It's PS5 RDNA 1.5 all over again, and reading responses, like a certain fandom never gets tired of being let down or uninformed. There's reasons PS5 often outperforms Xbox Series X despite the latter having 44% more compute than PS5 and being "full RDNA 2", which Digital Foundry did... a video on. As I said at the start of the gen, most RDNA2 features Xbox/PC fans claim PS5 is missing, it was unlikely to use as they're Microsoft DirectX RDNA tie in features, and PS5 doesn't use DX but instead its own proprietary custom API called AGC. Why would PlayStation push for Microsoft DirectX RDNA features, when they don't use DirectX? Any AGC API specific graphics features PS5 uses (that Xbox wouldn't have) are not widely publicly advertised, as PlayStation don't need to advertise them the way Microsoft does due to their PC DirectX market. Thus every customisation PS5 has (which Kepler seemingly glosses over or doesn't recognise), from its faster clockspeeds, cache scrubbers, I/O set up, CPU alleviating decompression, DMA controllers and processors, geometry engine etc, will have been specifically designed around AGC or vice versa, NOT DirectX RDNA2 features. PS6 will be no different. There may be DirectX RDNA5 features they do not need or use, but there will inevitably be other unique customisations of their own and for their OWN proprietary API instead, no doubt bolstered by Amethyst custom features from their partnership with AMD. If history is any indicator, PlayStation is right to prioritise their own API and modifications, as these tend to have greater cost to perfomance results for the hardware vs the competition. The RDNA2 DirectX image below is taken directly from AMD's website, and again, PlayStation doesn't use Microsoft's DirectX. #PS6show more
