Curve Optimizer
Complementing the power of PBO is the Curve Optimizer feature. This advanced tuning tool allows users to fine-tune the voltage-frequency curve for each individual CPU core, effectively undervolting the processor for improved efficiency and thermals.
The Curve Optimizer works by applying a negative offset to the core’s voltage, reducing the amount of power required to achieve a given clock speed. This not only lowers operating temperatures but can also lead to higher sustained boost clocks, as the processor is no longer hitting its power or thermal limits as quickly.
To utilize the Curve Optimizer, users must again delve into their BIOS settings. Here, they can either apply a global, all-core offset or adjust the values on a per-core basis, tailoring the tuning to the unique characteristics of their specific CPU.
Performance Monitoring
Effective tuning of PBO and the Curve Optimizer requires careful monitoring of system performance and telemetry. Tools like HWiNFO64 and Ryzen Master provide a wealth of data, including CPU utilization, temperatures, voltages, and power consumption. By closely tracking these metrics, users can identify optimal settings and ensure system stability.
Benchmarking applications, such as Cinebench R23 and 3DMark, also play a crucial role in quantifying the performance gains achieved through PBO and Curve Optimizer tuning. These standardized tests can help users objectively measure the improvements in both single-threaded and multi-threaded workloads.
