This project provides tools to benchmark and analyze performance characteristics of Intel CPUs with hybrid architecture (P-cores and E-cores) on Windows systems.

• main.cpp: Demonstrates basic P-core and E-core task allocation
• bench.cpp: Performs comprehensive benchmarking of core switching and performance

main.exe

bench.exe              # Run mixed P-core and E-core benchmark
bench.exe --p-core-only # Run P-core only benchmark
bench.exe --e-core-only # Run E-core only benchmark

1. Open the solution file in Visual Studio 2019 or later
2. Select Release configuration
3. Build Solution (F7)

Build with MSVC compiler from Developer Command Prompt:

cl /O2 main.cpp
cl /O2 bench.cpp

For detailed analysis and benchmark results, check out: Benchmarking Context Switching Between P-cores and E-cores on Intel CPUs
