AMD releases a new statement regarding the RX 480's power issues


AMD releases a new statement regarding the RX 480's power issues, stating that they will be releasing a new driver within the next 48 hours which will lower PCIe power draw and enhance performance by up to 3%. 

AMD's new Radeon Software Crimson 16.7.1 driver will automatically lower the power draw from the PCIe slot, adding a new "compatibility" mode that will lower power draw further with a minimal decrease in performance. This new driver will also implement several Polaris specific optimisation which will enhance the GPUs performance in popular gaming titles by up to 3%, more than offsetting the performance impact of "compatibility" mode. 


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. 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%. 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.

  AMD releases a new statement regarding the RX 480's power issues


One of the changes that AMD has made with Polaris is the ability to change a lot of the aspects of the GPU through software, allowing AMD to update the GPUs memory compression methods and several other aspects of the GPU over time in order to improve the performance of their Polaris GPUs in the future.

AMD plans to continue to improve the RX 480's performance per watt over time with specific optimisations in order to deliver consumers with the best possible experience with AMD hardware.

AMD said they were going to keep improving on the RX 480, and they did. They also fixed the issue with power distribution AND provided the option to draw a lot less power for minimal negative, or even a positive performance change.Quote

They are more than likely to switch where the power comes from. Instead of the slot, transfer it to the 6pin.. Which is fine as nearly all are overbuilt for extra power draw anyway and if it gets to dangerous, it has over current protection, unlike the motherboard. But I doubt it. Just look at the 295x2. That drew more than what it was rated for, significantly more tooQuote

I'm more concerned about them wiring the 6 pin like it was 8 pin and how its totally isolated from the pci express side the middle pin should be used to detect plug yet it is actually a ground and thus capable of dealing with over 200wQuote

Regarding this whole thing people called "Powergate" first of all, at least it was an oversight on AMD's side and actually fixable (at least what they say for now) with a driver/bios update. Good for them. At least we can suppose it wasn't on their knowing that this issue would occur, like NVIDIA did with the 970.

How do we know that drawing that much power through the PCIe was such a bad thing, most motherboards out there are designed to handle SLI and crossfire and should have circuitry able to handle the powerdraw without getting damaged.

I would not call the way the used the 6 pin as an oversight at all. it is not connected to the correct standard.Quote
