It is a bigger problem on Windows where icc is used by many games and benchmarks.

Oh, I thought you were referring to something more recent.

Well, it remains an issue. Except it doesn't matter so much on Linux anymore because you have to pay for the intel compiler, and no one appears to do so. I guessing they don't even bother giving Phoronix a free copy for free advertisement.

Of course it's an issue. This is the very reason why I haven't bought any Intel CPUs (besides a couple of second hand CPUs from eBay for computer that were given away to me).

Games on Windows are almost exclusively compiled with some form of MSVC. And yes, I've actually checked. I've NEVER seen a game that I own (and I own a LOT) compiled with ICC. GCC is rare as well; I think I've never seen a GCC compiled game outside of ID Software.

Funny enough, I once ran a tool called "Intel Compiler Patcher" in my Windows system to scan for "crippled" binaries (some 2 years ago, Windows 8.1) and it found that many DLLs from the AMD graphics and chipset drivers were compiled with the ICC and it's biased dispatcher.

To be the first version of this compiler is not so bad. Waiting for new versions in future

It's not much of a surprise, RyZen performs about as well as it's going to in Linux anyway and the lack of real number crunching hardware (only 1/2 speed support for AVX and no AVX-512 at all) can't just be magically optimized away in a compiler.

Not that any commercial software takes advantage of AVX-512 anyways. And those that do, are migrating to OpenCL or CUDA, moving those operations to the GPU instead.
