"an overclocked 7700K would routinely roughly equal the 9900K's frame rates"If that were true, an overclocked 7700K would routinely roughly equal the 9900K's frame rates...(when both are running at/near same clock speeds, ~all core of 4.6-4.7 GHz)
It does not, and particularly in gaming/streaming scenarios (naturally, they are pretty close in 4k gaming, i.e., in massively GPU-limited scenarios).
Several games are doing well on more cores/threads, such as BF1 and BF5 among others...; comparing CPUs that lack SMT/hyperthreading such as the 9700K, however, do seem to indicate that real cores are more important than just thread count, as the 'only' 8 c/8t CPU still smashes in performance...
it would and it does,even at stock most people would call this even,it's exactly 10% behind,the 2700x is farther behind the 9900k than the 7700k is.
This is an extensive multiplayer bench.
Yes of course,doing CPU streaming (like it's 1999) won't be as good as on a CPU with more cores but nobody,certainly not me,argued that.
