AMD has announced they will be introducing Adaptive Undervolting tools for their precision Boost Overdrive software, available for the latest Ryzen 5000 series CPUs. This feature will be made available come launch of AGESA 1180 on 400-series and 500-series motherboards (estimated availability in early December), and will require a BIOS update to enable at the software level. According to AMD, this tool will dynamically calculate the precise amount of voltage required for a given task, analyzing internal sensors (such as workload, temperature, socket limits) and adapting voltage values on the fly at up to 1000 times a second.
AMD says that enabling this feature could lead to up to 2% higher single-thread performance and up to 10% higher multithread performance, as lower temperatures enable the CPU to more aggressively Boost under these conditions. According to AMD, this undervolting technique shows higher gains the higher number of CCDs (and thusly, of cores) that a given CPU has available in silicon.
