How much should I worry about the Intel C++ compiler emitting suboptimal code for AMD?

Question

We\'ve always been an Intel shop. All the developers use Intel machines, recommended platform for end users is Intel, and if end users want to run on AMD it\'s their lookou

Answer 1

It's pointless to worry if you can't act. Possible actions are: Not buying AMD, or using a different compiler. So the obvious things to do are:

(1) Buy one AMD box, and measure the speed of the code compiled with the Intel compiler. Is it fast enough? If yes, you're done, you can buy AMD, don't worry.

(2) If no: Compile the code with a different compiler and run it on the AMD box. Is it fast enough? If no, you're done, you can't buy AMD, don't worry.

(3) If yes: Run the same code on an Intel box. Is it fast enough? If yes, you're done, you can buy AMD but have to switch compilers, don't worry.

(4) If no: Possibilities are: Don't buy AMD, throw all Intel computers out, or compile with two different compilers. Pick one.
