Amd polaris announced, new graphic architecture gcn 4.0
Finally, AMD has officially announced its new GCN 4.0 graphics architecture, which is called AMD Polaris and focuses on both a huge increase in energy efficiency and a large increase in the offered performance.
The graphics cards based on AMD Polaris will belong to the Radeon R400 series and will arrive in mid-2016, they will be manufactured in a process of 14nm FinFET from Samsung and will offer a great increase in efficiency and performance compared to the current GPUS manufactured in 28nm. Accompanying the GPU we will find the advanced HBM2 stacked memory that promises to offer bandwidths greater than 1TB / s.
The AMD Polaris GPUs will be equipped with HDMI 2.0 and DisplayPort 1.3a being able to decode and encode video at 4K resolution under the H.265 codec at a framerate of 60 FPS. In addition, the new Polaris architecture will have new Command Processor units, Geometry Processor, Multimedia Cores, Display Engine and an updated Caché L2 Memory Controller.

Amd would be working on a new gpu architecture to succeed gcn
AMD would already be working on a new graphics architecture to succeed the already highly obsolete GCN that hit the market in 2011.
Navi would continue to use the gcn graphic architecture
AMD has begun to introduce the first hints of its Navi graphics into its open source Radeon controllers. I would still use GCN.
The navi rx 5000 series will be a hybrid architecture rdna and gcn
Navi will use a hybrid configuration between the RDNA and GCN architectures. Navi 20 will be the first to use full RDNA.
