    Modern Standby - Mature?

    Posted: 15 Dec 2020 02:30 PM PST

    Just curious what people's experiences have been. Do you think Modern Standby (S0 Low Power) is mature enough? Seems like the industry is headed towards it being a standard with more and more models popping up with it.

    Is my processor speed any good?

    Posted: 16 Dec 2020 02:12 AM PST

    So it's a Ryzen 5 3550H and it runs at 2100 MHz, how fast is that on a scale of 1-10?

    If I'm totally in the wrong place to be asking this kind of question give me abuse and tell me to get f'd lol.

    [AHOC] DDR4 5500 feat. Crucial Ballistix RAM, MSI B550 Unify X and a Ryzen 4750G

    How can components have cycle lengths (1/clockrate) that are shorter than the time it takes light to traverse the component? RAM in particular.

    Posted: 15 Dec 2020 03:59 AM PST

    Light takes 500ps to travel 15cm, roughly the length of a ram stick, yet many ram sticks (including the ones in the computer I'm posting this from) have clock rates so high that a single cycle is significantly less time than that.

    How is this possible? To truly be "random access" you'd need to able to access any part of the memory on any clock cycle, so is that just not quite true or is there something else going on?

    Apologies if this is not the place for this question. It's more of a computer architecture question but r/computerarchitecture is tiny, dead, and full of schoolwork questions.

    Alternatively, where would be a better place to ask/where would be a good place to read about this?

    Thanks!

    x86 Micro ops and Rosetta 2

    Posted: 15 Dec 2020 04:03 AM PST

    Modern x86 cpus have a frontend to translate the x86 instructions to micro operations. I've been wondering if Apple's Rosetta 2 compatibility layer can be seen as a software implementation for an x86 cpu's frontend. If Rosetta could be seen in such a way then surely a hardware implementation would be even faster.

    Would it make sense for AMD or Intel to design an x86 cpu where the micro ops would be ARM or RISC-V instructions? They would have to design the core itself once and could sell CPU's with and without an x86 frontend. Or are the micro ops specifically designed for x86 instructions which would make moving to a different general purpuse instruction set illogical.
