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 same timings and resolution, power consumption will be lower. Card left to warm up in idle mode until power draw was stable. Windows 7 Aero sitting at the desktop (1920x1080+1280x1024) with all windows closed and drivers installed. Multi-monitor: Two monitors connected to the tested card, both using different display timings.

Idle: Windows 7 Aero 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 representing typical 3D gaming usage because it offers the following: very high power draw high repeatability is a current game that 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, the values here 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. An optimized fan-profile is also one of the few things board vendors can create to impress with reference designs where they are prohibited from making changes to the thermal solution or components on the card.įor this test, we measure the power consumption of only the graphics card via the PCI-Express power connector(s) and PCI-Express bus slot. Cooling modern video cards is becoming more and more difficult, especially with users asking for a quiet cooling solution, which is why engineers are now paying much more attention to the power consumption of new graphics card designs.
