Reading the review from PCGH, I found out why the X3D beats the Zen 4 in several games: It's the GPU limit. Zen 4 bounces off of it, while the large cache of the X3D allows it to dig a bit deeper into the limit.

In other words, Ampere and Navi 2x are too weak to unleash the power of Zen 4 even just in 720p

Crazy how we went from 5600X which was as power efficient as a quad core 3300X to 7600X which requires almost as much power as 16 core 32 thread 5950x. While I am sure raptor lake will be even more nuts in terms of power, efficiency is clearly no longer a priority for any of these companies on desktop. I am looking forward to the laptop comparisons however since that is where we will see the biggest gains in performance per watt.

Keep in mind that they have a different TDP setting. If you set the TDP of the 7600X to 65W it will lose a bit of performance but consume also just about as much as the 5600X while having much more performance.

That being said, AMD should really have released a Ryzen 5 who comes with a TDP of 65W out of the box. Just releasing an uprated 105W variant (and that goes for all the Zen 4 chips so far) makes them look very inefficient.

Club386 has made an article doing that, but they compare the 7950X and 12900K at stock and also limited to 125W and 65W: https://www.club386.com/amd-ryzen-9-7950x-vs-intel-core-i9-12900k-at-125w-and-65w/

Limited to 125W they don't lose a lot of performace, but at 65W that's another story. The 7600X, and maybe the 7700X, being 105W CPUs, should see lower losses.

By the way, unsurprisingly, there's almost no loss in performance in any games tested except one, Far Cry 6 at 4K.
