Is the chip powering the new iPad 3 really four times faster than Nvidia's Tegra 3? Or is Apple dressing up the truth?
Apple's attempt to focus on the A5X's quad-core graphics capabilities was a sly attempt to draw attention away from the fact that the A5X is a dual-core processor (read more about the new iPad's specifications here).
If you’re talking about GPU then the Tegra 3 (as Asus pointed out in a rather sarcastic Tweet) has 12 cores. So, discounting the fact the new iPad has 1GB RAM, it’s tough to see how Apple could reach the conclusion that the A5X was four times faster than the Tegra 3. Benchmarking can be done on many different figures.
Until a new iPad is properly benchmarked Apple's claim will remain just that – a claim. Apple is famous for staying out of the stats race.
