No because then there's wouldn't be so many 16C CPUs sold as in fact there is. 8C is better for pure gamers.
The 16 core CPUs sell more than otherwise should because they have the highest clock rate too and are the halo part. AMD puts this together for upsell. Not because most these buyers are using 16C. But these aren't far behind the best gaming parts it is safe to buy more than you need. A 32 core Zen 5C part would be worse so it's not a generally desirable configuration.

In the TPU benchmarking suite, my prediction is that the top Zen 5 SKU will be easily minimum 25% faster in average CPU performance and at least 20% faster in the 720p average gaming performance. Anything above that would be a nice surprise. Compared to the 7950X, of course.

Serious question regarding 3D cache - given the expected changes in Zen5 architecture, do you expect the benefits of the v-cache smaller, larger or about the same as in case of Zen4? Or use case dependent?
Just wondering whether this time around wait for the 3D version.

Especially if you count by revenue, since they are more expensive.
By revenue too.
It's a tiny niche.

Should be a bit smaller since the core copes better with a rickety shack of a memory subsystem.
Z4 is a speed daemon and needs all the cachemem b/w it can muster.

The rest will move on to 32C and beyond, whether from AMD or Intel. Everyone will be happy.
Don't expect it. Mainstream will stay on 16C for performance cores for foreseeable future, and with Intel sticking to 8C setup on perf cores - it will be really hard to break through that ceiling. For Efficiency core configs - that is different discussion.

But we should expect certain shift in DIY form factor, especially with CAMM memory, as I have pointed to many times already.

They're not peasants at all.
Gamers are CPU peasants, and GPU kings.
That's Threadripper area.
No, depends on price and platform. If Intel will provide 8P+32E on desktop it'll be mainstream desktop. Same when AMD follows on AM5/AM6.

The 170W TDP of AM5 just screams that it's ready for more than 16C. It's insane to use it for only 16C, as we've seen with Zen4. The last few 100 Mhz:es consumes an insane amount of TDP for very little perf. That TDP that would be much better spent on more cores. So it's quite obvious that's what AMD has in store. The question is just when it'll happen: Initial Zen5/Zen5c, mid-life Zen5 kicker, or Zen6.

No.
It's for (yes you've guessed it) fatter cores!

More cores is more area.

Fatter cores, yes.

Only temporarily for current CPU generation. They've got 170W to spend on AM5, so while still on 16C they'll use all of that to bump frequency a bit just to compete with Intel. Might as well use what TDP is available. Even if it's technically insane, since the last few 100 Mhz consume waaaay too much TDP for the little additional perf if brings.

The plan for AM5 is of course to use the 170W for more than 16C with later CPU generations (Zen5/6/... or whenever they'll bump the core count on AM5). It's the only thing that makes sense.
