Meet the Fury X's younger, bigger brother. AMD unveiled the Fiji-powered Radeon R9 Fury X graphics card just under a month ago. Outfitted with a new, space-saving memory technology called HBM and packing in more GCN cores than you could reasonably shake a big stick at, AMD played on the small-yet-powerful theme by watercooling the 7.5in-long card.

The $649 Fury X's graphical punch isn't hard enough to dislodge the rival GeForce GTX 980 Ti or GTX Titan X from the top of our performance charts, particularly at a 4K resolution where it matters most. But at least AMD is back in the high-end graphics game.

Yet stock has been in severe constraint for AMD's best-ever single-GPU graphics card while news of other Fiji-based models - Fury and Fury Nano - has tempted some enthusiasts to hold fire.
