Not sure why this article on a 10900K is relevant to any but a smidgen of gamers, except maybe those easily parted with their money. How many actually have a 10+ physical core system?
Looking at steam survey (link below) fully 94.9% of all gamers on steam have between 1 and 6 physical CPUs. 4.8% have 8 CPUs, and after that you are talking about really negligible (far less than 1%) numbers.
We've also got plenty of evidence that adding cores beyond 4 has little impact on games - at 4 cores IPC, RAM speed, and clock speed become king (see all of the 3300X reviews, and the i3-9350K reviews back in Dec).
I am a lot more interested to see the i5-10400F, 10500, 10600, and 10700 benchmarks on the Z490 chipset. Those all now support (much) higher speed DDR4, have hyper threading, higher clock speeds, and changes to turbo boost to pick the two best chips on the die for boosting.
