Can we get an APU with 16 or 32GB of HBM to build tiny PCs? That and an SSD and some IO would make an awesome SFF. Of course do this all at low power so air coo

Can we get an APU with 16 or 32GB of HBM to build tiny PCs? That and an SSD and some IO would make an awesome SFF. Of course do this all at low power so air cooling is possible.

APU with 24 or 32 GB would be really awesome, this would be perfect for a game console (new steam machine?). The extra memory is very useful as the GPU and CPU would be one. Similarly, the M1/M2 Mac mini could, hardware wise, also be a great game console. So we are maybe not that far away.

that would be really great… if AMD had a working software stack that supported consumer (as opposed to: datacenter) APUs. I'm writing this on a machine with a Ryzen APU… and it's pretty much unusable for compute. And that's not a hardware problem (the hardware specs would be nice enough) but AMD not giving a shit about having a working software stack, especially if it doesn't fall into one of the two domains: "gamers" or "datacenter".

  Which APU do you have?

Too expensive. PC OEMs dont even like moderately sized IGPs, as they largely rejected Intel's Iris Broadwell eDRAM chips, Kaby Lake G, and Van Gogh (the Steam Deck chip[1]): [1] https://videocardz.com/newz/amd-mobile-apus-for-2021-2022-detailed-first-navi2-igpu-coming-with-vangogh https://videocardz.com/newz/amd-mobile-apus-for-2021-2022-de...

  I was trying to shop various higher end intel iGPUs. Generally the premiums were so high than a low end Nvidia was much faster AND cheaper. They were somewhat lower power, but it was a pretty narrow space where Intel had the advantage.

    The only IGP-heavy gaming device around these days is basically the Steam Deck :(.

      Not to mention XboxX and PS5, both use flavors of the AMD APU/iGPU. Sad that cheap consoles have better memory systems than any normal AMD/Intel box short of a Xeon, Epyc, or Threadripper.

Sadly AMD/Intel iGPUs (which AMD calls APUs) are limited to 83GB/sec or so, of which you'd be lucky to see 50GB/sec or so. Apple has 100, 200, 400, and 800GB/sec flavors that fit in laptops (100-400), mac mini (100-200GB/sec), or mac studio (400-800GB/sec). Configurations up to 96GB ram are available. Even does low power, air cooling, and pretty quiet. I do wish Arm, AMD, or Intel would do similar. Maybe a future AMD will have a better memory bus, like they one they ship i n the PS5 and XboxX. Or maybe Nvidia will ship a smaller version of the Hopper+Grace that fits in a SFF.
