It's also a very bad sign that it's doesn't gets double the performance of a non hyperthreaded Intel 4 core parts while Intel 8 core parts do.
Considering it still loses to a 6900K (yes it's a very expensive part but it doesn't matter) in professional benchmarks and you lose native support for USB 3.1, vastly superior PCIE and storage performance, more PCIE lanes, and Thunderbolt it also doesn't bode well for AMD as the professional market is still going to go with Intel CPU's almost regardless of the price point.
And all it seems that Intel needs to do to beat AMD at their own game is simply to release 6 and 8 core non-HT parts at a 400-500 and 600-700$ price points since it would match the performance of a 6900K in virtually every professional application if Zen does become at any point a threat to Intel's sale.
