AMD has released an official statement about the power draw issue imposed by AMD RX 480 graphics card.
We promised an update today (July 5, 2016) following concerns around the Radeonโข 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. Weโre pleased to report that this driverโRadeon Software 16.7.1โis now undergoing final testing and will be released to the public in the next 48 hours.
In this driver weโve implemented a change to address power distribution on the Radeon RX 480 โ this change will lower current drawn from the PCIe bus.
Separately, weโve also included an option to reduce total power with minimal performance impact. Users will find this as the โcompatibilityโ UI toggle in the Global Settings menu of Radeon Settings. This toggle is โoffโ by default.
Finally, weโve 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 โcompatibilityโ toggle.
AMD is committed to delivering high quality and high performance products, and weโll continue to provide users with more control over their productโs performance and efficiency. We appreciate all the feedback so far, and weโll continue to bring further performance and performance/W optimizations to the Radeon RX 480.
