gamesfreak64: Recommended system requirements:
Intel Core i5-3470, 3.20GHz or AMD FX-6300, 3.5Ghz
thats a lot , since an i9700K is only 3.6 ghz :D
Your post seemed to indicate you were doing a lot of analysis based on CPU GHz, so you should know that that is basically a pointless exercise that will only be misleading in the end.
GHz is just a very *very* *VERY* rough rule of thumb when estimating performance. It has *NEVER* been very meaningful for anything except comparing two different models of the same CPU, like one i3 versus another i3. ("NEVER" is literal here -- never, ever since the world's first CPUs).
(In addition to that, for some software/games it matters more whether you have 1, 2, 4, or more CPU cores, and/or whether your RAM is low versus high performance, and obviously sometimes the GPU is almost entirely what matters)
GHz has gotten even less meaningful in the last 10-15 years, ever since Moore's law stopped providing regular doubling of clock speed every few years (plus the fact that RAM performance has failed to at *all* to keep up with CPU performance).
GHz is only somewhat informative when it's obvious there is a huge difference *and* the CPU model is taken into account at least a little. A low power low performance 1 GHz Celeron is not going to be sufficient if the minimum requirement is a 3.6 GHz i9, regardless of fine details, because the two are separated by many years, and one is inherently a low performance family while the other is inherently a high performance family.
But is a 4.0 GHz i5 faster than a 3.6 GHz i7? There is literally no way to tell; that's not enough information. But they're both in the same *rough* category compared with any 20 year old CPU.
Ultimately this is a very deep, very complicated, ultra-technical subject that even engineers argue endlessly about, but the TL;DR is: never worry about small percentage differences in CPU GHz
Also note that these game store system recommendations are only very vague hand-wavy notions in the first place; game developers aren't experts on CPUs, they just say "well we tested it on lower-end CPU XZY and it worked, so put that in the requirements". It's never even close to exact, they just want to keep complaints and support costs to a minimum.
