Nvidia Encode Decode Matrix

On the encoding side there are no major changes.

Nvidia encode decode matrix. Intel amd and nvidia. This means that your gpu can operate normally regardless of whether you use this region to stream or record. It s a physical section of our gpus that is dedicated to encoding only. Nvenc is nvidia s encoder.

A history of formats. The video cards do not support av1 encoding though only the hevc h265 video format is supported. Not every solution exposes the same degree of processing. With decoding encoding offloaded the graphics engine and the cpu are free for other operations.

Gpu hardware accelerator engines for video decoding referred to as nvdec and video encoding. Nvidia updated the video encoding and decoding matrixes for ampere non a100 graphics cards geforce rtx 30. Other encoders such as x264 use your cpu to encode which takes resources away from other programs such as your game. Nvidia gpus contain one or more hardware based decoder and encoder s separate from the cuda cores which provides fully accelerated hardware based video decoding and encoding for several popular codecs.

The matrix has a reference dating back to the maxwell generation of nvidia graphics cards showing what video codecs are supported by each generation. Real time encoding of h 264 up to 4k 8 bit and h 265 up to 8k 10 bit are similar to pascal. Vp9 or other video codecs are not supported. The video encode decode matrix represents a table of supported video encoding and decoding standards on different nvidia gpus.

Decode and encode support. As for decoding so far hardware acceleration on gpu just lessens the burden on cpu side virtually anything can decode file in real time except load is bigger if there isn t hardware support but then again both amd and nvidia have support for decoding we just don t know how much the only results i found were for 3080 and i can t remember which cpu utilization dropped from 90 to.
