Ahead of today's launch event, AMD showed off several of its new products.
Pictured below we have the Radeon RX Vega "Limited Edition" and the Holocube. I'm not sure what the Holocube is supposed to do but it reminds me of the Vega Cube prototype that was shown back in December 2016. But based on the limited info, it appears the Holocube it something else entirely.
Next there's a photo showing off both the Limited Edition and the liquid-cooled version of Vega.
What is a bit weird here is that these cards feature a Vega logo on the front of the card, whereas the model shown at yesterday's LTX 2017 event used a Radeon logo.
