Methodology

For graphics card testing, here at XSReviews our aim is to provide a set of clean, reliable benchmarks. For each test, the test was repeated three times and then an average taken or where results were inconsistent, tests were continued until two concordant results were reached.

The benchmarks consist of a mixture of games and synthetic benchmarks; games testing is carried out through a specifically designed benchmark suite for that particular title or by using a time demo and the utility FRAPS to record the frame rates. The following software was used in the testing of the graphics cards:

  • 3Dmark 11
  • 3Dmark Vantage
  • 3Dmark 06
  • Furmark – for temperature testing
  • Unique Heaven
  • DIRT 3
  • Crysis Warhead
 

Overclocking and Thermals

The Sapphire 6850 Vapour-X was a joy to overclock. I used Sapphire Trixx to overclock the card and tested stability using Furmark.

After around 20 minutes of tweaking, I found that 1060MHz on the core, with 1.25V was the highest stable clock I could achieve.

The Vapour-X cooler did a great job. Running at stock speeds the GPU sat at 38C at idle and 68C under load. While overclocked the GPU only hit 74C which is well within the thermal limits of the core. Throughout the tests the fan stayed very quiet and only became slightly audible under overclocked load.
