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.

You guys are getting way too worked up over this.
1. Apple doesn't have to prove this. Why would they have to? That's how marketing works.
2. Even if there is one benchmark under one specific circumstance that shows the GPU to be 4 times faster than the Tegra 3 the statement would be valid. They could even do an external display that isn't "retina" and it wouldn't technically be cheating. Again, that's how marketing works.
3. The MP2 is quite a bit faster in select benchmarks than the Tegra 3. It's not a stretch to believe the MP4, with twice the theoretical computing power, could show 4 times the power in a carefully selected benchmark. I know it doesn't scale that way in real life but synthetic benchmarks aren't real life!
4. Pushing 4 times the pixels doesn't mean 1/4 of the performance. Anyone who has ever ramped up the resolution on their video game and then tested the FPS would know this. As you scale up in resolution the frames drop but it is not linear. I would never expect increasing my resolution 50% to lead to a 50% drop in FPS. That just wouldn't happen.

4th point makes sense!!
Still I do not know why apple did not double the cores on the CPU! But i do think they must have done their analysis before choosing this design.
I really do not think too highly about windows tablets or androids. Ipads and Iphones are cool because of the large database of applications!
