The Jaguar CPU in these consoles are actually two quadcore units. And because of this latency between the two modules is pretty high, so the second module is rarely used for anything more than OS and some side tasks. The Main game thread and all extra main game threads tend to only run on those 4 cores. It was a really poor choice for a Console CPU, I fully blame AMD for pushing that design choice. The PS4 would have held up so much better if it only had a better CPU. Really should have used a 3-4 module Bulldozer setup. Jaguar has such high latency between the two quad core modules it makes scaling a game engine on these devices past 4 core impractical. Bulldozer wouldn't have had this issue. Plus the mid cycle console refresh would have a good deal more powerful. So much so that we probably wouldn't have gotten the PS5/XSX this year, which would have been a great thing. As IMO this generation of consoles should have had a DLSS type of hardware solution.
Putting aside the fact Bulldozer wasn't great either, it never would have been used due to heat constraints and the necessity for also developing an off-die GPU unit, increasing both costs and power draw.
Lets also remember that prior to the Witcher 3 release, CDPR openly criticized the CPU horsepower on both consoles. So I'm not shocked in the least a far more graphically heavy game is running into significant issues.
