NVIDIA officially announced the RTX 40 series desktop graphics cards, according to the official press release, RTX 40 series finally support both AV1 hardware encoding and decoding.
The NVIDIA RTX 30 series already supports AV1 hard decoding but does not support AV1 hard coding, and this feature is finally completed on the RTX 40 series.
In 2018, the Open Media Alliance (AOMedia) released a new generation of video codec AV1 (AOMedia Video Codec 1.0). Developed in collaboration with the Open Media Alliance, the encoding encodes 4K UHD video with an average 30% higher compression rate than comparable encoders. Previously, only Intel Ruixuan supported AV1 codec, and neither Nvidia nor AMD fully supported it.
Nvidia said in a press release that the GeForce RTX 40 series uses the eighth-generation Nvidia Video Encoder, or NVENC for short, and now supports AV1. The new GeForce RTX 4090 brings a huge performance boost, 3rd Gen RT Cores, 4th Gen Tensor Cores, 8th Gen NVIDIA Dual AV1 encoder and 24GB of Micron G6X memory capable of 1TB/s bandwidth. GeForce RTX 4090 is 2x faster than GeForce RTX 3090 Ti in 3D rendering, AI and video export.
Nvidia RTX 4090 will be available on October 12, and RTX 4080 will be available in November.
