Nvidia Ampere Hevc

The encoding performance on ampere gpus scales up with the performance numbers on turing gpus in proportion to the highest video clocks as reported by nvidia smi.

Nvidia ampere hevc. It is named after french mathematician and physicist andré marie ampère. For decoding purposes the ampere lineup now includes support for av1 8 bit and 10 bit formats while also supporting all of the previous generation formats. Nvidia updated the video encoding and decoding matrixes for ampere non a100 graphics cards geforce rtx 30. Table 2 provides indicative data of the decoding performance of nvdec in gpus based on maxwell pascal turing and ampere architectures for av1 hevc vp9 and h 264 encoded bitstreams.

The performance varies across gpu classes e g. Nvidia nvenc is a feature in nvidia graphics cards that performs video encoding offloading this compute intensive task from the cpu to the gpu it was introduced with the kepler based geforce 600 series in march 2012. Here s everything we know about the fundamental changes. Quadro tesla and scales almost linearly with the clock speeds for each hardware.

Utilizing nvidia gpu hardware acceleration. For example the table shows that while supporting all of the previous generations of encoding standards the ampere based gpus feature support for hevc b frame standard. Nvidia s ampere architecture powers the rtx 30 series graphics cards bringing a massive boost in performance and capabilities. Gpu hardware accelerator engines for video decoding referred to as nvdec and video encoding.

Hevc 8 bit and hevc 10 bit. 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. With decoding encoding offloaded the graphics engine and the cpu are free for other operations. Nvidia gpus beginning with.

This means that a. The encoder is supported in many streaming and recording programs such as wirecast open broadcaster software obs and bandicam and also works with share game capture which. Hevc s main advantage over h 264 is that it offers roughly double the compression ratio for the same quality. It basically confirms that nvidia ga102 and ga104 gpus will decode the new av1 open format up to 10 bit and 8kx8k resolution.

Nvidia announced the next generation geforce 30 series consumer gpus at a geforce special event on september 1 2020.
