Alongside all of the features mentioned in the patch notes, the new drivers improve power efficiency in non-gaming scenarios. > TechPowerUp conducted tests using Radeon RX 6000 series SKUs. The RX 6700 XT, RX 6800, RX 6800 XT, and RX 6900 XT were all used to compare the 21.3.2 drivers with the 21.4.1 drivers. In their testing, idle power draw dropped roughly 70% for all of the Navi 21 based cards which are the RX 6800, RX 6800 XT, and RX 6900 XT, but stayed the same for the Navi 22 based RX 6700 XT which was already low, to begin with. The Navi 22 based RX 6700 XT didn't see much of an improvement as it was already more power-efficient than the Navi 21 based cards.
