Processor—Power Management

4.6Graphics Power Management

4.6.1Intel® Rapid Memory Power Management (Intel® RMPM)

Intel Rapid Memory Power Management (Intel RMPM) conditionally places memory into self-refresh when the processor is in package C3 or deeper power state to allow the system to remain in the lower power states longer for memory not reserved for graphics memory. Intel RMPM functionality depends on graphics/display state (relevant only when processor graphics is being used), as well as memory traffic patterns generated by other connected I/O devices.

4.6.2Graphics 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. 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 idleness condition is met, the processor graphics will program the graphics render engine internal power rail into a low voltage state.

4.6.3Intel® Graphics Dynamic Frequency

Intel Graphics Dynamic Frequency Technology is the ability of the processor and graphics cores to opportunistically increase frequency and/or voltage above the guaranteed 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 try to place the graphics engine in the most energy efficient P-state.
