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.

That's a rather bold statement given we don't know what kind of bottlenecks the system might have. What if they did not double the graphic ram bandwidth, what if the cpu can't feed the quad core gpu fast enough.
Now I'm not saying it's not 4x faster, just we can't even guess till it's released.

The post to which you are replying started with someone accusing us of cherry picking by looking at only the GPU performance benchmarks rather than CPU - the answer to which was that the claim was specifically about GPU performance, and not CPU performance. He didn't object to the benchmarked truth that even the old iPad 2 is faster graphically than Tegra 3.
Your claim is essentially that we have no proof until we run benchmarks, which is obvious, but that doesn't mean we can't make educated guesses based on the performance of the previous generation taking into account what was upgraded.
You would, I feel, need more evidence if you were claiming that this logical deduction was incorrect.
