Starting early next month, we'll see the first BIOS updates with AGESA 1180 for AMD 400-series and 500-series motherboards. The big new feature is Precision Boost Overdrive 2, it promises to regulate the curve to precisely and dynamically calculate the exact voltage required for specific workloads.
While typical undervolting optimizes for the worst case scenario, Precision Boost Overdrive 2 features adaptive undervolting. The tool will rely on the workload, temperature socket limits, etc to adapt the voltage as require. It can do this 1,000 times per second.
The Curve Optimization tool will be part of AMD’s Precision Boost Overdrive toolkit, meaning that using it will invalidate the warranty on the hardware, however AMD knows that a number of its user base loves to overclock or undervolt to get the best out of the hardware. The company states that this adaptive methodology will allow for performance gains in both single-thread and multi-thread workloads, as opposed to a standard voltage offset, which they say only really helps with multi-thread examples.
In terms of performance, AMD says Precision Boost Overdrive 2 can give 2 percent higher single-threaded performance and up to 10 percent higher multi-threaded performance for the Ryzen 9 5950X.
