AMD’s graphics plans for Polaris are detailed – followed by Vega and Navi

It is now not far to AMD Polaris enters the scene. For the first time in over four years, it will be a new manufacturing technology and a really redesigned architecture, two aspects that together will make the next generation Radeon graphics card more than twice as energy efficient as the current one.

A new and more detailed product plan that has been found out contains further details about Polaris, but also the following graphics architectures. Once again, it is confirmed that the company has chosen a 14-nanometer technology for Polaris, which means that AMD is leaving TSMC and choosing Globalfoundries or Samsung as its manufacturing partner.

In terms of features, Polaris gets built-in hardware acceleration for encoding and decoding HEVC / H.265 video footage. The architecture will also be the first from AMD with support for both HDMI 2.0 and Displayport 1.3, where the latter, among other things, makes it possible to drive around 4K resolution in 120 Hz.

Most interesting is that Polaris looks to replace the entire AMD current range of graphics cards, where the large circuit Polaris 10 which is believed to have 2,560 stream processors replaces both the Radeon Fury series and the upper segment of the 300 series while the smaller Polaris 11 covers the lower. This goes against previous speculation that the Radeon R9 Fury and R9 Fury X would last at the top until 2017.

At the beginning of 2017, it’s time for Vega, which builds on Polaris and comes with the HBM2 memory technology, which with a doubled clock frequency compared to HBM provides a bandwidth of up to 1 TB / s. It will also be possible with higher capacities of 8, 16, and 32 GB, up from only 4 GB with the first generation HBM.

After Vega comes Navi and here is not as much known. According to AMD, the architecture must be scalable and equipped with a new generation of memory technology, where it is speculated that the memory circuits are stacked directly on top of the graphics circuit.
