Adrenalin 21.8.1 driver decreases power consumption of RDNA 2 GPUs in 4K 60fps video playback

Adrenalin drivers were updated to decrease power consumption by up to 10% in 4K 60fps video playback.The best graphics cards 2021 is a problem that has been present for a while. The Adrenalin driver update decreases power consumption of the RDNA 2 GPUs in 4K 60fps video playback.

AMD drivers have a reputation for being unreliable. The same issue occurred recently with most RDNA2 GPUs, particularly the RX 6600XT. Thanks to ComputerBase for spotting a problem with the RDNA2 GPUs using excessive amounts of electricity.


During YouTube 4K60 playback, they observed that the RX 6600XT used more power than other RDNA2 graphics cards. They decided to do the same test again. The Adrenalin 21.8.1 driver was found to be lowering the temperature. Even with the AMD Radeon RX 6700 XT, there was a substantial reduction in power usage.

As a result, the irregularity in power consumption has been addressed using the most recent drivers. The Navi 22 (RX 6700 XT) outperforms the Navi 21 (RX 6800/6900), while the Navi 23 (RX 6600 XT) outperforms the Navi 22 in terms of efficiency. AMD also made modifications to the 2D behavior, which was observed.

It was previously creating problems with higher refresh rate displays, and even with the newest upgrades, all RDNA GPUs continue to use a significant amount of power. The RX6600 is the sole exception. The problem with YouTube playback has nearly been resolved with the most recent update. The memory clock is no longer set at 8000MHz in the newest drivers, resulting in reduced power usage.

However, with the most recent drivers, the gains are still modest. When the HRD mode was enabled, however, no difference was seen from the prior testing. The RDNA2 GPUs run at maximum speed, which means they use more power.
