In a (somewhat simulated) head to head test between a Nexus 10 tablet and and a Tegra 4 mystery machine, the latter loaded 25 webpages in only 27 seconds, with the older chip taking 50. Not many of us will be loading up 25 webpages simultaneously, but Nvidia is hammering beefed up browser performance here—as well as topping the iPad 4's A6X processor across the board. Nvidia says it's simply the fastest mobile processor in the world. Nvidia says.
The Tegra 4 will also have supercharged HDR photo rendering, Nvidia says, beating out the iPhone 5's abilities with better capture speeds thanks to all of those aforementioned cores working at once. In actual life terms, Nvidia says it'll be the difference between two seconds of rendering on the iPhone and 0.2 seconds on a Tegra 4-powered mobile camera.
