  • they’ll need to use twice as many chips, which could mean doubling the bus width (one can dream) to 512 bit (ala 5900)

    I misread this part, thinking you implied a bus width increase is necessary.

    For a 512 bit memory bus, AMD would either have to use 1+8 dies if they follow the 7900XTX scheme or have a monolithic behemoth like GB102. The former would have increased power draw but lower manufacturing costs, while the latter is more power efficient and more prone to defects as it’s getting close to the aperture size limit.

    I’d guess nvidia will soon have to switch to chiplet based GPUs. Maybe AMD stopped (for now?) because not their whole product stack was using chiplet based designs so they had way less flexibility with allocation and binning than with ryzen chiplets.











  • Anecdote from my first job (software engineering): New manager wants to know what our team does and how our process and software works. Like, he really really wants to know it!

    Okay, I book a timeslot and prepare some slides and an example; we have a meeting. I go over the high level stuff, getting more and more specific. (Each person on our team was responsible for end-to-end developing bootloaders for embedded HW.) When I got to the SW update process and what bit patterns the memory needs to have and how the packets of data are transmitted, he called off the meeting and I’ve never seen him since.

    I guess, he didn’t want to know THAT much after all.

    As hard as it may be to believe, I can’t eat metaphysics for put a roof above my head with it. Even Plato didn’t sit on perfect abstract chairs or ate abstract apples.

    Here’s another argument I thought of in the meanwhile:

    1. If we accept that the rule of golden mean is universal, then it necessarily applies to itself. Thus, the correct use of the rule is somewhere between the absolutes of not applying it at all and applying it to everything. There are circumstances in which it shouldn’t be used.

    2. If we don’t accept the rule as universally true, then there are circumstances in which it shouldn’t be used.

    QED




  • Depends on the type of distribution too. In some discrete cases there isn’t a mean value. A binary choice for example has no applicability of the golden mean. Like a two party system. If neither represents your values, you can only choose the one that mostly does. Which is not the optimal outcome, just the local maxima.

    The golden mean argument also assumes that there is only one good soulution, where multiple equally good ones can exist too.

    While I agree that most things require a compromise of two extremes, it is also important to acknowledge how they could result in worse outcomes.

    Eg 1: You are sick; the doctor prescribes antibiotics. But you have some concerns about them so you only take it until you feel better.

    But now the pathogen is still there, and it will rebound with new strength. (there’s also a chance it becomes resistant due to selective pressure and its survival)

    Eg 2: Compromise of democracy and authoritarian state. Those countries’ governments tend to be more stable and enduring that are either of the two, but not a middle of the road. This is why the transition from one to the other is usually turbulent as well.
