On TimeSpy, the upcoming AMD Radeon RX Vega 64 scores about 7'600 points in the graphics score. The Sapphire RX Vega 64 Liquid Cooled will be going on sale starting the 14th of August and that is the same date when the embargo will be lifted. As you can see, both the Radeon RX Vega 56 and Radeon RX Vega 64 (seen directly below) feature a cooler design reminiscent of the preceding Radeon RX 480. This is an unusable Vega GPU die that AMD include in the package as a cool inclusion, something you could easily turn into a key ring or something like that. As you can see, the press kit was quite an elaborate affair, similar to what AMD sent us for the Ryzen Threadripper launch, and there were still plenty of goodies inside including a plexiglass cube with a "floating" 3D Vega logo inside.
In the above image we can see the dead Vega GPU, a cool little souvenir AMD is including within their Vega packaging.
As of today, AMD noted that RX Vega 56 cards have been shipped to reviewers, along with a request that reviewers specifically "prioritize coverage" of RX Vega 56 over RX Vega 64 under time-constrained conditions.However, according to what we know so far, the RX Vega 64 should sport a GPU frequency of 1630MHz and a memory clock of 945MHz.
