In June 2005, ATI commissioned AppLabs, a leading provider of quality assurance and testing, to conduct the test, pitting ATI's Radeon® display adaptors against comparable NVIDIA GeForce products. The objective of the test was to perform advanced software stress testing of the Radeon product line against the GeForce product line. AppLabs used publicly available test applications extracted from Microsoft's latest Windows Hardware Quality Lab test suite 5.3 to conduct the study in its Lindon, Utah facility. Testing was conducted on a variety of graphics adaptors from each of the two manufacturers, and included the repeated execution of a multitude of test cases (for more than 500 times on each card) to mimic a typical, long term, real-world PC usability scenario.The full test report is scheduled to be released June 24.
In this series of independent trials, ATI consistently earned higher stability rankings, scoring as high as 8.6 percent above NVIDIA. The AppLabs report concluded: "Based on the results of these software stress tests, the stability of the ATI Catalyst software exceeded that of their NVIDIA counterpart."
