That’s kind of my point. Linux supports it, but Windows doesn’t anymore. Why? Money - OEMs aren’t selling them anymore, so why spend time to support new features on them? On the flip side, the heterogeneous chiplet structure of the 7950X3D was supported on Windows from day 1, while on Linux the scheduler is still unaware of the different perf characteristics to this day. Why? Same answer - money. AMD doesn’t make money selling 7950X3D on Linux, so they’re not going to spend time writing a kernel driver to optimize perf on it.
