I am really looking forward to .NET Native becoming widespread.
Then this type of comparisons (C# vs C++) will be quite
different.
I don't think it will make a major difference. Taking a GC
based language and giving it a native compiler doesn't
automatically make it performance competitive with C++(see
Haskel and D(without dumping GC) on anything besides micro
bench marks).
C# is still GC based, still makes heavy use of indirection(See
Herb Sutters recent talk on arrays).
Also possible in C# with structs, interop annotations and unsafe
blocks.
Don't forget that Herb Sutters also has a C++ agenda to sell.
C++ exposes SSE/AVX intrinsics, C# does not.
That is not correct.
1 - Nowhere in the ANSI/ISO C++ are SSE/AVX intrinsics defined,
those are compiler extensions. So equal foot with the C# EMCA
standard;
2 - .NET Native makes use of Visual C++'s backend with all the
automatic vectorization and other code generation optimizations
Visual C++ developers enjoy;
3 - .NET Native and RyuJIT have official support for SIMD
instructions, GPGPU support is also planned
