Temperature

Given the identical clock speeds of the cards, efficiency of their custom coolers is the deal breaker, and the Gigabyte HD 5670, PowerColor HD 5670 PCS+ and Sapphire HD 5670 were the best performers here, managing a core temperature of about 53 degrees Celsius. The ASUS EAH5670 and MSI R5670 were some way back, but it was the HIS Radeon HD 5670 IceQ that was most disappointing.

We have had good experience with HIS' IceQ coolers in the past, so a reading of 70 degrees Celsius was well below our expectations. Having said that, we did notice something amiss with the cooler. For one, it seemed to spinning much slower compared to the rest of the cards. And while neither GPU-Z nor the Afterburner overclocking software could show the exact fan speed, it was spinning so slowly to the point that we could not feel any warm air coming out from the exhausts. We then tried tweaking the fan speed to 100% and managed a much more respectable reading of 60 degrees Celsius. Also with noting is that despite spinning at its maximum rate, the fan was still pretty quiet.

Power Consumption

Power consumption figures of these cards were very similar to that of ATI's reference one. The only notable mentions here the slightly lower reading of the Sapphire HD 5670 at load. We also noted that the Gigabyte HD 5670 and HIS Radeon HD 5670 IceQ had marginally higher readings at idle.

Overclocking

Using the in-built ATI Overdrive utility, we found that most of the cards were limited to a maximum overclock of 850MHz at the core and 4200MHz DDR, and only the ASUS EAH5670 and PowerColor HD 5670 PCS+ were "unlocked" by their respective manufacturers so that higher clock speeds could be attained..

With the PowerColor HD 5670 PCS+, we managed to get the card to run at a respectable 950MHz at the core and 4600MHz DDR at the memory. This gave us 2689 3DMarks, a 15% bump over a standard Radeon HD 5670.

With the ASUS EAH5670, we managed to achieve 900MHz at the core and 4800MHz DDR , giving us 2729 3DMarks, the highest of the lot.
