During its Capsaicin event at Game Developer Conference 2016 in San Francisco, AMD has unveiled its new GPU architecture roadmap, providing more details about its future GPU plans, including details about the new Navi GPU architecture which comes after Vega and should be ready in 2018.
Unfortunately, the new "projected roadmap" does not reveal a lot of details and raises some interesting question. According the roadmap, AMD's Polaris GPU architecture will offer 2.5x performance per watt compared to AMD's current 28nm GPUs. AMD has confirmed that we will see Polaris 10 and Polaris 11 GPUs, with the Polaris 11 being the smaller GPU.
The next Vega architecture is scheduled to come in 2017 and feature 2nd generation High Bandwidth Memory.
The new architecture, codenamed Navi, does not come with a lot of details, other than we can expect it in 2018. It will offer scalability and "next-gen memory".
What makes the roadmap quite interesting is the fact that Polaris architecture will probably come with either High Bandwidth Memory (HBM) and GDDR5(X) as the 2nd-generation High Bandwidth Memory will be only coming with Vega GPU architecture.
Unfortunately, AMD did not reveal any new details regarding Polaris architecture during the Capsaicin event so hopefully we will hear more about it during GDC 2016.
