![]() HEVC hardware encoding quality has also been improved. Version 7 (Ice Lake) The Ice Lake microarchitecture implementation adds VP9 8-bit and 10-bit decoding and encoding acceleration, H.265/HEVC 8-bit and 10-bit decoding and encoding acceleration with 4:2:2 and 4:4:4 chroma subsampling, HDR10 Tone Mapping and Open Source Media Shaders. Version 6 (Kaby Lake, Coffee Lake, Whiskey Lake, Comet Lake) The Kaby Lake, Coffee Lake, Whiskey Lake and Comet Lake microarchitectures implementation adds full fixed-function H.265/HEVC 10-bit 4:2:0 decoding and encoding acceleration, and full fixed-function VP9 8-bit and 10-bit decoding acceleration and 8-bit encoding acceleration. Version 5 ( Skylake) The Skylake microarchitecture implementation adds a full fixed-function H.265/HEVC 8-bit 4:2:0 decoding and encoding acceleration, hybrid and partial HEVC 10-bit decoding acceleration, JPEG encoding acceleration for resolutions up to 16,000×16,000 pixels, and partial VP9 decoding and encoding acceleration. Also, it has two independent bit stream decoder (BSD) rings to process video commands on GT3 GPUs this allows one BSD ring to process decoding and the other BSD ring to process encoding at the same time. Version 4 ( Broadwell) The Broadwell microarchitecture implementation adds VP8 hardware decoding. An open-source hybrid driver was developed which supports partial VP8 encoding and VP9 decoding acceleration under Linux by utilizing both the integrated GPU and CPU. Version 3 ( Haswell) The Haswell microarchitecture implementation adds H.262/MPEG-2 Part 2 encoding acceleration. Version 2 (Ivy Bridge, Bay Trail) The Ivy Bridge microarchitecture included a "next-generation" implementation of Quick Sync. ![]() It adds H.264/AVC encoding and VC-1 decoding acceleration. Version 1 (Sandy Bridge) Quick Sync was initially built into some Sandy Bridge CPUs, but not into Sandy Bridge Pentiums or Celerons. The older Clarkdale microarchitecture had hardware video decoding support, but no hardware encoding support it was known as Intel Clear Video. Quick Sync was first unveiled at Intel Developer Forum 2010 (September 13) but, according to Tom's Hardware, Quick Sync had been conceptualized five years before that. Ī 2012 evaluation by AnandTech showed that QuickSync on Intel's Ivy Bridge produced similar image quality compared to the NVENC encoder on Nvidia's GTX 680 while performing much better at resolutions lower than 1080p. However, Quick Sync could not be configured to spend more time to achieve higher quality, whereas x264 improved significantly when allowed to use more time using the recommended settings. The eighth annual MPEG-4 AVC/H.264 video codecs comparison showed that Quick Sync was comparable to x264 superfast preset in terms of speed, compression ratio and quality (SSIM) tests were performed on an Intel Core i7 3770 (Ivy Bridge) processor. Like most desktop hardware-accelerated encoders, Quick Sync has been praised for its speed. Quick Sync Video is available on Core i3, Core i5, Core i7, and Core i9 processors starting with Sandy Bridge, and Celeron & Pentium processors starting with Haswell. 6.1 Hardware video hardware technologies.
