NVIDIA Tells Apple to "Prove It" on A5X Performance Claims

Benchmarks or GTFO!
Yesterday when Apple
the new iPad, the crew from Cupertino took some time to brag about its new A5X processor in comparison to NVIDIA’s Tegra 3. Apple certainly isn't widely known for offering up benchmarks on its own, so we'll likely have to wait until iPads land in the hands of reviewers and geeks around the web.
Apple used the iPad unveiling to boast that the A5X chip inside the new iPad is two times faster than A5, and four times more powerful in graphics performance than the Tegra 3.
NVIDIA isn't buying those claims without proof. The graphics company wants to know how Apple came by that number. Ken Brown, a spokesman for NVIDIA, stated, "[It was] certainly flattering " for Apple to compare its newest chip to their part.
Brown continued, “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.”
Anyone that follows tech knows benchmarks are often handpicked to favor one particular brand over another when it comes to claims such as these. So it should be interesting to see if the new iPad’s performance lives up to the claims.

Please see this link for a more balanced view on reality:
The lead for PoverVR SGX543MP2 over Tegra 3 varies from 10% to 100%. On average, I would say that MP2 is around 1/3 faster, far away from the 2x claim.

Its also a comparison between platforms (i.e Android vs iOS) using pre release drivers on a pre release tablet.
Seems like the MP2 beats out the Tegra 3 either way, but the comparison still seems a little flawed.
Had Apple implemented the Tegra 3 themselves and used it in the iPad, do you really think the performance gap would have been as large?
Tegra 3 also most likely still beats out the A5x in raw CPU performance, as it still seems to be the same dual core A9 based chip found in the A5.(perhaps at a different clockspeed)
