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.

This is to be expected. The question now is where will it stabilize amd will it start growing again after?

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.
