Mid-Range AMD Graphics Card Round-Up (HIS 7770 GHz / HIS 7850 / Sapphire 7850)

We measured the power consumption of our entire test system at the wall while loading the graphics card using FurMark. We also measured the power consumption with the system idling at the Windows desktop. As these are gaming graphics cards, we also decided to measure the power consumption while playing Battlefield 3.

As expected, HIS' 7770 GHz Edition IceQ X Turbo graphics card shows the lowest power consumption numbers. With the 7770 installed, our system's gaming power consumption didn't even surpass the 200W mark. Low power consumption levels such as those exhibited by HIS' 7770 GHz Edition IceQ X Turbo graphics card make it a great option for gaming HTPCs.

HIS' enhanced power delivery components clearly do their job by providing power more efficiently than the reference configuration used on Sapphire's card. The increased power consumption by Sapphire's 7850 Dual-X is also related to its additional fan.
