AMD delayed Vega to ramp up volume
 

At least that is what company is saying

It appears that AMD has previously delayed the launch of its Vega GPU in order to have good volume at launch.

According to HardOCP's interview with AMD's Senior Director of Global Marketing and Public Relations at RTG, Chris Hook, AMD has intentionally delayed the Vega launch in order to make sure that they are launching with good volume. The recent popularity in cryptocurrency mining has affected AMD significantly and it was almost impossible to find some graphics cards, like the RX 580 or RX 570. Although there is still no precise details on Vega's cryptocurrency performance and hash rate, a significant volume will certainly be swallowed by miners.
