The MSR prices for the standalone Vega 56 and 64 Black (as we
reviewed them) are 399 and 499 USD repectively, as AMD let the media know these prices. Both cards can be spotted and advertised (if you can find them at all) for 499 and 599 with the 56 being a preorder and the physically 64 available. However that 100 bucks extra, here's the thing these would be the bundled versions with Prey and the to be released Wolfenstein II: The New Colossus. So, if the cards are physical available then the question rised, was the stock for non-bundled Vega kept low deliberately ?
Currently, where I reside in the Benelux, cards are simply not even available. All in all we are rather confused about this launch, and the prices are a bit of a mess with all these confusing bundles and low availability of the standalone cards. Currently prices are way higher compared to the GeForce GTX 1070 and 1080.
Long story short, if you are in the market for a Vega 64, you'll be spending at least a 100 USD/EURO more opposed to the introductory prices.
