  • 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.









  • 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












  • Up until relatively recently, it was great to see that Vulkan and DX12 were in a practically even split.

    Still great to see that some of the best talent in terms of visual fideltiy showcases Vulkan, like rdr2 (originally defaulted to dx12, now vulkan), doom eternal and so on. Fully expect the next GTA to.

    stadia was derp but it forced interested publishers to get acquainted with vk. I think it ended up doing more good for the industry in the end as a failure, rather than harm by succeeding and locking subscribers into such a restrictive game “ownership” paradigm.
