really an IBM box thing but MIPS is the deal, which translates from box to box. Also, there are FFT Butterflies which are a great indication of how your floting point processor is performing, you can use the same test for your GPUs as well

    MIPS takes into account, speed of the overall system. ie, the DRAM, OS, hard drives, and CPU(s).
