Yesterday, AMD released its latest Radeon Software Adrenalin (22.12.2) WHQL drivers for the Radeon RX 7900 series graphics cards.

AMD Radeon RX 7900 Drivers Carry Fixes For Higher Power Draw Usage & Other Bugs

During launch, the AMD Radeon RX 7900 series graphics cards were seen sipping in much higher power draw than the competition when idling and during normal video playback. The power draw was at times 4x higher than NVIDIA's RTX 40 series graphics card in multi-monitor & video playback.

Also, despite AMD claiming to offer a power efficiency improvement of 54% over RDNA 2, the RDNA 3-based Radeon RX 7900 series graphics cards came nowhere close to that figure. But with the new driver release, AMD is addressing some of these issues and promising to deliver further efficiency improvements in the future. Following is the changelog and the download links of the AMD Radeon Software Adrenalin 22.12.2 WHQL drivers:
