This benchmark heavily stresses branch misprediction recovery, so that could be worse on Zen.
Also, I could not reproduce Daniel's results: I got IPC of 1.77 (SKX) or 2.00 (SKL) compared to Daniel's reported 2.80 (SKL, I think), so Intel still better but by a smaller margin. Waiting for clarification on that one.
