Introducing The Radeon R9 Nano
Today, we can finally answer your questions. Although specifications were released a few days back, they don’t tell the R9 Nano’s complete story. Strictly looking at the numbers makes this tiny graphics card appear to have some impressive specifications, mostly in-line with AMD’s current flagship, water-cooled wunderkind the Radeon R9 Fury X. As you’ll learn on the pages ahead, however, the Radeon R9 Nano is a different sort of animal—part beauty, part beast.
Let’s lay some foundation and cover the back-story before we dig in. Here are the AMD Radeon R9 Nano’s full specifications, in comparison to its two closest cousins, the air-cooled Radeon R9 Fury and the top-of-the-line Radeon R9 Fury X...
The Tiny, AMD Radeon R9 Nano
The initial release of the Radeon Software Crimson Edition has caused some issues with fan speed states on some Radeon graphics cards, but an update is due to hit the web today to address the problem.

Yes, the GPU powering the Nano is a fully functional Fiji like the Fury X’s with all of its functional blocks enabled, and its peak frequency is only 50MHz lower than the Fury X, but that more restrictive power envelope, coupled with the smaller, single-fan air cooler means the R9 Nano is less likely to run at full tilt, all of the time and remain within its target power envelope. In fact, here’s what the Nano’s frequency scaling looks like according to GPU-Z when running 3DMark Fire Strike.
We’re making this point early because understanding how the GPU clock scales on the Radeon R9 Nano with help explain the benchmark numbers you see a little later.
Before we get down and dirty, though, there’s lots of other information to cover. Since we’ve already detailed many aspects of the AMD Fiji GPU, we’re not going to run through it all again here. We would recommend checking out some of our recent coverage though:
