Temperatures and Power Consumption

TEMPERATURES

To test temperatures, we fire up FurMark and let it run for awhile until the temperatures level out. FurMark pushes GPU thermal loads extremely high, and can be considered a worst-case scenario.

Below are the FurMark "worst case" results:

Temperatures

The original 5800 cards were notoriously warm chips, but Sapphire overhauled the coolers on these Xtreme cards and it shows. As we often see from Sapphire, their heatsink designs are top notch and are doing an excellent job at keeping the tempeatures under control at full load. The idle results aren’t quite as impressive, but the Delta is very minimal when we crank up the juice, far better than the Nvidia cards. Most notably, the 5850 Xtreme was a close second to the 6870 in terms of graphics performance but we see that it’s 15°C cooler. Outstanding.

POWER CONSUMPTION

We create a baseline power draw without a graphics card installed. After a graphics card is installed, we let the system sit idle in Window for 10 minutes and then run FurMark for maximum power draw. The difference gives us the power consumption for the card. The results below are for the graphics card only.

Power Consumption

Again Sapphire has done a great job with these Xtreme cards, as they’re sufficiently frugal to put them on equal terms against the 6800 cards. And compared to the Nvidia competition, the Sapphire cards show considerably better performance-per-watt results.
