According to WCCFTech, AMD's next-generation Vega architecture of graphics cards will see its launch on consumer graphics solutions by May 2017. The website claims AMD will have Vega GPUs available in several SKUs, based on at least two different chips: Vega 10, the high-end part with apparently stupendous performance, and a lower-performance part, Vega 11, which is expected to succeed Polaris 10 in AMD's product-stack, offering slightly higher performance at vastly better performance/Watt. WCCFTech also point out that AMD may also show a dual-chip Vega 10×2 based card at the event, though they say it may only be available at a later date.

AMD plans to roll out the "Navi" architecture some time in 2019, which means the company will use Vega as their graphics architecture for two years.
