That is a great point, there is an awful lot of bias in favour of Intel in such reviews.
I was seriously considering getting an 11900K and selling my 10900K which was until I saw it was only going to be 8c16t again, I was seriously expecting it to be 12c / 24t.
And the benchmark performances are all over the place and inconsistent, in some cases Intel take back the single core crown and perform better, in others the 11 series is slower than 10.
Also it looks like Rocket Lake has very little room for overclocking - in fact out of the very few reviews I can find for the 11700K, none of them have overclocking results, simply people that have bought them are upset that they barely overclock at all.
As i'm sure you don't need me to tell you, keep the 10900K, its a better CPU, the 11900K is actually faster in a lot of single threaded workloads but these days that is irrelevant, and it doesn't make it a better gaming CPU, it isn't, in Multi threaded the 10900K is faster, and it uses less power.
