AMD has announced continued work on tweaking software support for its latest Ryzen processors and its SenseMI technology, building a new power plan for Windows 10 which helps to improve responsiveness.
AMD has released a new 'Balanced' power plan for Windows 10 which it claims dramatically improves responsiveness on Ryzen chips without harming overall power draw.
First unveiled by the company in December last year
, SenseMI is the name given to a suite of technologies built into the company's Zen-architecture Ryzen chips and designed to improve power efficiency while boosting on-demand performance. SenseMI is split into five core technologies: Pure Power, which comprises more than 100 embedded sensors which monitor the chips' voltage, power draw, and temperature at an individual-component level; Precision Boost, which modifies the current clock speed in 25MHz increments at a 1,000Hz polling rate; Neural Net Prediction and Smart Prefetch, which aim to more accurately predict the upcoming instructions and data requirements of programs compared with existing algorithms; and Extended Frequency Range (XFR), which automatically - though to a minor extent - boosts the chips' clock speed above their default maximum when adequately cooled.
In theory, SenseMI should add up to considerable power savings without sacrificing performance - but only if the host operating system knows how to make sense of the platform. That's an improvement AMD, in Robert Hallock's latest community update
, claims to have made in the form of a new power plan for Windows 10 which improves the on-demand performance without harming power draw.
Installing the power plan, AMD has claimed following internal testing, can improve responsiveness to a point where the default 'Balanced' plan can now rival the all-out 'High Performance' plan - yet still clock down and save power when you're not running CPU-intensive applications. For now, the power plan is a manual download; AMD has indicated it's waiting for user feedback on power usage and responsiveness before making it, or a modified version thereof, an automatically installed part of its official chipset drivers.
