Intel® Performance Hybrid Architecture
The processor contains two types of cores, denoted as P-Cores and E-Cores (P core is a Performance core and E core is efficient core ).
The P-Cores and E-Cores share the same instruction set.
The available instruction sets, when hybrid computing is enabled, is limited compared to the instruction sets available to P-Cores.
P core and E core frequency's will be determined by the processor algorithmic, to maximize performance and power optimization.
The following instruction sets are available only when the P-Core are enabled:
