Epic Games is undoubtedly among the developers with the best understanding of the PS5 architecture. Accordingly, there's a lot of praise for it at the moment, such as from Epic Games' Tim Sweeney, who recently elaborated on the storage system.
In it, he reiterates that one shouldn't rely on theoretical specifications, such as the 12 teraflops of the XSX versus the 10 teraflops of the PS5. These would only be achieved under absolutely optimal conditions. The same applies to the PS5's memory, which is designed and optimized in such a way that it currently outperforms any PC, regardless of individual components.
For this writes Sweeney:
"I'm referring to actual speed, not theoretical specifications. The PS5 can transfer and decompress textures and geometries directly from memory to video memory without the high overhead of CPU decompression and driver abstraction."
This means that the PS5, as previously stated, is superior to any PC on the open market, which are rarely as optimized as the PS5.
Sony has yet to provide proof of this, which will probably only be revealed at the earliest on the PS5 Reveal Event will receive what was just postponed.
