NVIDIA GeForce Now is made possible by leveraging NVENC in the datacenter and streaming the result to end clients

Hardware Based Decoder and Encoder

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.

GPU hardware accelerator engines for video decoding (referred to as NVDEC) and video encoding (referred to as NVENC) support faster than real-time video processing which makes them suitable to be used for transcoding applications, in addition to video playback. NVIDIA’s newest GPU architecture, Ada, features up to 3x NVENC. Video Codec SDK 12.0 will support evenly distributing loads across multiple encoders, enabling real-time 8k60 encoding for AV1 and HEVC formats.

NVENC - Hardware-Accelerated Video Encoding

Introducing AV1 encoding with Video Codec SDK 12.0 on NVIDIA’s Ada architecture. AV1 is the state of the art video coding format that supports higher quality with better performance compared to H.264 and HEVC. On Ada, multiple NVENC coupled with AV1 enables encoding 8k video at 60fps alongside a higher number of concurrent sessions. With complete encoding (which is computationally complex) offloaded to NVENC, the graphics engine and the CPU are free for other operations. For example, in a game recording and streaming scenario like streaming to Twitch.tv using Open Broadcaster Software (OBS), encoding being completely offloaded to NVENC makes the graphics engine bandwidth fully available for game rendering.

NVENC enables streaming applications at high quality and ultra-low latency without utilizing the CPU, encoding at very high quality for archiving, OTT streaming, web videos, and encoding with ultra-low power consumption per stream (Watts/stream)

Note: The graph showcases performance on NVIDIA datacenter T4, A10 and L40.

Bitrate savings are BD-BR based on PSNR, average across a large variety of content (several hundreds of video clips), using FFmpeg.

Only datacenter GPUs are presented on the benchmark graphs for clarity but equivalent workstation GPU with same architecture performs similarly​.

NVDEC - Hardware-Accelerated Video Decoding

NVIDIA GPUs contain a hardware-based decoder (referred to as NVDEC) which provides fully-accelerated hardware-based video decoding for several popular codecs. With complete decoding offloaded to NVDEC the graphics engine and the CPU are free for other operations. NVDEC supports much faster than real-time decoding which makes it suitable to be used for transcoding applications, in addition to video playback applications.

NVDECODE API enables software developers to configure this dedicated hardware video decoder. This dedicated accelerator supports hardware-accelerated decoding of the following video codecs on Windows and Linux platforms: MPEG-2, VC-1, H.264 (AVCHD), H.265 (HEVC), VP8, VP9 and AV1 (see table below for codec support for each GPU generation).
