Phoronix did that with TSCP - hardly any improvement over GCC 6.3 and inferior to CLANG 5.tttony wrote:Now test with chess engines to see if there are improvements

It's interesting, however, that GCC 7 is slower than GCC 6.3, and GCC 8 even slower than GCC 7. Seems to be a regression.
On a general note, AOCC does not deliver anything remarkable. Seems AMD forgot an important point with a compiler optimising for Ryzen - that is, to actually deliver faster binaries.

Right, they obviously took Clang and LLVM and hacked in some "ryzen optimizations" that don't seem to help at all.Ras wrote:On a general note, AOCC does not deliver anything remarkable.
