Power Consumption

In this section we want to show you how much power is needed by the complete systems (without the monitor) equipped with the tested graphics cards. We measure the power consumption by means of the Corsair AX1200i power supply. The result is the sum total of the consumption of each system component. The PSU’s efficiency doesn’t affect it.

There are two test modes: idle and high load (FurMark 1.9.2 running in Burn mode in a 1280x720 window). We use FurMark for the high-load mode since, like most professional applications, it is based on OpenGL and is a heavy load indeed.

Comparing professional cards from the same price categories, the Quadro series looks far more economical. The Quadro K5000 configuration needs almost 50 watts less than its FirePro W8000 counterpart. The Quadro K4000 consumes 34 watts less than the FirePro W7000. Nvidia puts an emphasis on this fact, counting the energy efficiency of its Quadro series among its advantages. Well, it might be expected as the GPUs of the Quadro cards do not have maximum specs and the cards themselves don’t have two additional power connectors.

The FirePro series, on its part, is close to gaming cards in its design. That’s why their heat dissipation and power consumption are comparable to those of the Radeon HD series, which means that AMD-based workstations are going to be noisier and hotter than their Nvidia-based counterparts.
