2.4 Processor Graphics
The processor graphics is based on Gen 9 LP (generation 9 Low Power) graphics core
architecture that enables substantial gains in performance and lower-power
consumption over prior generations. Gen 9 LP architecture supports up to 48 Execution
Units (EUs) with On-Package Cache 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. Gen 9 LP 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 analytic 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.
The Display Engine handles delivering the pixels to the screen. GSA (Graphics in
System Agent) is the primary channel interface for display memory accesses and PCI-
like traffic in and out.
The display engine supports the latest display standards such as eDP* 1.4, DP* 1.2,
HDMI* 1.4, HW support for blend, scale, rotate, compress, high PPI support, and
advanced SRD2 display power management.

2.4.2 Media Support (Intel
®
QuickSync and Clear Video
Technology HD)
Gen 9 LP implements multiple media video codecs in hardware as well as a rich set of
image processing algorithms.
Note: All supported media codecs operate on 8 bpc, YCbCr 4:2:0 video profiles.
