Processor Graphics Core Power Savings Technologies
Intel® Graphics Dynamic Frequency
Intel® Turbo Boost Technology 2.0 is the ability of the processor IA cores and graphics (Graphics Dynamic Frequency) cores to opportunistically increase frequency and/or voltage above the guaranteed processor and graphics frequency for the given part. Intel® Graphics Dynamic Frequency 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 IA 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. Intel® Graphics Dynamic Frequency requires BIOS support. Additional power and thermal budget should be available.
Intel® Graphics Render Standby Technology (Intel® GRST)
Intel® Graphics Render Standby Technology is a technique designed to optimize the average power of the graphics part. The Graphics Render engine will be put in a sleep state, or Render Standby (RS), during times of inactivity or basic video modes. While in Render Standby state, the graphics part will place the VR (Voltage Regulator) into a low voltage state. Hardware will save the render context to the allocated context buffer when entering RS state and restore the render context upon exiting RS state.
Dynamic FPS (DFPS)
Dynamic FPS (DFPS) or dynamic frame-rate control is a runtime feature for improving power-efficiency for 3D workloads. Its purpose is to limit the frame-rate of full screen 3D applications without compromising on user experience. By limiting the frame rate, the load on the graphics engine is reduced, giving an opportunity to run the Processor Graphics at lower speeds, resulting in power savings. This feature works in both AC/DC modes.
