For me, and the way I "think" when writing code, IntelC++ is faster, on Voxengo Soniformer plugin (very processing-intensive) compiled for x86 I get 8% more efficient code with IntelC++ than with gcc-c++ 7.3 (in MSYS2), in both cases SSE2 is enabled (can't check other instruction sets as SSE4 and AVX is not supported by 100% of user computers). That may not be considerable difference if you factor in compiler license cost.0degree wrote:@Aleksey - interesting, I always thought plugin devs compile on default compiler for the given platform - MSVC for win and Clang for osx. Is intel compiler really that faster?
I've also tested some other applications (high-quality image resizing, and gcc-c++ is even more behind - IntelC++ is 15% faster).
