Take this WITH a grain of salt or two, but its rumored that AMD intends on implementing SMT4 for Zen3 aka 3 threads per core on desktop and 4 threads per core in Enterprise.
Thus, a 6c chip would give you 18 threads instead of 12, 8c would get you to 24t and 12c would get you to 36. Given that applications are moving more into multi-threaded workloads for gaming and high performance compute, this makes sense. Plus with next-gen consoles from Sony and Microsoft both leveraging Zen2 8c/16t CPUs, this move would make sense as games will scale to 16t more than they will scale to really beefy single core performance. Not to say that the latter wouldn't benefit the former, but overall, Zen2's IPC falling within 5-10% of the 9900K going INTO consoles is massive. That's going to be the baseline performance driver for the next 5-7 years.
So really, it's difference with the 9900K doesn't matter as much as its purported to be. It would make a sizable market impact IF MS went Intel and Sony went AMD. But both these companies are going AMD for CPU and GPU. So keep that in mind when you buy your next CPU. GPU in PC space is relatively platform agnostic. There might be some gains here and there between going all AMD, but not enough to really drink the koolaid deep.
