I can't see how changing anything else apart from clock (and thus probably voltage) would make sense. Disabling simds but running at higher clock almost certainly will do worse in perf/w - turboclock switching to higher clock (and higher voltage) with some cores disabled only makes sense because there you still have single-threaded tasks (or let's call them low-threaded tasks).Yes, I've read that but I was wondering how it was being done. If there was more to it then clock rates.
What I'm wondering though is if it can finally lower memory voltage. That should have a quite good return in perf/w, since current AMD chips overvolt the memory. If it would lower memory clock just a bit it could likely lower memory voltage quite a bit more. But I guess the new dynamic switch stuff is only affecting the gpu, since changing memory clock / voltage takes too much time.
