I thought it had higher clocks than ps5 too so I'm assuming not by your reply . To be honest I bore myself to death with tech specs and benchmarks, I just like to focus on the game most the time but it's still nice to know how they perform I guess.
Series X is 52 CU at ~1800Mhz whilst the PS5 is 36CU at ~2200Mhz.
Both are RDNA2 based “custom” jobs.
In some cases the extra clock speed will matter more thus closing the gap on the theoretical advantage the series X has. For example if there is a bottleneck somewhere in the rendering pipeline causing the extra CU’s to it be used in the most optimal way.
The Hitman grass section is quite interesting as the framerate drop occurs on both of the Series machines but not on the PS5. It may possible be a bug or could be a genuine limitation whereby running an adaptive resolution at this point would have made sense.
