Let’s get to the main attraction: AMD's Radeon R9 Nano. The company made a lot of promises when it announced this card. It’s supposed to be smaller than most air-cooled graphics cards, but only slightly smaller than the water-cooled Radeon R9 Fury X. In addition, the Nano is claimed to be a more efficient implementation.
Before we get to our benchmarks, let’s go over the new card's specifications:

Small, compact and air cooled. AMD’s Radeon R9 Nano has enough confidence to forgo a backplate. Its shroud is almost entirely free of plastic and reminiscent of the Fury X’s. This is just for looks, though. There’s no actual rubberized removable cover. You'd only think so from a distance.
The exploded view shows the card’s components, from the PCA to the aforementioned cover.
As with AMD's Fury X, this card is especially compact due to the HBM (High Bandwidth Memory) stacked on the interposer. What’s new is the stabilization plate that makes contact with the voltage converters and carries their cooler. The VRM’s waste heat is transferred to this cooler via its own heat pipe. The sink doesn’t actually connect to the GPU cooler, but should still be able to take advantage of the fan’s airflow.
The graphics card’s design shows us that the GPU’s power supply is composed of just four phases. The included coils are also just standard fare, rather than low-vibration models.
The GPU cooler has a hybrid design. Instead of using a heat sink and pipes, there’s a large vapor chamber in the center and two massive heat pipes that extend to the ends of the thermal solution. This is an interesting new design, and we’re eager to test how well it works.
The cooling fins are aligned horizontally. This assures that at least some of the heated air is blown out the back via the slot cover.
The top and bottom of the graphics card are closed. This means hot air that doesn’t exit through the slot cover is blown out the opposite side and into your case. An eight-pin PCIe power connector sits right next to the opening. We can already tell you that one auxiliary connector is more than enough for AMD's Radeon R9 Nano.
As compact as the Nano may be, you need to add at least 3cm to its length as a result of that power connector pointing out the back. If all else fails, an angled adapter (available from any modding store) could save the day. It would have been great if AMD included connectors at the top and front of the card, giving builders a choice of which one to use.
There aren’t a lot of connectors on the back of AMD's Radeon R9 Nano. You get three DisplayPort outputs and one HDMI port. In light of the R9 Nano’s focus on high-resolution gaming, we’re really disappointed the company didn't update its display controller to include HDMI 2.0 support. Except for those Ultra HD TV set owners who want to fiddle with active adapters, 30Hz is all you'll get.
