The latest RDNA 3 architecture, on which the Radeon RX 7000 video cards will be based, may be inferior to existing Intel solutions in one of the areas.
Since the release of new cards is just around the corner, more and more details appear on the Web. So, in the code of the AMD Video Codec Next 4.0 (VCN 4.0) patch for Linux, mention was made of the possibilities of encoding AVC, HEVC and decoding AVC, HEVC, JPEG, VP9 and AV1. At the same time, there is no mention of support for hardware accelerated encoding of the AV1 codec anywhere. They are not found in any other sources. Given that the cards have not yet been released, it is too early to draw final conclusions, however, it is quite possible that the new Radeon adapters will indeed not have support for AV1 encoding.
At the same time, the Intel Xe-HPG architecture underlying Arc video cards has such support. Actually, so far only she has it, since Nvidia also does not have such solutions, and it is not clear whether the Ada Lovelace architecture will have appropriate support.
