nVidia has asked Apple to provide information about how it carried out performance tests comparing the new iPad's A5X processor with the nVidia Tegra 3.
Though Ken Brown said that nVidia was flattered to be used as a comparison, it had not been provided with any data about which benchmarks had been run or how the tests were carried out.
"We have to understand what the application was that was used. Was it one or a variety of applications? What drivers were used? There are so many issues to get into with benchmark," he told ZDNet.
nVidia will be among those buying a new iPad on launch day, Brown said, in order to better understand how Apple arrived at those conclusions, so expect to hear more about this story.
