Well, to test icc, you need to test both baseline performance, and performance after removing the Intel specific runtime checks that reduce it to worst-case scenario on AMD. I am not even sure anyone still maintains uncrippling tools for icc. I haven't tried using it since they stopped providing it for free. And back then it was an arms race, we kept finding ways to make it not suck on AMD chips and they kept breaking them.

sounds interesting with the -mtune=haswell. Is there some data that backs that up? Did phoronix run some benchmark comparisons on that? Might give that a try myself
Adding "-mprefer-avx128" raises LU benchmark score from 5000 to 6000.

Now, that's interesting. Got any sources?
It is a bigger problem on Windows where icc is used by many games and benchmarks.
