VideoCardz has a bit more information and photos. They conclude the Vega card looks a little bit faster than the GeForce GTX 1080. The site also learned this card has 8GB of video memory.
Where does it put us performance wise? Somewhere around GTX 1080 level, probably little higher. There are more pictures available, like the one below from PCGH, showing indoor footage at 66 FPS. Cards were tapped at the bracket to eliminate any risk of a leak. This could’ve affected the airflow of the card, and also reduce its performance.
One more thing, it appears that 687F:C1 device that was leaked just a few days ago through AOTS benchmark website is indeed VEGA, as confirmed by PCGamesHardware.
