Intel Quick Sync Video is Intel's hardware video encoding and decoding technology, which is integrated into some Intel CPUs. The name "Quick Sync" refers to the use case of quickly transcoding ("syncing") a video from, for example, a DVD or Blu-ray Disk to a format appropriate to, for example, a smartphone. Quick Sync was introduced with the Sandy Bridge CPU microarchitecture on 9 January 2011.
Quick sync has been praised for being very fast.[1] A benchmark from Tom's Hardware showed that it could encode a 449 MB 4 minute 1080p file to 1024×768 in 22 seconds. The same encoding using only software took 172 seconds. The same encoding took 83 or 86 seconds GPU-assisted, using a Nvidia GeForce GTX 570 and a AMD Radeon HD 6870 respectively, both of which are contemporary high end GPUs.[2] Unlike video encoding on a general-purpose GPU, Quick Sync is an application-specific integrated circuit. This allows for faster and more power efficient video processing.[3] [
