ATI Catalyst Drivers Named Most Stable by Independent Test Organization AppLabs

(Auszug aus der Pressemitteilung)

Lindon, UT – June 9, 2005 – In an independent quality and stability test by AppLabs (formerly KeyLabs),

ATI’s recently released Catalyst 5.6 Software Suite proved to be more stable than the equivalent publicly
available NVIDIA offering. An executive summary of this test is now available and the full Display Adapter
Stability Test Report issued by AppLabs and ATI Technologies Inc. will be available June 24, 2005.

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.

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.”

“In a world that is increasingly dependent on visual technology, software stability is critical to ensure the best
possible user experience,” said Ben Bar-Haim, Vice President, Software, ATI Technologies. “We built the
Catalyst software suite with the intent to deliver the most stable graphics software in the industry today, and
these tests provide further validation to that commitment.”

“AppLabs offers the industry’s most trusted and comprehensive set of testing resources,” said Mike Fahnert,
AppLabs executive vice president of client services. “The results of this test are clear: ATI’s Catalyst
Software Suite offers users of visually intensive applications the most stable 3D graphics driver available.”
