AMD today unveiled the Radeon RX Vega 56 Nano, the spiritual successor to the disruptive high-end SFF graphics card, the Radeon R9 Nano. Unlike the R9 Nano, the RX Vega 56 Nano is an AIB (add-in board) partner effort, specifically by PowerColor. The card itself is a good inch longer than the R9 Nano. Also, unlike its predecessor, it doesn't feature all stream processors physically present on the silicon. The card is cooled by a dense aluminium fin-stack heatsink, ventilated by a single fan.
