AMD has just released a new set of chipset drivers for Ryzen that promises to improve performance and power efficiency through clever Ryzen specific optimizations to Windows 10’s power management and scheduler. The new chipset driver introduces an AMD Ryzen optimized “Balanced Plan” that replaces Windows 10’s default power plan.

AMD Introduces Ryzen Optimized Windows 10 Power Plan

The new optimizations boost performance by cutting some of Windows 10’s aggressive core parking features that put lightly used cores in a sleep state and introduce added latency when those cores are woken up again to perform a task.

The update also significantly cuts the latency produced by the old Windows power plan produced by slow core transition phases from low power to a high performance state. AMD’s latest chipset drivers strips these scheduling and power state responsibilities away from the operating system and hands them to Ryzen’s internal AI network dubbed SenseMI.

SenseMI is a network of technologies built in the Ryzen hardware that enable the underlying micro-architecture to auto-regulate itself.  Excecuting very fast and fine adjustments to voltage and frequency at any given millisecond to maximize performance and power efficiency. The update removes the overbearing layer of software based power management built into Windows and allows AMD’s SenseMI technology to directly manage, as it should, every Ryzen processor to run it at its peak potential.

OK, enough technical gibberish. What exactly are you going to get from this new update in terms of performance. Well the graph below showcases the performance improvement percentage wise in 7 different games with AMD’s new SenseMI driven Balanced Power plan as well as the Windows High Performance plan compared to the old default Windows balanced plan.

System configuration: AMD Ryzen™ 7 1800X, Gigabyte GA-AX370-Gaming5, 2x8GB DDR4-2933, GeForce GTX 1080 (378.92 driver), Windows 10 x64.

So there you have it folks. If you have a Ryzen based Windows 10 machine that you’ve left running with Windows 10’s default balanced power plan then this update is basically a free performance upgrade for you. If you’ve been using your machine with the Windows 10 High Performance plan then this update is a free power efficiency upgrade. You can download the latest chipset drivers directly from AMD’s website, by following this link.

Here’s some of what AMD had to say about the latest update.

Other games that we’ve seen benefit from the new plan include: Total War™: WARHAMMER, Alien: Isolation™, Crysis™ 3, Gears of War™ 4, Battlefield™ 4, Project Cars™ and more. Though not every game behaves in a way where a change in power plans has an impact on the AMD Ryzen™ processor, we’ve long maintained that there are enough games to warrant a change. Today’s findings put a fine point on that, and we’re very excited to get these changes into the hands of our customers starting today!

Installation is simple: just install the latest AMD chipset drivers for Windows 10 64-bit!

After collecting feedback from this community preview, we intend to roll the final power plan into the AMD Chipset drivers for AMD Ryzen processors. The Ryzen Balanced plan will automatically be configured as the default power plan for Ryzen-based Windows 10 PCs. If you’ve already downloaded and installed our new power plan from this blog, the new chipset driver package will ensure you do not encounter duplicate entries.

In short:

  1. The AMD Ryzen™ Balanced power plan still permits aggressive power management. There should be little difference between the OEM Balanced and the Ryzen Balanced plan. We’re interested in your feedback!
  2. Performance of the AMD Ryzen™ Balanced power plan should be on par with the High Performance plan. We’re interested in your feedback on this, too.
  3. Finally, if you see a third-party tool reporting “idle” clocks in the range of 3200-3400MHz, you can be virtually certain that the core is actually sleeping and the tool is simply reporting the last known P-State.
