DivX HEVC Hardware Acceleration: Test Results on Intel Skylake

Enabling DivX Accelerated Options

The DivX Accelerated program vigorously tests and validates that a particular chipset is optimized for decoding and/or encoding of DivX video formats in DivX Software. Until now, DivX Software has offered DivX Accelerated functionality for encoding and decoding of AVC video (H.264/MKV and MP4) and decoding of AVI video (DivX/MPEG-4 ASP).

As of the DivX 10.4 software release, Intel® Quick Sync Video has been enabled natively to the new DivX Player to enable hardware accelerated decoding of HEVC video on computers with supported Intel chipsets. You can enable the DivX Accelerated option in Player’s Preferences.

This is a significant milestone to improve the experience of playing HEVC video, especially at high resolutions like 4K. This experience is particularly improved on the newly released 6th Generation Intel Core processor family (“Skylake”), which uses the dedicated media processing capabilities of Intel Graphics Technology.

The 4th and 5th Generations Intel Core Processor families (“Haswell” and “Broadwell”) offer a form of improved HEVC video playback through partial hardware acceleration support. However, the 6th Generation Intel processors offers full fixed-function decode through Intel® Quick Sync Video that offers high performance decode while also enabling the processor to complete other tasks, improving overall PC performance and responsiveness.

Our preliminary tests below performed on an engineering-build Skylake 2-in-1 laptop confirm these findings. In our testing of 4K HEVC video for CPU Performance, Memory Usage and Frames per Second, all were significantly improved when DivX Accelerated was on compared to the same tests with DivX Accelerated turned off.
