Ah I seeeee
Intel fanboy sad because Ryzen 5 5600X gets nearly the same FPS in games as the i7 10700k and its way faster than the i5 10600k
Also your argument with 4400mhz ram is pointless because if you were to spend 1k$ on RAM you could simply just spend 10 times less for 3600mhz ram and go for the Ryzen 9 5950X which destroys any any 10th gen Intel CPU :)
Anyway, don't bother, see for yourself
And keep in mind that 10600k can work with 4400 mhz memory, not 3600, while 3600 is most comfortable frequency for ryzen 3000 (c) AMD.
Uhh yea I am sure they are pretty close yea. AMD says its trying to work on its BIOS to improve what ram the 5000 series supports, they are trying to bump it up to 3800 and possibly 4000 (but 4000 is not likely).
Currently you are fine, the 5600x is by far the best 6 core cpu, but with certain games it falls behind the 8+ core processors. If you look at any of the reviews of the newest ryzen cpus you will see it depends on the game a lot.
