We might be on to something. With work pinned on one core:
cor CPU GHz TSC
1.16 1.00
0 0 1.17 1.00
1 1 0.80 1.00
When both cores are occupied:
cor CPU GHz TSC
1.00 1.00
0 0 1.00 1.00
1 1 1.00 1.00
In this case both cores are limited to 1GHz, but it might be intentional
to avoid overheating.
So there is some turbo functionality indeed. The frequency shown by
turbostat is still a bit off the target, not sure if there is any actual
problem though.
