Dubbed the Radeon R9 Nano, the card is compact – 6-inches of Fiji GPU core built on a 28nm manufacturing process paired with 4GB of High Bandwidth Memory (HBM).
The card is 1.5 inches shorter than the Fury X, and unlike its liquid cooled sibling, there’s no radiator and fan assembly to mount.
AMD wants the world to see its R9 as the fastest mini ITX graphics card and space in those sorts of builds is thin on the ground.
The Nano has 64 compute units with 64 stream processors each for a total of 4,096 stream processors, just like Fury X. There are 256 texture units and 64 raster operations pipelines (ROPs), and with an engine clock of up to 1,000MHz.
All this means that the Radeon R9 Nano can do 8.19 TFLOPs of compute performance, which is pretty floppy. That is close to the Fury X, which features a 1,050MHz engine clock and do 8.6 TFLOPs when the wind is behind it.
The Nano uses 175W which is 100W lower than Fury X at 275W. According to AMD, the Nano offers up to twice the performance per watt as its previous generation Radeon R9 290X.
A single fan blows air over a large heatsink with densely packed aluminium fins. There’s also a dual vapour chamber block and heat pipes that run throughout, along with a dedicated heat pipe and heatsink for the voltage regulator.
AMD tells us the card is being “library quiet” with a claimed noise output of just 16 dBA.
AMD is claiming its Radeon R9 Nano isbetter than Nvidia’s GeForce GTX 970 in mini ITX form at 4K resolution in several popular titles. It even manages to hit 60 FPS in Grand Theft Auto V.
The Radeon R9 Nano will be available the week of September 7, 2015, for $649 MSRP.
