Radeon RX 6000/7000 with multi-track streaming support

AMD has now confirmed that Radeon GPUs support an improved broadcasting feature for Twitch.

Twitch has been collaborating with major GPU vendors to support a new multi-track transcode streaming technology. Commonly used in television and video conferencing, this technology ensures that viewers can access streams regardless of the bitrate. However, due to the high transcoding costs, especially for live streams, Twitch does not offer transcoding for all videos.

The company realized that instead of transcoding the video streams themselves, they could rely on the streamers’ hardware directly. NVIDIA announced that Twitch Enhanced Broadcasting would allow users to stream up to five concurrent videos of various transcoding qualities for Twitch viewers to choose from.

AMD has now confirmed that their Radeon RX 6000 and RX 7000 graphics also support this technology. AMD has not confirmed the exact number of concurrent streams or which codecs are supported, but some of these details can be found on the Twitch website.

Twitch clarifies that this technology currently works with Adrenalin 24.4.1 drivers or newer. Users should use Windows 10 or 11, and this technology is now supported by two software applications: OBS Studio 30.2+ and XSplit Broadcaster 4.5.2406.1801+.

Enhanced Broadcasting currently focuses on 1080p resolution and H.264/AVC codecs. The technology will expand to higher-quality streams with AV1 and HEVC codecs, which are currently available to a limited number of streamers. Furthermore, 1440p and 4K streams will also be added and are already being tested. However, HDR support and streams above 60 FPS are not currently being tested or planned.
