As we have said, the ASUS Matrix GTX580 Platinum is overclocked, but by a relatively modest amount. Hence, users will generally see only a slight bump in their scores, which brought its performance close to that of the older, dual-core Radeon HD 5970. In most of the actual games tested, the ASUS was mostly neck to neck with the Sparkle Calibre, which runs at 810MHz for the core and 4032MHz DDR for the memory.
Where the ASUS excelled was in our temperature testing, as we found its 58 degrees Celsius reading to be 11 degrees less than the Sparkle Calibre, which has a triple-fan cooler. Compared to the 80 degrees that we recorded on the reference GTX 580, the ASUS' DirectCU II cooler was doing a great job. The ASUS also showed slightly lower idle and peak power draws than the other two GTX 580 cards here.
Finally, we tested the overclocking allowance of the ASUS. Bear in mind that we just went with the usual air-cooled method and simply pushed the clocks up using the GPU Tweak utility. We found that the ASUS Matrix reached higher core and memory clocks compared to the Sparkle. When we turned the fan on the Matrix to its extremely noisy, 100% speed, we could squeeze out a marginally higher result. However, we doubt that users will find the extra clock speeds worth the din created.
