The first official performance numbers of the AMD Radeon R9 Nano graphics card have been leaked by Videocardz. The benchmarks show the Radeon R9 Nano pitted against the GeForce GTX 970 Mini which it manages to outperform in all the gaming titles. The Radeon R9 Nano going to be the latest graphics card, featuring AMD's Fiji GPU core and HBM architecture in a compact Mini-ITX design.

AMD Radeon R9 Performance Shows Fastest Mini-ITX Graphics Card Ever

The AMD Radeon R9 Nano is based on the full fat Fiji GPU core. The design is by no means cut down and its amazing how the Fiji GPU runs so well on a design this compact. Based on the 28nm HPX process, the Radeon R9 Nano features 64 compute units which have 64 stream processors per CU, these round up to a total of 4096 stream processors which is the same core count featured on the flagship R9 Fury X graphics card. The card comes with 256 texture mapping units and 64 raster operation units. While the Radeon R9 Fury X has a compute performance of 8.6 TFlops with its 1050 MHz engine clock, the Radeon R9 Nano comes with a total compute performance of 8.19 TFlops with its 1000 MHz engine clock.

The 1000 MHz clock speed for the Radeon R9 Nano is quite impressive indeed as this package as a whole is 175 Watts that is 100W less than the Radeon R9 Fury X (275W). The Radeon R9 Nano is designed to feature greater performance efficiency numbers compared to both Radeon R9 290X and the Radeon R9 Fury X which it achieve with ease. Now here’s the scene, the Radeon R9 Nano has a total board power that is limited to 175W, pumped through a single 8-Pin connector. The GPU isn’t necessarily working at 1000 MHz all the time, the core clock can be optimized based on the needs of applications and games. The Radeon R9 Nano seems to be the fastest and most perfect Mini-ITX graphics card with a compact design and a thermal solution that should provide even better stability and temperatures than the Radeon R9 290X graphics card as mentioned in the slides.

As for performance numbers, the Radeon R9 Nano turned out to be faster in all the gaming titles compared to the GeForce GTX 970 Mini which is currently the fastest Mini-ITX offering in the market. This is kind of expected since the Fiji GPU has a lot of performance packed inside its hood and it rivals the GM200 in performance than the GM204 GPU core which the GeForce GTX 970 and GeForce GTX 980 is based on. This shows that the card is actually faster than the two GM204 products that NVIDIA has to offer but also AMD's own Radeon R9 390 and 390X graphics card. I believe that the card will be very close to the Radeon R9 Fury (Fiji Pro) in terms of overall performance but that is something we would have to confirm when actual reviews make their way on the net.

Some performance results were also published by AMD in their Hot Chips presentation shows that the Radeon R9 Nano will deliver 33 FPS compared to 30.5 FPS (Radeon R9 290X), while the Radeon R9 Fury X blisters past 40 FPS at an exact FPS rate of 42. The benchmarks were obtained at 4K resolution so its quite obvious that AMD Fiji based parts will have higher performance due to higher bandwidth (512 GB/s). The performance per watt with these results was insane with Hawaii taken at reference at 1.0% while the Fury X has 1.25x and the R9 Nano at 1.9x (up to 2.0x) times more energy efficient compared to Radeon R9 290X which is insane. Still, the performance is amazing from a card that measures just 6 inches and we hope to learn more about the Radeon R9 Nano in the upcoming days.
