AMD officially announced Polaris, its new graphics architecture that will involve major change in architecture since AMD launched its first 28nm GPU in 2011. This new architecture will give life to Radeon 400 series graphics cards and according to the company’s plans the first graphic card will be released in summer. All of them make up a new Command Processor, Geometry Processor, Multimedia Cores, Display Engine and updated memory controller with L2 Cache memory.
AMD Polaris architecture – GCN 4.0
To give you a perspective, this is how Polaris fits after 28nm architecture.
- 2011 — 28nm GCN 1.0 — Tahiti / Cape Verde
- 2013 — 28nm GCN 2.0 — Hawaii / Bonaire
- 2015 — 28nm GCN 3.0 — Fiji / Tonga
- 2016 — 14nm FinFET Polaris (GCN 4.0)
All unified brings a new macro-architecture optimized under FinFET manufacturing process will mark a historic step in performance per watt thrown into a GPU AMD Radeon. All Polaris based graphics will have HDMI 2.0 connectivity, 1.3a DisplayPort. They are able to decode / encode video 4K under the H.265 codec @ 60 FPS and, like NVIDIA Pascal, will feature a High Bandwidth Memory 2 (HBM2).
The new architecture will be twice as fast in comparison with Fiji and support second generation of High-Bandwidth Memory (HBM2), which is also manufactured by Samsung. While HBM1 memory has a physical limitation of up to 4 GB of capacity and a bandwidth of 512 GB / s, HBM2 memory allows the use of up to 16/32 GB of VRAM that can exceed 1024 GB / s.
AMD has promised to reveal more about Polaris over the coming months, as well as drop more details at this year’s CES, currently taking place in Las Vegas.
