RX Vega 64 is able to offer near GTX 1080 performance in most DirectX 11 titles, but performs exceptionally in newer, DirectX 12 games where it is able to exceed the performance levels of the Nvidia card. The Strix version coming from ASUS does feature a factory overclock, but the speed it will actually run at really depends on multiple factors such as power limits (for the GPU, HBM2 memory) but also temperature. When trying to overclock the card, we could not increase the clock much further, which is telling us that the Strix is pretty much running already at max capacity.
