Finally, along with today's announcement RTG is also disclosing a bit of what we can expect for Polaris's multimedia controllers. On the decode side RTG has confirmed that Polaris will include an even more capable video decoder than Fiji; along with existing format support for 8-bit HEVC Main profile content, Polaris's decoder will support 10-bit HEVC Main10 profile content. This goes hand-in-hand with the earlier visual technologies announcement, as 10-bit encoding will be necessary to prevent banding and other artifacts with the wider color spaces being used for HDR. Meanwhile RTG's UVD video encode block has also been updated, and HEVC encoding at up to 4K@60fps will now be supported, marking a major jump over the previous generation encoder block only supporting H.264. There is no word on whether that will include Main10 support as well, however.
