This doesn't look like it was really meant to happen, but it is in the wild now! Twitter user Drew has posted a picture of Chris Hook holding up a Vega Nano card outside the show. It draws its design from the previous Vega products that we have seen with the shroud and the red cube in the top right corner. No specifications were included with this post, but we can see that the card is significantly shorter than the RX Vega FE that Ryan had reviewed.
TDPs should be in the sub-200 watt range for such a design. The original Nano was a 150 watt TDP part that performed quite well at the time. Pricing is again not included, but we will be able to guess once the rest of the Vega lineup is announced later.
