In a specific paragraph, where AMD said: “AMD demonstrated its “Polaris” 10 and 11 next-generation GPUs, with Polaris 11 targeting the notebook market and “Polaris” 10 aimed at the mainstream desktop and high-end gaming notebook segment. “Polaris” architecture-based GPUs are expected to deliver a 2x performance per watt improvement over current generation products and are designed for intensive workloads including 4K video playback and virtual reality (VR)”.
But there is one we need to focus on, ‘mainstream’. AMD has stamped the word ‘mainstream’ for everything between casual and enthusiast segments, where back in 2014, mainstream was associated with the Radeon R7 260.
So what does it mean? I think we’ll see Polaris 10 powering the Radeon R9 490X/490 and R9 480X/480, while cut down Polaris 10 will power the rest of the 400 series. In notebook market, the Polaris 11 should push 1080p 60FPS on latest games.
