AMD Alleges Benchmark Cheating by Nvidia

AMD and Nvidia have been engaged in a veritable pissing match over the HQV HD video benchmark, with AMD accusing its rival of cooking its Forceware drivers in order to achieve higher scores than its product deserves. Nvidia, in turn, has accused AMD of engaging in a disinformation campaign. The issue stems from beta Vista drivers (Forceware 163.11) that Nvidia provided to reviewers testing HD-video performance with videocards based on its GeForce 8600 GTS graphics processor. AMD’s Aboubakeur Nacef ran the benchmark and took photographs that he says reveal ghosting caused by overly aggressive use of noise-reduction in Nvidia’s PureVideo HD decoder. “My feeling,” Nacef told Maximum PC, “is that Nvidia was in panic mode and needed to release something quickly.” Nvidia’s Rick Allen, countered that Nacef was “using an older driver and overly aggressive driver settings to cause the problem.” Nacef responded that Forceware 163.44 had the same problem but that he hadn’t tested version 163.69, the latest version available at press time.
