Sapphire has now officially confirmed that according to earlier pictures, the RX Vega 56 Pulse will be officially available as of February 12 and according to the specifications, it should be cheaper than the Nitro+ version:

Unlike the Nitro+ series, the new Sapphire RX Vega 56 will have a somewhat modest factory overclock of 1208MHz GPU base and 1512MHz GPU Boost clocks. Earlier pictures revealed it uses a custom PCB, drawing power from two 8-pin PCIe power connectors. It also comes with a dual-fan, dual-slot cooler.

An earlier leak by Alternate.de was apparently spot on as Sapphire has confirmed on its Facebook page that it will be available as of February 12th.

The earlier leaked listing puts the Sapphire RX Vega 56 Pulse at €789.
