Radeon Software Crimson 16.7.1 with RX 480 performance and powering improvements

If you’re one of the early adopters of the new Radeon RX 480 reference cards that launched on June 29th, and happen to experience the rare issue of increased PCI-Express power draw, there’s a fix for that now available!

Recently media reported a rare issue of select early Radeon RX 480 reference boards drawing excessive power from the PCI-Express bus under specific circumstances. To fix this AMD has delivered a software-based easy solution for everyone. That is what we present you today, along with some bonus performance improvements!

    • The Radeon™ RX 480’s power distribution has been improved for AMD reference boards, lowering the current drawn from the PCIe bus.
    • A new “compatibility mode” UI toggle has been made available in the Global Settings menu of Radeon Settings. This option is designed to reduce total power with minimal performance impact if end users experience any further issues.  This toggle is “off” by default.
    • 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.

Fixed Issues

    • Radeon™ RX 480 limited PCI-E Bandwidth (PCI-E bandwidth is now at the correct speed on the Radeon™ RX 480) with Radeon Software Crimson Edition 16.7.1.
    • Minor stuttering no longer occurs in Grand Theft Auto V on Radeon™ RX 480 with Radeon Software Crimson Edition 16.7.1.
    • Video corruption will not be observed in DOOM with resolutions above 1920×1080 with Radeon Software Crimson Edition 16.7.1.
    • Hitman™ graphical corruption no longer occurs when the game is set to use DirectX®12 API and using zoom with weapons with Radeon Software Crimson Edition 16.7.1.
    • Display will not exhibit minor flicker on Radeon™ RX 480 when Freesync is enabled on a games launch or exit with Radeon Software Crimson Edition 16.7.1.

The drivers have already been tested by some of the media outlets and PCPer.com reports significant power draw balance changes with 6-pin 12V line now safely drawing more and PCI-Express less. The performance, thanks to further driver optimizations for Polaris architecture, is also better with 16.7.1 despite the powering adjustments made at the same time.
