No matter how many times you repeat it the gpu does throttle. When and how often I don’t know. Tell me if it is constant then why have not have it at a set speed like Xbox?
I don't want to get into it but no PC GPU for a long time has constant clocks and it is a waste of power and logic. And the same happens in the processors if you go into the configuration of your motherboard and see the advanced overclock part, you will find the AVX offset option that its function is to lower the clocks in front of AVX functions and I do not see anyone complaining about it in PC.
On the other hand, we can admit that PS5 has a variable frequency similar to what all PCs have, but we must also admit that 14/12 CU in an antisymmetric way per shader array that the SX has together with the divided memory that Xbox has is the largest botch that has never been done to the point where developers prefer to develop on switch versus SX.
Precisely for this reason, PS5 finally obtains much better performance than SX because the IO controller improves performance with greater use of CUs and also due to the improvements that not having as much memory as pool provides.
On the other hand, as for UE5 on PC, it is true that it can be moved in project mode but nothing assures me that the same precision of triangles is being used, nor that the rasterizers in project mode are taking simplifications, we do not know how it would move. currently the project on PS5 or how it would move on a PC with 8k textures. UE5 is very scalable but moving the project does not have the same fidelity as the game, it is heavier for the CPU and for multitasking, but graphically many simplifications are taken since its main priority is to move fast.
In the second demo and the first they have not demonstrated the flight speed which is where the IO controller stands out and it is precisely those mechanics and teleportation along with using less memory as a pool that really makes the change.
You are comparing a demo of 1 year ago of PS5 with something current without running in project mode and possibly with more simplifications than textures, for example the spin speed or an analysis of ms to see poppping, you are seeing how UE5 scales great since That's what it was designed for but we can't see how it currently moves on PS5 that its performance could be much higher, nor have we seen things actually moving on PC and most importantly we haven't seen any area where there is a fast scrolling speed.
There are still too many unknowns that we should clear up before starting to despise the PS5 hardware
