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. 
S2DDT is only enabled in single pipe mode.

Intel S2DDT is most effective with:

• Display images well suited to compression, such as text windows, slide shows, and 

so on. Poor examples are 3D games.

• Static screens such as screens with significant portions of the background showing 

2D applications, processor benchmarks, and so on, or conditions when the 
processor is idle. Poor examples are full-screen 3D games and benchmarks that flip 
the display image at or near display refresh rates.

 Graphics Dynamic Frequency Technology is the ability of the processor and 

graphics cores to opportunistically increase frequency and/or voltage above the 
ensured processor and graphics frequency for the given part. Intel

®

 Graphics Dynamic 

Frequency Technology is a performance feature that makes use of unused package 
power and thermals to increase application performance. The increase in frequency is 
determined by how much power and thermal budget is available in the package, and 
the application demand for additional processor or graphics performance. The 
processor core control is maintained by an embedded controller. The graphics driver 
dynamically adjusts between P-States to maintain optimal performance, power, and 
thermals. The graphics driver will always place the graphics engine in its lowest 
possible P-State; thereby, acting in the same capacity as Intel GPMT.

This is a mobile only supported power management feature.

The Intel

®

 DPST technique achieves backlight power savings while maintaining a good 

visual experience. This is accomplished by adaptively enhancing the displayed image 
while decreasing the backlight brightness simultaneously. The goal of this technique is 
to provide equivalent end-user-perceived image quality at a decreased backlight power 
level.

1. The original (input) image produced by the operating system or application is 

analyzed by the Intel

®

 DPST subsystem. An interrupt to Intel

®

 DPST software is 

generated whenever a meaningful change in the image attributes is detected. (A 

meaningful change is when the Intel

®

 DPST software algorithm determines that 

enough brightness, contrast, or color change has occurred to the displaying images 

that the image enhancement and backlight control needs to be altered.)

2. Intel

®

 DPST subsystem applies an image-specific enhancement to increase image 

contrast, brightness, and other attributes.

3. A corresponding decrease to the backlight brightness is applied simultaneously to 

produce an image with similar user-perceived quality (such as brightness) as the 
original image.

Intel

®

 DPST 5.0 has improved the software algorithms and has minor hardware 

changes to better handle backlight phase-in and ensures the documented and validated 
method to interrupt hardware phase-in.
