Intel® Hybrid Technology
The processor contains two types of cores, denoted as P-Cores and E-Cores.
The P-Cores and E-Cores share the same instruction set and model specific registers (MSRs).
The available instruction sets, when hybrid computing is enabled, is limited compared to the instruction sets available to P-Cores.
