AMD shows off a render of the future Radeon Instinct card. This will be the first product to feature the 7nm Vega GPU, it's aimed at machine learning applications and will sample to customers later this year. Prototypes are currently running in AMD's labs.
Earlier this month, there were rumors that the 7nm Vega is exclusively for AI. At the moment, there's very little official information about what's next on AMD's GPU roadmap. We know the company is working on Navi, but that may be another mainstream GPU rather than a high-end product.
