Question Difference in cpu

[Icecole25]

Hey everyone I was wondering if someone would notice a big difference going from a i7 9700k to a i9 9900k?

Depends on the specific application.

In gaming, for example, probably not in most cases. For the most part, games are not really utilizing >8 cores, and clock speeds work out pretty much the same between the CPUs.
