The Intel® Visual Compute Accelerator (Intel® VCA)

The Intel® Visual Compute Accelerator (Intel® VCA) is one of its kind product that encapsulates various other innovative Intel products. It combines the capabilities of the Intel® Iris® Pro graphics within the Intel® Xeon® processor E3-1200 v4 and the power of the Intel® Xeon® processor E5-2600 v3 family. This PCIe add-in card is designed around visual computing workloads and apart from many simultaneous Advanced Video Coding (AVC) jobs can handle the high-end 4K/High- Efficiency Video Coding (HEVC) transcoding jobs as well.


With each processor supporting a maximum 32GB of RAM, not only can it satisfy the requirements for 4K video streaming, it can also effectively improve the encoding and transcoding speeds of 3D graphics, VR content, and so on. If we look at the usability aspect of it, Intel® VCA can be inserted into the PCIe interface used by traditional graphics cards and can be directly deployed on servers based on the Intel® Xeon® processor family of products to enhance server video processing capabilities.

The video processing capabilities of edge data centres can be greatly increased, thanks to the deployment of Intel® VCA. It also enables video and OTT services to be deployed on nearby edge nodes. The deployment of vCDN nodes on virtual machines partitioned on edge data centre servers provides high-efficiency video encoding, decoding, and transcoding capabilities for a series of video applications including IPTV.

The vCDN 4Khigh-definition video service received good user feedback in China Telecom’s proof-of-concept project. As per Intel’s H.264 to H.265 video transcoding tests, the Mean Opinion Score (MOS) and image lag rate reached the expected objectives of the testing.
