So you are just a troll.
You asked a link/source where the answer come directly from Cerny/Sony but you don't want to watch
And yes Cerny said even how it works... the processing (intersection) units inside the RDNA 2 that it uses and how it is the same as incoming AMD GPUs in PC lol
And yes Digital Foundry talked about what Cerny said on the video.
BTW dynamic clocks is a smart ideia to get more from the system

MS could use the same to get more from new Xbox if they wish (they will probably use int he mid-gen refresh).
