Help text

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.
