help
Select this option to enable the AMD Heterogeneous Core Hardware
Feedback Interface. If selected, hardware provides runtime thread
classification guidance to the operating system on the performance and
energy efficiency capabilities of each heterogeneous CPU core. These
capabilities may vary due to the inherent differences in the core types
and can also change as a result of variations in the operating
conditions of the system such as power and thermal limits.
