  • This outlines several issues, a key one is outbidding apple for wafer alloc on leading processes. They primarily sell such high margin products that I suppose they can go full send on huge dies with no sweat. Similarly, the 4090’s asking price was likely directly related to it’s production cost. A chunky boy with a huge l2$.

    I like the way Mike Clark frames challenges in semi eng as a balancing act between area, power, freq and performance (IPC); like a chip that’s twice as fast but twice the size of its predecessor is not considered progress.

    I wish ultra-efficient giga dies were more feasible but it’s kind of rough when TSMC has been unmatched for so long. I gather Intel’s diverting focus in 18A, and I hope that turns out well for them.

    I’m not sure that arm as an ISA (or even RISC) is inherently more efficient than CISC today, particularly when we look at Qualcomm’s latest efforts in notebooks, more that Apple have extremely proficient designers and benefit from vertical integration.






  • I’ve been lucky enough to dumb guy my fedora install since 28, and it’s been pretty decent to me. Granted I’m not using nvidia graphics, and I feel like that could throw a big spanner in the works for regular users. It’s a big enough leap getting into the mindset of installing software from Distro repos rather than directly from the vendor.

    I hope the newer nv open kernel modules don’t stay out of tree. Also hope that NVK will give users the ability to just plug and play with mesa drivers in the future.



  • What I was alluding to with regards to idle mclk behaviour is that there are two factors at play: vertical balanking interval (intrinsic to available display modes for each physical monitor) and combined display bandwidth (cumulative of all connected displays to the adapter).

    Your mclk will idle high with ‘incompatible’ VBIs, and it’ll also idle high to sustain a lot of display throughput.

    This can be observed regardless of GFX vendor, though symptoms may vary somewhat between them. I suppose it could be considered a limitation of GDDR (the same behaviour was never really observed on HBM GPUs like the Vega 64 or Radeon VII)

    That said, friends of mine with nvidia gpus have fixed various multi-display specific issues using nvidia profile inspector
