AMD uploaded a teaser video for what appears to be the Fiji XT graphics card. No further details were revealed but the YouTube link contains a link to Twitch so perhaps this is a hint that the launch event will be livestreamed.
Another picture of the Fiji XT hit the web yesterday evening, the photo doesn't show the whole card but reveals it uses watercooling and after turning up the brightness you can see it has two dual 8-pin PCIe power connectors. The card seems to have a pure metallic shroud, it has a very short PCB for a high-end card (thanks to HBM) and features some fancy illuminated logos. We also hear AMD is dropping DVI support with the Fiji XT, the card will exclusively support DisplayPort and HDMI.
