SAGV (System Agent Geyserville) is a way by which the processor can dynamically scale the work point (V/F), by applying DVFS (Dynamic Voltage Frequency Scaling) based on memory bandwidth utilization and/or the latency requirement of the various workloads for better energy efficiency at System-Agent. SAGV transitions controlled by Pcode Heuristics, periodically evaluating the utilization of memory and IA/GFx cores..

SA Speed Enhanced Speed Steps (SA-GV) and Gear Mode Frequencies

Technology	DDR Maximum Rate [MT/s]	SAGV-LowBW	SAGV-MedBW	SAGV-HighBW	SAGV- High Performance
LPDDR5x	8533	2400 G4	4800 G4	6400 G4	8533 G4
Notes: Intel® Core™ Ultra 200V Series Processor supports dynamic gearing technology where the Memory Controller can run 1:4 (Gear-4 mode) ratio of DRAM speed. The gear ratio is the ratio of DRAM speed to Memory Controller Clock . MC Channel Width equal to DDR Channel width multiply by Gear Ratio. SA-GV modes: LowBW- Low frequency point, Minimum Power point. Characterized by low power, low BW, high latency. The system will stay at this point during low to moderate BW consumption. MedBW - Tuned for balance between power & performance. HighBW - Characterized by high power, low latency, moderate BW also used as RFI mitigation point. MaxBW/Lowest latency Lowest Latency point, low BW and highest power.

DDR Frequency Shifting

DDR interfaces emit electromagnetic radiation which can couple to the antennas of various radios that are integrated in the system, and cause radio frequency interference (RFI). The DDR Radio Frequency Interference Mitigation (DDR RFIM) feature is primarily aimed at resolving narrowband RFI from LPDDR5/x technologies for the Wi-Fi* high and ultra-high bands (~5-7 GHz) . By changing the DDR data rate, the harmonics of the clock can be shifted out of a radio band of interest, thus mitigating RFI to that radio. This feature is working with SAGV on, the 3rd SAGV point is used as RFI mitigation point
