Before bringing this article to a close, we'd like to cover a few final data points--namely power consumption and noise. Throughout all of our benchmarking and testing, we monitored how much power our test system was consuming using a power meter. Our goal was to give you all an idea as to how much power each configuration used while idling and while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the graphics cards alone.

Total System Power Consumption

Tested at the Outlet

Considering the kind of performance offered by the dual-GPU Radeon HD 6990, it's no surprise the card uses a lot of power, relatively speaking. When running at its stock clocks, our test system pulled 484 watts from the outlet with the Radeon HD 6990 installed, which was somewhat lower than the GeForce GTX 590. With the Radeon HD 6990 running in AUSUM mode though, it used the most juice, coming in at 529 watts.

With that much power being consumed, the Radeon HD 6990 has a good amount of heat to dissipate, and as such the card can be fairly loud when running under a sustained load. If you're thinking of a 6990, be warned that the card does generate a good amount of noise when being pushed. It's quiet at idle, but under load you're definitely going to hear it above your other system components.

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
