AMD Polaris Architecture Coming Mid-2016
In early December, I was able to spend some time with members of the newly formed Radeon Technologies Group (RTG), which is a revitalized and compartmentalized section of AMD that is taking over all graphics work. During those meetings, I was able to learn quite a bit about the plans for RTG going forward, including changes for AMD FreeSync and implementation of HDR display technology, and their plans for the GPUOpen open-sourced game development platform. Perhaps most intriguing of all: we received some information about the next-generation GPU architecture, targeted for 2016.
Codenamed Polaris, this new architecture will be the 4th generation of GCN (Graphics Core Next), and it will be the first AMD GPU that is built on FinFET process technology. These two changes combined promise to offer the biggest improvement in performance per watt, generation to generation, in AMD’s history.
Though the amount of information provided about the Polaris architecture is light, RTG does promise some changes to the 4th iteration of its GCN design. Those include primitive discard acceleration, an improved hardware scheduler, better pre-fetch, increased shader efficiency, and stronger memory compression. We have already discussed in a previous story that the new GPUs will include HDMI 2.0a and DisplayPort 1.3 display interfaces, which offer some impressive new features and bandwidth. From a multimedia perspective, Polaris will be the first GPU to include support for h.265 4K decode and encode acceleration.
This slide shows us quite a few changes, most of which were never discussed specifically that we can report, coming to Polaris. Geometry processing and the memory controller stand out as potentially interesting to me – AMD’s Fiji design continues to lag behind NVIDIA’s Maxwell in terms of tessellation performance and we would love to see that shift. I am also very curious to see how the memory controller is configured on the entire Polaris lineup of GPUs – we saw the introduction of HBM (high bandwidth memory) with the Fury line of cards.

Ryan's coverage of the new Polaris architecture will be up momentarily but in the meantime you can take a peek at The Tech Report's coverage here. The new architecture will utilize FinFETs of an unspecified process node and is designed to power the new UHD displays and VR headsets due for release over this coming year. Raja Koduri discusses the two major goals of the new architecture, fast pixels and deep pixels. Fast pixels refers to the awe inspiring amount of bandwidth required to draw on UHD displays, twin 4K displays would require addressing 1.8 gigapixels per refresh which would certainly need some fast pixels. Deep pixels refers to improved support for variable refresh rates and likely encompasses support for the new HDR technology we will see appear on the market in the near future. If you can't hold off your curiosity for our coverage you can pop over here.
"AMD will release new Radeons built on its next-gen Polaris architecture in mid-2016. We got an early look at this new architecture and AMD's plans for building these chips with FinFETs last month at the company's Radeon Technologies Group tech summit."

A report claims that Polaris will succeed GCN (Graphics Core Next) as the next AMD Radeon GPU core, which will power the 400-series graphics cards.

As these rumors go, this is about as convoluted as it gets. VideoCardz has published the story, sourced from WCCFtech, who was reporting on a post with supposedly leaked slides at HardwareBattle. The primary slide in question has since been pulled, and appears below:

Of course the name does nothing to provide architectural information on this presumptive GCN replacement, and a new core for the 400-series GPUs was expected anyway after the 300-series was largely a rebranded 200-series (that's a lot of series). Let's hope actual details emerge soon, but for now we can speculate on mysterious tweets from certain interested parties:
