AMD had claimed the Ryzen 7 9700X would outperform Intel's i7-14700K by 6% in gaming. They have revised this statement though, admitting that both CPUs should be...
Among AMD's bold claims about Zen 5's gaming performance was that the Ryzen 7 9700X would be 6% faster than Intel's Core i7-14700K. However, AMD has since walked back this claim, stating in a blog post that when running the 14700K with Intel's "Extreme" profile and the same high-speed memory that most reviewers use, the 9700X performs on par with the 14700K.
This was a bit of an odd comparison because, while the Ryzen 7 9700X and Core i7-14700K are priced as direct competitors, we wouldn't actually recommend buying either. The 14700K is priced at around $380, and the Ryzen 9700X is $340, but right now there are two other CPU alternatives that make far more sense.
If you're seeking the best gaming performance, it makes more sense to spend a little extra and get the 7800X3D. However, that's easier said than done, as availability is currently very poor.
So in the event that the 7800X3D isn't available, you can save money and opt for the 7700X, which you can grab for just $250 on Amazon, making it up to 26% cheaper than the 9700X. This is a much better deal for roughly the same level of gaming performance, regardless of the operating system, Windows 10 included.
Also let's not forget that the Intel extreme profile is probably not the recommended one, not that anyone would know what's recommended by them these days though.
