Would this have the same effect as disabling E cores?
Disabling E cores would likely only ever hurt performance or have no effect. That’s because this apparently works by automatically adjusting thread affinities to boost performance. Essentially Intel profiles a game, determine the optimal thread affinities for maximum performance, and releases a profile.
The reason this is needed is because in a game you have a lot of threads working in concert with each other to achieve the goal of rendering a frame to the screen and a generic thread optimizer doesn’t know that the thread it just put on the e-core is what the main thread is waiting for to pass instructions to the GPU.
For some games, this sort of thread affinity strategy will not boost performance.
AMD could probably do something like this for the 7950X3D and we’d likely see the discrepancy between it and the 7800X3D disappear.
