See the Nvidia Tegra 4 (and 4i) in action
BARCELONA, Spain--Nvidia's latest mobile processor, the Tegra 4, and its little brother, the Tegra 4i, will soon be turning up in all manner of smartphones and tablets. I went hands-on with some of Nvidia's reference devices at Mobile World Congress and found the new silicon to deliver some impressive results.
Like the Tegra 3 chip before it, the Tegra 4 is a quad-core processor with a fifth power-saving core for less intense tasks. Based on ARM's latest Cortex A-15 platform, it boasts a faster clock speed and a whopping 72 GPU cores -- that's six times the graphics grunt offered by the Tegra 3 chips.
There aren't currently any devices running the new chips, but Nvidia had some reference tablets to show it off. I booted up the Geekbench 2 benchmark test on one of the 1080p slates and was quickly given the superb score of 4,166. By comparison, Google's Nexus 7, running the Tegra 3 chip, achieved 1,536 -- and that's far from sluggish.
I was shown the game Zombie Driver, too. It's been optimized for the Tegra 4 chip, making full use of dynamic, real-time shadows and high-definition graphics on the 1080p display. It seemed to run extremely smoothly with high frame rates that will no doubt keep casual gamers satisfied.
