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.
