Average (Gaming): Metro: Last Light at 1920x1080 because it is representative of a typical gaming power draw. This codec should have GPU-accelerated decoding on every modern GPU, so it tests not only GPU power management, but also efficiency of the video decoding hardware. Media Playback: We use VLC Media Player to watch a 4K 30 FPS video that's encoded with H.264 AVC at 64 Mbps bitrate, making it similar enough to many streaming services as well, without adding a dependency on internet bandwidth. Our test represents the usage model of many productivity users who have one big screen and a small monitor on the side. When using two identical monitors with the same timings and resolution, power consumption will be lower. The card is left to warm up in idle mode until power draw is stable. 
Rtx 3080 power consumption drivers#
Windows 10 is sitting at the desktop (1920x10x1024) with all windows closed and drivers installed.
Multi-monitor: Two monitors are connected to the tested card, and both use different display timings. Idle: Windows 10 sitting at the desktop (1920x1080) with all windows closed and drivers installed. Our results are based on the following tests: We use Metro: Last Light as a standard test for typical 3D gaming usage because it offers the following: very high power draw high repeatability is supported on all cards drivers are actively tested and optimized for it supports all multi-GPU configurations test runs in a relatively short time and renders a non-static scene with variable complexity. Again, these values only reflect the card's power consumption as measured at its DC inputs, not that of the whole system. 
A Keithley Integra 2700 digital multimeter with 6.5-digit resolution is used for all measurements. Lower heat output also helps improve cost because smaller, cheaper thermal solutions can be used.įor this test, we measure power consumption of only the graphics card via the PCI-Express power connector(s) and PCI-Express bus slot. It is also the foundation for low noise levels because any power consumed will turn into heat that has to be moved away from the GPU by its thermal solution. Improving power efficiency of the GPU architecture has been the key to success for current-generation GPUs.
