Details on the new radeon navi display and multimedia engine

The new series of Navi graphics cards have been announced with RX 5700 XT and RX 5700, which not only bring new performance advantages, but also a renewed display and multimedia engine, which are the Multimedia Engine and the Radeon Display Engine.

Radeon Display Engine and Multimedia Engine enhanced with Navi

AMD completed its first major update in more than two years in these two segments. The display engine is a hardware component that manages the I / O from the physical display to the graphics card. On the other hand, Radeon's multimedia engine is a set of fixed-function hardware that provides specific acceleration of video CODECs.

The display engine now includes an updated implementation of DisplayPort 1.4 HDR that is capable of handling 8K 60Hz displays with a single cable. It can also handle 4K UHD at 240Hz with a single cable. These also include HDR and 10-bit color. This is accomplished by implementing DSC 1.2a (Display Stream Compression).

The display controller also supports 30 bpp of internal color depth. The HDMI implementation is still HDMI 2.0. Low-power mode support was also added to the multi-plane overlay protocol (MPO). This should, in theory, reduce the power consumption of the GPU.

Radeon's multimedia engine is updated with support for more CODECs. For example, there is now support for decoding VP9 video in formats up to 4K @ 90fps (frames per second), or 8K @ 24fps. H.265 HEVC also receives 4K hardware accelerated encoding at 60 frame rates.

The new Navi RX 5700 graphics cards will be released on July 7.
