HIS Radeon HD 5750 iCooler IV Video Card Benchmarking

Power Consumption

To test the power consumption of the Sapphire Vapor X 5750 the test bench was plugged into a P3 Kill-A-Watt. Idle power consumption was taken 15 minutes after logging into Windows 7 with no other programs running.  The load tests were done running FurMark 1.70 with a resolution of 1024×768. This brought the load on the GPUs to 100%.

Sapphire Vapor-X power consumption

One of the reasons the idle power consumption is so low is due to the fact that the card throttles back dramatically.  The GPU core clock drops from 700MHz all the way to 157MHz and the GPU memory clock under load is 1150MHz and at idle is only 300MHz.


Benchmark Results: Of all the cards in my possession the HIS Radeon HD5750 idles below them all.  The only card that has a lower load value was the 9600GSO, which has nowhere near the same performance level.
