Sorry, but you’re completely incorrect. These aren’t “cut down” chips - the performance is equivalent to a 3700x and a 6800 when factoring in lower overheads. The 2 cores and 4 threads are crucial - a 5600 might have a better single core speed but as more games are released solely for these new consoles, the missing cores will age poorly. Compare the FPS at the same settings.

The PS5 doesn’t lock the FPS better. It has more performance than your estimates. You are wrong.

Upgrade your PC if you’re unhappy with the performance, or else you’d also have to re buy all your games and pay for online.
