  • 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.
