Yesterday, @ Kepler_ L2 shared some details of AMD vcn4 patch on twitter, but it seems that there is no sign that rDNA 3 "gfx11" GPU will support AV1 coding However, through in-depth exploration, we can now confirm that rDNA 3 actually supports AV1 coding It is reported that compared with the previous AVC coding, AV1 can bring 35% efficiency and power consumption improvement.
@Kepler_ L2 overturned the previous statement in a supplementary tweet. Although the previous code did not disclose any reference to AV1, amd did provide more than 12000 lines of code for the support of the new generation rDNA 3 vcn4.
It can be seen that with the arrival of gfx11, Navi 3x series GPU ushered in the fourth generation VCN coding, and its name was changed from "video core next" to "video codec next".
Obviously, the transformation from "core" to "codec" has clearly guided the company's latest plan. In addition, the soc21 (Navi 31) GPU code refers to the decoding capabilities of AVC, hevc, AVC, hevc, JPEG, VP9 and AV1.
Interested friends can pay attention to the subsequent code changes. If all goes well, we are expected to welcome a new amd rDNA 3 graphics card in the fourth quarter of 2022. At that time, the radeon RX 7000 series of the red team will have a head-on confrontation with the geforce RTX 40 series of NVIDIA.
