Intel DPST maintains visual experience by managing display image brightness and
contrast while adaptively dimming the backlight. As a result, the display backlight
power can be reduced by up to 25% depending on Intel DPST settings and system use.
Intel DPST 5.0 provides enhanced image quality over the previous version of Intel
DPST.

Graphics Render C-State

Render C-State (RC6) is a technique designed to optimize the average power to the
graphics render engine during times of idleness of the render engine. RC6 is entered
when the graphics render engine, blitter engine and the video engine have no workload
being currently worked on and no outstanding graphics memory transactions. When
the render engine idleness condition is met: The graphics VR will lower the graphics
voltage rail (V
shut down.

Graphics Performance Modulation Technology

Graphics Performance Modulation Technology (GPMT) is a method for optimizing the
power efficiency in the graphics render engine while continuing to render 3D objects
during battery operation. The GPMT feature will dynamically switch the render
frequency based on the render workload, on power policy, skew, and environmental
conditions.

4.6.4 Intel
Intel S2DDT reduces display refresh memory traffic by reducing memory reads
required for display refresh. Power consumption is reduced by less accesses to the IMC.
Intel S2DDT is most effective with:
•
Display images well suited to compression, such as text windows, slide shows, etc.
Poor examples are 3D games.
•
Static screens such as screens with significant portions of the background showing
2D applications, CPU benchmarks, etc., or conditions when the CPU is idle. Poor
examples are full-screen 3D games and benchmarks that flip the display image at
or near display refresh rates.
