True Performance Of The Radeon RX 480 Examined

Page 2 : Fallout 4, Witcher 3 & Warhammer Results, Conclusion

Contents

Fallout 4 (1920 x 1080)

This chart shows you the minimum and maximum frame rates, as well as the average frame rate, FRAPS recorded in Fallout 4.

In Fallout 4, the new Radeon Software 16.7.1 driver boosted the average frame rate enough to make up for the drop in performance from the reduced power consumption.

 

The Witcher 3 (1920 x 1080)

This chart shows you the minimum and maximum frame rates, as well as the average frame rate, FRAPS recorded in The Witcher 3.

In The Witcher 3, the performance boost was substantial enough to give the Radeon RX 480 [Amazon] a small 1.3% boost in average frame rate, even with the Compatibility Mode triggered.

 

Total War : Warhammer (1920 x 1080)

This chart shows you the minimum and maximum frame rates, as well as the average frame rate, recorded by the Total War : Warhammer benchmark.

Surprisingly, the Radeon Software 16.7.1 driver did even better in Total War : Warhammer. Even with the reduced power consumption, the Radeon RX 480 [Amazon] received a nice 2.2% boost in the average frame rate!

Conclusion

The Radeon Software 16.7.1 driver does two things – reprogram the Radeon RX 480‘s power controller so it will pull more current from the 6-pin PCI Express power cable, and less from the PCI Express bus. This fix does not reduce performance. However, it still means that the Radeon RX 480 [Amazon] will exceed its rated 150 W TDP.

The higher TDP should not cause any concerns normally. However, those want their Radeon RX 480 [Amazon] to adhere to the rated 150 W TDP can enable the new Compatibility Mode switch in Radeon Settings. This reduces the Radeon RX 480‘s TDP to 150 W.

The reduction in power consumption reduces performance, of course. But for all of the furore over the Radeon RX 480 power draw controversy, it looks like the performance boost that the Radeon RX 480 [Amazon] received from the higher-than-rated TDP was less than 4%.

We will be correcting our AMD Radeon RX 480 Review to reflect this change. Yes, 4% may be small, but it is still a significant change, and we have to be accurate.

The good news though is that the small drop in performance is virtually offset by performance optimisations for the AMD Polaris architecture in the new Radeon Software 16.7.1 driver. So if you are a Radeon RX 480 user, go get it now!
