Radeon Software 16.7.1
Following the Radeon RX 480 power draw controversy, AMD released the Radeon Software 16.7.1 driver. This is a non-WHQL driver that was pushed out quickly to fix the Radeon RX 480‘s excessive power draw from the PCI Express bus. However, it also comes with a 3% boost in performance for the Polaris architecture.
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.
So we decided to take a look at the performance improvements it delivers in the Radeon RX 480 [Amazon]. We also took a look at how it affects the AMD Radeon R9 380 graphics card, which is based on the previous-generation Fiji architecture. Check it out!
3DMark (1920 x 1080)
We started testing the graphics cards using 3DMark at the most common gaming resolution – 1920 x 1080.
The Radeon RX 480 [Amazon] received a 3.15% boost in the Overall Score, a 3.77% boost in the Graphics Score and a 3% boost in the Combined Score. Very nice! The Radeon R9 380, however, did not benefit from the newer Radeon Software 16.7.1 driver at all.
The frame rate breakdown shows the Radeon RX 480 [Amazon] edging even further away from its predecessor, the Radeon R9 380. It is now 44-48% faster than the Radeon R9 380, thanks to the Radeon Software 16.7.1 driver.
3DMark (2560 x 1440)
At this higher resolution, the Radeon RX 480 [Amazon] received a smaller performance boost of 2.6% in the Overall Score, 2.9% in the Graphics Score and 2.3% in the Combined Score. The Radeon R9 380‘s performance actually suffered slightly (by 1%) with the Radeon Software 16.7.1 driver.
The small boost in performance from the Radeon Software 16.7.1 driver only gave the Radeon RX 480 [Amazon] a small 0.5-1 fps boost in frame rate. Coupled with the slight drop in the Radeon R9 380‘s performance, the Radeon RX 480 is now 40-50% faster than the Radeon R9 380.
3DMark (3840 x 2160)
For some reason, the Radeon Software 16.7.1 driver caused the benchmark to fail while running on the Radeon R9 380. However, we can see that it gives the Radeon RX 480 [Amazon] is a small 2.4% boost in the Overall Score, a 2.3% boost in the Graphics Score and a 2.85% boost in the Combined Score.
