Side by side comparison.


9900K have advantage over 8700K in term of 400Mhz clock speed and 2 core 4 thread more. This can translate to a bit extra FPS (both AVG and 1% low , 0.1% low) if your GPU is strong enough and playing at 1080p or lower.
 
I think another reason for the performance decrease with the i7 is due to the core count.

Say a game uses 8 threads
The 9900k would be using only its 8 physical cores.
The 8700k would be using all 6 of its physical cores and 2 of its significantly weaker hyperthreaded threads.

I wouldn't be surprised if I am completely misunderstanding how Hyperthreading works tho.

and thats why you skip at least 4 gens, the next one nowadays represents a boost so small it can be overlooked, and it gents wonky to decide between 6/12 or 8/8, although 8 real cores seems to be better most of the time... most of the time.

Yea the 9700k @5ghz vs 8700x @5ghz has always been a confusing one.

Considering Hyperthreads (IDK if that's the correct word) are far weaker than actual cores and HT has a certain overhead, i still feel 8/8 is better than 6/12.

If you asked me a few months ago whether to go 9700k or 8700k, my answer would be different than today.
