It depends. Straight compiles with no-optimization has shown them to be faster in some case and slower in others. If you have a specific application set that you can actually hand code a few things, the Intel compilers will take advantage of most of the features, gcc doesn't optimize. Some folks have gone with the Intel compilers for the entire system, but I've not heard of any reported results from their efforts. You can go over the SpecOrg and look at the results of the INT/FP results. All the Intel results are with the Intel compilers. Look at the test make up - which programs they used for testing, and see if it matches your workload. Then run the same thing on your currect system to see if it comes close or wildly different.
