9.0 Graphics
Processor Graphics
The processor graphics is based on X
e
graphics core architecture that enables
substantial gains in performance and lower-power consumption over prior generations.
X
e
architecture supports up to 96 Execution Units (EUs) depending on the processor
SKU.
The processor graphics architecture delivers high dynamic range of scaling to address
segments spanning low power to high power, increased performance per watt, support
for next generation of APIs. X
e
scalable architecture is partitioned by usage domains
along Render/Geometry, Media, and Display. The architecture also delivers very low-
power video playback and next generation analytics and filters for imaging related
applications. The new Graphics Architecture includes 3D compute elements, Multi-
format HW assisted decode/encode pipeline, and Mid-Level Cache (MLC) for superior
high definition playback, video quality, and improved 3D performance and media.
Media Support (Intel
®
QuickSync and Clear Video Technology
HD)
X
e
implements multiple media video codecs in hardware as well as a rich set of image
processing algorithms.
NOTE
HEVC and VP9 support additional 10bpc, YCbCr 4:2:2 or 4:4:4 profiles. Refer
additional detail support matrix.
Hardware Accelerated Video Decode
X
e
implements a high-performance and low-power HW acceleration for video decoding
operations for multiple video codecs.
The HW decode is exposed by the graphics driver using the following APIs:
• Direct3D* 9 Video API (DXVA2)
• Direct3D11 Video API
• Direct3D12 Video API
• Intel Media SDK
• MFT (Media Foundation Transform) filters.
• Intel VA API
X
e
supports full HW accelerated video decoding for AVC/HEVC/VP9/JPEG/AV1.

NOTE
Video playback best performance can be achieved by enabling display MPO with
minimized EU workloads. In some test scenarios, it may act differently.
For example, 8k playback on less than 8k monitors, in non-full screen mode or some
UI operations and unexpected end user behaviors etc. - These will hit MPO limitation
or simply applications do not use MPO.
Then graphics driver need to use EU for rendering/composition, and 8K E2E playback
has dependency on EU counts capability.
Expected performance: More than 16 simultaneous decode streams @ 1080p.
NOTE
Actual performance depends on the processor SKU, content bit rate, and memory
frequency. Hardware decode for H264 SVC is not supported.
Hardware Accelerated Video Encode
Gen12 implements a low-power low-latency fixed function encoder and a high-quality
customizable encoder with hardware assisted motion estimation engine which
supports AVC, MPEG-2, HEVC, and VP9.
The HW encode is exposed by the graphics driver using the following APIs:
