Next-gen AMD CPUs could feature up to 32 cores per die
  • The c variants of zen are for cloud and are more compact variants of the full zen 5 cores, they generally want as many cores in as compact a format as possible.

    We might see 5c show up in SoCs (like the chip in a hypothetical steam deck 2) as well because they want their chips to be as small as possible so they can price their devices as competitively as possible. I don't think we will see those go up to 32 cores however as there is indeed no need for that many cores on consumer chips.

  • Not quite an e-core but the goal is the same: Make more efficient use of the available die space by packing in more, slower cores.

    The difference is that Intel's e-cores achieve this by having a different architecture and support less features than their p-cores. E-cores for example do not support multi threading. E-cores are about 1/4 the size of a o-core.

    AMD's 4c cores support the same features and have the same IPC as full zen 4 cores but operate at a lower clock speed. This reduces thermal output of the core, allowing them to pack in the circuitry much more densely.

    Undoubtedly Intel's e-cores take advantage of this effect as well and they are in fact quite a bit smaller than 4c: a 4c core is about 1/2 the size of a zen 4 core. The advantage of AMD's approach is that having the cores be the same simplifies the software side of things.

  • Review of modern terrain rendering/LOD methods?
  • I wish I had what you are searching for, I would be very interested in this as well.All I have are bits and pieces you may or may not already be familiar with.

    SIGGRAPH presentations are generally a pretty good resource. This one about UE5 Nanite has some interesting nuggets: https://advances.realtimerendering.com/s2021/Karis_Nanite_SIGGRAPH_Advances_2021_final.pdf To get an overview of the field as a whole you will probably have to dive into the references and see what people are citing. Apparently this one was pretty influential? https://advances.realtimerendering.com/s2015/aaltonenhaar_siggraph2015_combined_final_footer_220dpi.pdf

    Would love to hear what you have found yourself.

  • Lemmy is popular nowadays, yet is losing its active users
  • I'm very interested to see where it settles. It should give in indication of what percentage of people are able/willing to use lemmy in it's current state.

    The fediverse is such a cool project but it can be pretty rough from a usability standpoint.
