It avoids using some performance instructions which it uses on the Intel build and which would work identically on AMD.
Their excuse is that they can't guarantee they would work identically on AMD and so resort to much slower un-pipelined code. It's like Ferrari testing a Porsche and only using 1st gear because they can't be sure that other gears would perform in the same way
