Vega 10 was previously known as Greenland and is expected to be released sometime in 2017. The LinkedIn profile of Yu Zheng, a research and development manager at AMD, offers some clues abut the features of Vega 10.
The profile reveals that Greenland is the leading project of Graphic IP v9.0. In other words, this is the new flagship GPU that will succeed the most powerful Fiji processor currently offered by AMD. The graphic IP level 9.0 most likely stands for Vega architecture (the first to feature HBM2 memory). The project is tied with AMD’s SoC (System on a Chip) v15 architecture, which could suggest that future AMD APUs could also be somewhat connected to Polaris and Vega GPUs.It appears this GPU will feature 4096 shader processors and as was previously revealed, it will be made on a 14nm FinFET process. We don't know a lot of other details about Vega 10 but it's believed this GPU will offer 8GB of HBM2.
