Still proves my point all RDNA GPUs are based on the PS5's GPU as it was started first.That list only reflects when the project started, not when it finished.
What I said was the Navi started from the collaboration with Sony for the next gen console GPU, that's why the PS5 appears first in the list despite the design probably being finished after RDNA1 was ready to market and AMD was working on the other features to make RDNA2.
You think Sony/Microsoft didn't know about Infinity Cache? Both of them choose not to implement it in their console, seeing both of them have RT implemented.
You should also know, tech companies have tech ready but purposely hold back and release them in stages, so to give the consumers a reason to upgrade and make a revenue in the process.
So who's to say AMD didn't do the same with RDNA 1&2.
