Graphics card round up March 2013

The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 20c – a comfortable environment for the majority of people reading this.

Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.

The Sapphire cards rate very highly in regards to cooler efficiency, taking the top positions in the chart, next to the XFX H7770 Core which claims the top position. The most remarkable result is the powerful Sapphire HD7950 Vapor X, which hits only 57c when gaming. While the card is closely matched against the Zotac GTX670 in performance, the Sapphire cooler is much better.
