Just need to remind you things that i said before for the last time\
GPU: PS5>SeX ~10%
RayTracing Accelerators: PS5>X1 (PS5's RT works by using acceleration structures and algorithms much like nVidia's RTX cores)
CPU: Sex>PS5 ~ 6%
Memory: PS5>Sex for the size and bandwidth
SSD: PS5>Sex ~ Over twice as fast (this is the biggest and most noticable difference)
Fan noise (Dev-Kit): Sex>PS5 (not as egregious 1x vs. Pro).

BTW it's up to you believe me or not, but things gonna be clear very soon and you will find out who knows and who knows ****.

Bonus?
Remedy and Housemarque have been in Sony's WWS family for a while now!

Techland belongs to MS now!
