I don't think games ever needed 'cores'. Games (all apps) need threads and they need to be able to run certain threads uninterrupted, or with the lowest possible latency, to maintain the FPS. Now this is not the thread count that it shows on your CPU box. CPUs run many more of them concurrently, they just don't need to be working in real time all the time. We see with recent CPUs that they cap out in performance with a substantially lower core count than much older ones. There is some gain to be had from core count, but it tends to plateau abruptly, and that happens at or around 8x. Now ofcourse CPUs with more cores can divide the work over more cores. But a faster CPU with a lower core count can and does achieve the same, or better, FPS. For background tasks the same thing occurs. If you have enough cores to move the threads to, having more of them makes no difference. Whereas if you have a faster CPU, you need fewer cores to move threads to because the work's done faster.We already know that games tend to need more and more multicore performance. Cache is also beneficial, but it don't know how it could make up lack of multicore performance, so I wouldn't mix both here. One thing is sure - 7800X3D will lack multicore performance sooner than 13/14th gen i7.
And btw and to be clear: by "13700" and "14700" I meant their whole families, so multiple models differing with letters. Prices of them are always a mess, so man can find e.g. K chip cheaper than KF.
You are right with the heat and it sucks - I know from my experience of owning even worse offenders But I don't know if OP cares.
This is also why clockspeed is so so important a differentiator for CPUs in the gaming space - much more than core count.
