PS5 GPU je RDNA 2.0, tako da ne znam zašto spominješ 5700XT.
Uostalom, nije to tako jednostavno i binarno kao što ti to prikazuješ. Nije to 1/1.
Evo malo bolje objašnjenje ljudi koji znaju:
The SOC's that AMD are building for Microsoft and Sony are highly customized specifically for the vendors based on specs, cost, and performance requirements that each platform defines for AMD. There is no off-the-shelf equivalent of anything that goes inside an Xbox or PlayStation, and the idea they are "pre-made" really misunderstands what's happening and sort of diminishes the role of Cerny or the architects at Microsoft in terms of how much custom work goes into the chip.
AMD has IP and Processes. Sony and Microsoft work with AMD's list of available IP and Processes, add in some of their own requirements, and have an entirely new SOC created specifically for them. This process takes years. Everyone is aware that the PS4 Pro GPU had unique HW instructions for temporal reconstruction, as well as support for FP16 that did not exist together in other part of the AMD portfolio. The ability to decode Xbox 360 textures and much of the native DX12 instructions in the Xbox SOC's only appear in the versions that ship on Xbox (the DX stuff I believe ended up in later AMD GPU's.) This is the 'secret sauce' that is so often talked about, and it absolutely can work for (or against) a specific console. I don't think Sony got much mileage out of FP16, and Xbox One's implementation of ESRAM didn't help them as much as expected either. While the Checkerboard techniques helped PS4 Pro a lot, and the ability to decode X360 textures is why you have such a good back compat story on Xbox.
Here's the best way I can think of to describe it. Think of AMD as a Caterer. They have a list of ingredients (e.g. Zen, RDNA, HW RT, etc. etc.) and they also have a set menu based on their ingredients. (RX5000 series, RX Vega series, RX 500 series). Most people think that Xbox and Sony choose from the Menu. But what actually happens is they choose from the ingredients, add in some of their own specific ingredients (DX instructions, Back Compat Code, Checkerboard, etc.) and have an entirely new dish created just for them.
My point is that even though AMD's R&D efforts provide the groundwork, the specific SOC found in PlayStation and Xbox consoles are completely bespoke designs in collaboration with AMD and the platform makers, and are designed years in advance. This is why anyone speculating that wholesale performance changes can happen at any time don't seem to realize how far in advance these decisions are made.
Yes small changes can happen throughout the process and plans evolve from the initial spec to the final production silicon. But you can't grow the performance of the chips this late in the game without restarting some pretty critical, long-pole parts of the process.
I'm only speaking from one side of this, but I'm pretty sure it's similar on the PlayStation side.
