The ps4 used a gpu based on amd's "Southern Islands" gpu arch with some enhancements such as 8 asynchronous compute engines (ACE) which is a feature that hadn't become a staple on amd gpus until 6 months later when the "Volcanic Islands" arch debuted with the r9 290x, after amd had been using only 2 ACE units in its gpus for a long time. The ps4 pro currently has a gpu based on the "Polaris" arch with some enhancements from the "Vega" architecture including but not limited to FP16 Rapid Packed Math. Cerny already said that the ps5 will have a gpu based on the RDNA architecture and since he revealed that it'll also feature dedicated ray tracing hardware it'll also feature enhancements from RDNA 2, not the whole architecture. And I'm pretty much certain that Scarlett will take a similar approach (RDNA with RDNA 2 specific enhancements such as dedicated ray tracing hardware).it's going to be whole rdna 2.0 and on top of that secret souce there's no sense in releasing new console in late 2020 with 1 and half year old arch, same thing happend with ps4 it had never gcn which was only available on ps4 then soon followed amd pc cards.
add to this 7nm euv and we have 10+ tflops consoles with 200w -220w dsp.
