During yesterday’s Apple event, senior VP of worldwide marketing Phil Schiller took the stage to tout the power of the new A5X processor that inhabits the innards of the latest iPad.

Schiller stood in front of a chart showing the relative graphics performance of the NVIDIA Tegra 3, the Apple A5 (2x the performance of the Tegra 3), and the new A5X (4x the performance). Not surprisingly, NVIDIA is now taking exception to Apple’s claims about the performance of the A5X.

NVIDIA spokesman Ken Brown was quoted on ZDNet as saying that “We don’t have the benchmark information. 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.”

As a result, NVIDIA is planning to get a new iPad once they hit the streets on March 16 to do some comparisons. Says Brown, “At some point it will become more clear what the performance really is. For now, Apple has a really generic statement.”

To quote our very own Chris Rawson, “Prediction: Once NVIDIA runs A5X benchmarks and finds out it trounces the Tegra 3, we hear nothing more from them about it.”
