MinGW 4.7.2 vs. Visual C++ 11.0 (2012) Benchmark

Tags:

I have been doing an experiment to choose between MinGW and MSVC. I decided to use Adobe C++ Performance Benchmark to do it. While MSVC's output was exceptionally faster on some operations, it was as slow on some other operations. I will add other parts of the benchmark suite when I have time to do them.

I have removed some of the benchmarks that has same results due to character limit, you can interpret them by the pattern I assume.

System Information

  • AMD Athlon(tm) 64 X2 Dual Core Processor 5200+ 2.70GHz
  • 6GB DDR2 800MHz RAM
  • Windows 8

Any idea why the result is slow? Also, can this test's result to interpret a computer game performance (CPU physics engine maybe) because especially floating point benchmarks are slower?
