C++ performance vs. Java/C#
... your c++ compiler will offer for different architectures is usually x86, x64, ARM and whatnot. Now you can tell it to use specific features (say SSE2) and if you're lucky it'll even generate some backup code if that feature isn't available, but that's about as fine-grained as one can get. Certainly...
