AMD Driver Update for RX 480 To Fix Power Issue – Radeon Software 16.7.1 Coming in 48 Hours

By

AMD released the following statement regarding the Radeon RX 480 drawing excess current from the PCIe bus. They promised an update on July 5th, but we didn’t get it until 12:20am ET and was sound asleep!

We promised an update today (July 5, 2016) following concerns around the Radeon RX 480 drawing excess current from the PCIe bus. Although we are confident that the levels of reported power draws by the Radeon RX 480 do not pose a risk of damage to motherboards or other PC components based on expected usage, we are serious about addressing this topic and allaying outstanding concerns. Towards that end, we assembled a worldwide team this past weekend to investigate and develop a driver update to improve the power draw. Were pleased to report that this driverRadeon Software 16.7.1is now undergoing final testing and will be released to the public in the next 48 hours.

In this driver weve implemented a change to address power distribution on the Radeon RX 480 this change will lower current drawn from the PCIe bus.

Separately, weve also included an option to reduce total power with minimal performance impact. Users will find this as the compatibility UI toggle in the Global Settings menu of Radeon Settings. This toggle is off by default.

Finally, weve implemented a collection of performance improvements for the Polaris architecture that yield performance uplifts in popular game titles of up to 3%1. These optimizations are designed to improve the performance of the Radeon RX 480, and should substantially offset the performance impact for users who choose to activate the compatibility toggle.

AMD is committed to delivering high quality and high performance products, and well continue to provide users with more control over their products performance and efficiency. We appreciate all the feedback so far, and well continue to bring further performance and performance/W optimizations to the Radeon RX 480.
