The site did not hear about an exact release data from it sources, but suggests AMD could target a launch near the Supercomputer 2016 (SC16) show, which is hosted November 14-17, 2016 in Salt Lake City.
A launch in 2016 doesn't mean there will be a lot of cards available, FUD Zilla says there will be little volume. It's mainly to get customers excited, Vega 10 isn't expected to ship en masse until sometime in early 2017.
There will be Vega 10 cards with up to 16GB HBM2 memory, as well as versions with less memory. Vega 10 will be AMD's new high-end architecture and will compete against NVIDIA's Pascal.
