Games perform better on 6-core 7600X compared to a 10-core i5 13400 because they're tuned for fewer processors.

13400 is not a traditional 10 core. Its basically 6 core+ 4 slow cores that wont be utilized by most games. So what you should be asking are the 6 cores of the 13400 faster or slower then the 7600x 6 cores (Not really they should perform roughly the same). Games are not Optimized for lower cores persay, its moreso that its a usage and utilization thing. It varies Game dev to game dev, some use 2-4 cores, some use 4-6, some use as many as you can throw at them. There is no one method to the game devs. Most games benefit from more cache (hence why the 7800x3D is so strong), the speed of the cores, and the IPC (instructions per clock) with a few other factors.
It varies depending on the game being discussed. Generally, it tends to be GPU intensive. However, looking at CPU core counts across different systems is similar to comparing gigahertz values (ignoring P and E cores). It's usually wiser to check the benchmarks directly to determine what suits your requirements best.
The AMD and Intel chips have changed. When we look at cores from the same processors, AMD tends to deliver better results, leading to improved gaming performance.
You'll notice the 7600X performs roughly 10% better overall in games versus the 13400F with a 4090 at 1440p and 12% at 1080p. That's not a huge difference. https://www.techpowerup.com/review/amd-r...3d/20.html If you prefer Intel, consider looking into the i5 14500 instead.
Games are designed for a specific core count. They run efficiently with that number. Extra cores may be used by background tasks or remain unused, leaving no impact on performance.
