Sapphire Ultimate Radeon HD 6670 Graphics Card Review

Power / Temps / Overclocking

As the 6900 series, GTX 500 series and no doubt future generations perform power management in a different way to older cards we have changed the way we test power and temperature levels in our reviews. For idle power we list the full system use at the wall after sitting at the desktop with no activity for 5 minutes. Load power is the highest reading we saw for the full system when testing during this review. Temperatures are taken in the same way. Noise levels are taken after a period of prolonged gaming in a scenario which applied maximum load to the GPU.

Standard
Idle Power 145w 145w
Load Power 214w 215w
Idle Temp 36°C 36°C
Load Temp 80°C 61°C

In this test we see that the Sapphire 6670 Ultimate matches the standard edition almost exactly for power use. Temperatures are higher on the new model as there is no fan assisting the heatsink but it never becomes too warm and when gaming it rarely gos above 68°C. The real selling point is the noise level though as this card is completely silent.

Overclocking
Just like the higher specification cards that Sapphire offer their lower priced alternatives fully support overclocking and to achieve higher speeds we can run Sapphires own TriXX utility. By simply moving a couple of sliders and testing for stability we can enhance the performance of the cards significantly. Shown below are the maximum overclocks we achieved on each card and the 3DMark 11 scores that each produced.
