This is confirmed in the Linux patch
Next-gen AMD Radeon graphics cards based on GPUs with RDNA2 architecture will support AV1 hardware decoding. This information was discovered in a Linux kernel patch provided by AMD.
The new Radeon will not lag behind the GeForce RTX 3000. AMD cards also have a hardware AV1 decoder
In this case, this is quite expected, since the main new products for the hardware market – Nvidia Ampere video cards and Intel Tiger Lake processors – also support AV1. At the same time, Windows and Google also integrate support for this codec into their products. AV1 is the successor of VP9, bypassing the latter in compression efficiency by 30-40% or more, so its support in new products, especially those designed for a long life cycle, is very important.
