When compiling the UE5 engine source code, it is found that the CPU usage is not high
Since the CPU is i5-12600k, this CPU has 6 performance cores and 4 energy efficiency cores
It can be found that during the compilation process, the four energy efficiency cores of the CPU are fully consumed, but the performance cores are basically useless
Under Windows 10, the compiler does not support CPUs with 12-generation hybrid structures in place, and it is enough to upgrade to Windows 11.
After upgrading windows11:
It can be seen that the CPU is full
If you do not upgrade to 11th generation windows, you can turn off all performance cores in the bios
Regarding the hybrid architecture, Golden Cove performance core + Gracemont energy efficiency core, in which the performance core supports hyperthreading, and the energy efficiency core supports single thread, in which the energy efficiency core supports lower power
But the new 13th-generation CPU has pulled the frequency of the performance core to the same size as the performance core. Thinking about the reason, it may be due to the pressure from AMD.
