Intrinsics Vs inline ASM for SSE coding in VC++ 2K8

Question

I've done some inline ASM coding for SSE before and it was not too hard even for someone who doesn't know ASM. But I note MS also provide intrinsics wrapping many such special instructions.

Is there a particular performance difference, or any other strong reason why one should be used above the other?

To repeat from the title, this is specifically covering intrinsics exposed by VC++ 2008 for unmanaged, native C++.

Answer 1

There is no inline assembly in Visual C++ for x64. Intrinsics can be used on x64 as well. If you ever want to port your code to x64, you'll have to use intrinsics.
