Video Core Next
Video Core Next is AMD's brand for its dedicated video encoding and decoding hardware core. It is a family of hardware accelerator designs for encoding and decoding video, and is built into AMD's GPUs and APUs since AMD Raven Ridge, released January 2018.
Background[edit]
Video Core Next is AMD's successor to both the Unified Video Decoder and Video Coding Engine designs,[1] which are hardware accelerators for video decoding and encoding, respectively. It can be used to decode, encode and transcode ("sync") video streams, for example, a DVD or Blu-ray Disc to a format appropriate to, for example, a smartphone. Unlike video encoding on a CPU or a general-purpose GPU, Video Core Next is a dedicated hardware core on the processor die. This application-specific integrated circuit (ASIC) allows for more power-efficient video processing.[2][3]
Support[edit]
Video Core Next supports: MPEG-2 Decode, MPEG-4 Decode, VC-1 Decode, H.264/MPEG-4 AVC Encode/Decode, HEVC Encode/Decode, and VP9 Decode.[4]
VCN 2.0 is implemented with Navi products and the Renoir APU. The feature set remains the same as VCN 1.0. VCN 3.0 is implemented with Navi 2 products.[5]
