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:

Hardware Accelerated Video Processing

There is hardware support for image processing functions such as De-interlacing, Film

cadence detection, Advanced Video Scaler (AVS), detail enhancement, gamut

compression, HD adaptive contrast enhancement, skin tone enhancement, total color

control, Chroma de-noise, SFC (Scalar and Format Conversion), memory compression,

Localized Adaptive Contrast Enhancement (LACE), spatial de-noise, Out-Of-Loop De-

blocking (from AVC decoder), 16 bpc support for de-noise/de-mosaic.

The HW video processing is exposed by the graphics driver using the following APIs:

• Direct3D* 9 Video API (DXVA2).

• Direct3D* 11 Video API.

• OneVPL

• MFT (Media Foundation Transform) filters.

• Intel

Graphics Control Library

• Intel VA API

NOTE

Not all features are supported by all the above APIs. Refer to the relevant

documentation for more details.

Hardware Accelerated Transcoding

Transcoding is a combination of decode, video processing (optional) and encode. Using

the above hardware capabilities can accomplish a high-performance transcode

pipeline. There is not a dedicated API for transcoding.

The processor graphics supports the following transcoding features:

• High performance high quality flexible encoder for video editing, video archiving.

• Low-power low latency encoder for video conferencing, wireless display, and game

streaming.

• Lossless memory compression for media engine to reduce media power.

• High-quality Advanced Video Scaler (AVS)

• Low power Scaler and Format Converter.

Platform Graphics Hardware Feature

Hybrid Graphics

Microsoft* Windows* operating system enables the Windows* Hybrid graphics

framework wherein the GPUs and their drivers can be simultaneously utilized to

provide users with the benefits of both performance capability of discrete GPU (dGPU)

and low-power display capability of the processor GPU (iGPU). For instance, when

there is a high-end 3D gaming workload in progress, the dGPU will process and render

the game frames using its graphics performance, while iGPU continues to perform the

display operations by compositing the frames rendered by dGPU. We recommend that

OEMS should seek further guidance from Microsoft* to confirm that the design fits all

the latest criteria defined by Microsoft* to support HG.

Microsoft* Hybrid Graphics definition includes the following:

1. The system contains a single integrated GPU and a single discrete GPU.

2. It is a design assumption that the discrete GPU has a significantly higher

performance than the integrated GPU.

3. Both GPUs shall be physically enclosed as part of the system.

a. Microsoft* Hybrid DOES NOT support hot-plugging of GPUs

b. OEMS should seek further guidance from Microsoft* before designing systems

with the concept of hot-plugging

4. Starting with Windows*10 Th1 (WDDM 2.0), a previous restriction that the

discrete GPU is a render-only device, with no displays connected to it, has been

removed. A render-only configuration with NO outputs is still allowed, just NOT

required.
