The card is based on the same chip as the Fury X, with the full 4096 stream cores and a core clockspeed of up to 1000MHz! One sidenote though is that the clockspeed is not the base clock, it's believed to the theoretical maximum boost speed the R9 Nano can achieve under strict power requirements. The R9 Nano has a very short PCB, making it ideal for SFF and HTPC systems, and has a TDP of 175W, 100W less than the Fury X.
The Radeon R9 Nano will be equipped with 4GB HBM clocked at 1000MHz effective and has one HDMI plus three DisplayPort outputs.
There are still two big question marks ahead of tomorrow's launch. The first one is the price and the second one the performance level. If AMD's benchmarks can be trusted, the R9 Nano promises to be world's fastest Mini-ITX graphics cards. The firm's internal benchmarks show the card outperforms Mini ITX versions of the GeForce GTX 970 by 30 percent. If the company can launch the R9 Nano at GTX 970 level pricing it would make one hell of an impression, but that seems rather impossible if AMD wants to make money on these cards.
