The problem is described as the Radeon RX 480 drawing excess current from the PCIe bus, and we've already written about it a few times this week. It seems to be a burning topic for  RX 480 fans and owners. Nick has already written about the issue and stated  the fix driver is coming.  Now we have some more details. 

We would expect to see the Radeon Software 16.7.1 either today or latest tomorrow, depending which time zone  you in. The driver will implement a change to address power distribution on the Radeon RX 480. The company claims that this change will lower current drawn from the PCIe bus. AMD claims that it managed to reduce the total power with minimal impact on performance.

The new driver will yield performance uplifts in popular game titles of up to 3 percent. From the conversation that we had with our international colleagues, we came  to the conclusion that there is a very small number of review samples that have been affected. Marc Sauter the Senior Editor - Hardware & Technology at Golem.de has compiled a list of reviews that were not affected by the problem.

The whole statement from AMD -RTG is below.

We (Radeon Technology Group) 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. We’re pleased to report that this driver—Radeon Software 16.7.1—is now undergoing final testing and will be released to the public in the next 48 hours.

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

Separately, we’ve 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, we’ve 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 we’ll continue to provide users with more control over their product’s performance and efficiency. We appreciate all the feedback so far, and we’ll continue to bring further performance and performance/W optimizations to the Radeon RX 480.
