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.
