Active power management support using L0s/L1 state.

4.6

Integrated Graphics Power Management

4.6.1

Intel® Display Power Saving Technology 5.0

(Intel® DPST 5.0)

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.

4.6.2

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

AXG

) into a lower voltage state (0.3 V).The render frequency clock will

shut down.

4.6.3

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® Smart 2D Display Technology (Intel® S2DDT)

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.
