The net performance value is impressive: what we're calling the Gen9+ graphics engine (improved from Skylake's Gen9 nomenclature) supports up to eight simultaneous 4Kp30 AVC and HEVC streams and it handles more demanding real-time 4Kp60 HEVC decode operations at 120 Mb/s.

Intel also added HDR (High Dynamic Range) support to its VQE engine, which supports video processing and content enhancement features like color correction, color enhancement, skin tone enhancement, and noise reduction.
Skylake employed a hybrid implementation that used both the CPU and GPU to process some codecs, but Kaby Lake's fully hardware-accelerated processing reduces CPU utilization, and thus power consumption, during video playback.
Kaby Lake requires 0.5 watts on average, while. According to the website, jellyfish-400-mbps-4k-uhd-hevc-10bit.mkv is the higher. This graphic compares the amount of power used by Skylake’s CPU and graphics engine to render 4K/10-bit HEVC video, versus Kaby Lake. Here is my bonus requirements (if the price worth it) : Can read fluently higher videos than jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv.

Intel also adds full hardware support for HEVC 10-bit decode/encode, VP9 8/10-bit decode, and VP9 8-bit encode. This is the most used format of all my 4K videos. The Multi-format Codec (MFX) serves multiple functions, such as support for legacy VP8 and AVC codecs. ffmpeg kaby-lake transcode I have about 30 gigabytes of video (mostly MP4, some MKV and webm) I need to transcode to 8-bit VP9 with Free Lossless Audio Codec (FLAC) audio in an MKV container from various input codecs (AAC audio H264, VP8, H265/HEVC, and probably some other video codecs). Each collection of three subslices functions as its own larger slice and Intel can vary the number of slices to adjust performance in various SKUs. During a gaming session, for instance, the subslices handle the rendering work while the MFX engine tackles the encoding/decoding tasks. These units sit outside of the rendering pipeline and operate independently of the subslices, increasing parallelism. Intel focused on targeted optimizations to the MFX (decode/encode) and VQE engines, which it outlines in green. The three subslices in the middle house the EUs, cache, 3D sampler, and media samplers, and they share the resources to the left (un-slice) while handling the bulk of the rendering work.
The company employs the same basic Gen9 graphics core architecture that it used with the Skylake platform, albeit with a few enhancements. The key to boosting performance during heavy workloads requires decoupling some of the processes, such as encoding and decoding, from the main render pipeline.
