AMD Radeon R9 Nano
The AMD Radeon R9 Nano is a compact high-end desktop graphics card aimed at small form factor PCs (e.g. Nano-ITX). It is based on the same Fiji chip as the Radeon R9 Fury and Fury X and features 4096 shaders like the Fury X. The clock rate is slightly slower than the Fury X (1.000 versus 1.050 MHz) but in games the real world clock speed is slower due to the aggressive power limit). The chips is manufactured in 28 nm at TSMC and features the third generation of the GCN architecture (also known as GCN 1.2). Another similarity is the 4 GB of HBM graphics memory that is also clocked at 500 MHz (4,096 bit = 512 GB/s).
The gaming performance of the R9 Fury is slightly above a GeForce GTX 980 (desktop and notebook) at maximum details and in high resolution settings (and clearly in 4K). The Radeon R9 Fury with less shaders but higher clock speeds (in games) however can pull slightly ahead on average (not in all games). All in all, the performance is sufficient for Full HD gaming with maximum details and anti-aliasing and in most games of 2015 also for 4K and high details.
The Fiji chip fully supports DirectX 12 (feature level 12_0) in hardware and also integrates a new Unified Video Decoder (UVD). Like the Carrizo APUs, the R9 Fury is able to decode H.265 UHD videos on the chip. However, the HDMI outputs still only support HDMI 1.4 and therefore 4K at 30 Hz. HDMI 2.0 and HDCP 2.2, like the GeForce GTX 960, are not supported.
The power consumption is a strong point of the Fury Nano thanks to the aggressive power target. It is rated at 175 Watt (compared to the 275 Watt of the similar fast Fury) and on average comparable with a GTX 980. Only the newer GTX 1060 and 1070 of the Pascal generation in 16nm can pull clearly ahead in terms of efficiency.
