When NVIDIA unveiled Tegra 4 back at CES we we really needed to see benchmarks, some more ata to help show the difference between Tegra 4 devices and whatever's currently on the market. Over at the Mobile World Congress Nvidia has reference tablets set up expressly for the purpose of running tests. The guys from ngadget had a test run, check it after the break to see how it fared.

SunSpider: lower scores are better
As you can see, those numbers are pretty impressive, particularly stunning was that SunSpider result says engadget:
Which should give you a strong idea of what you can expect in terms of web browsing performance. In short, the tablet chewed through all that code in just 499ms (keep in mind that lower numbers are better in this particular test). To give you some perspective, the iPad 4 scores an average of 865ms in the test. So if you enjoy the web browsing experience on your iPad, you're going to be pretty pleased what NVIDIA has to offer here. Put differently, when we ran SunSpider on a laptop, the desktop version of Chrome achieved a score of 188.8ms -- we're used to seeing a much bigger gap between desktop and mobile browsers.
In addition to letting us benchmark our hearts out, NVIDIA showed us a demo of that same reference tablet hooked up to the same sort of power meter OEMs use to measure power consumption. As you can see in the video below, we've got a 1080p video running, with the power rating hovering around 950 milliwatts, compared to 1.2 watts on some other 1080p devices. The result, says Matt Wuebbling, director of Tegra product marketing, is an extra two hours of battery life compared to the competition. Of course, we can't take his word for it -- we'll just have to wait until we get our first Tegra 4 phone in to review. If nothing else, though, that clip below gives you another chance to see how Tegra 4 handles full HD movies. Take 'er away, and stay tuned for some proper reviews -- hopefully in the not-too-distant future.
