Yo what's wrong with you people? Have we all forgot that both Sony & Microsoft have called their consoles' GPUs as "Custom RDNA 2"?
Consoles have always been like that, just like how PS4 Pro was based on Polaris architecture & had some features from AMD's future GPU generation, the Vega architecture, so this is the same logic applied here, PS5/XSX have RDNA 2 GPUs, they might have some features from RDNA 3, they might lack a feature or two from RDNA 2 itself, it's why they call these consoles "Custom RDNA 2", that's all, both Sony & Microsoft want to put certain features that they feel they need for their consoles, but somehow Xbox fanboys found something to brag about because apparently, the PS5 is "between RDNA 1 & RDNA 2" which the same guy has just corrected his statement about it and said that he should've reworded it properly.
