One might expect that this launch could happen at this year’s Supercomputer show in November but we didn’t get a precise date. AMD could use Vega 10 for both the professional graphics market and the compute market.
At its highest end the Vega 10 GPU has 16GB HBM 2.0 memory, which is what you would see if you opened the bonnet of hte Nvidia P100 cards. There will be a version of the card with less memory too.
The fact that AMD / RTG plans to launch the card this year, doesn’t mean that they will have too many to sell. The general idea is to get the customers excited and ship in volume in early 2017.
This will put the RTG professional group in a better position as the Vega 10 is expected to compete better against Nvidia. We will see how much the new Vega architecture can benefit from the faster memory and memory interface. AMD could use this a sales push in this highly profitable market.
As Fudzilla already suggested, there will also be a Vega 20 GPU, a successor to Vega architecture which will arrive after the first one.
