The LG Optimus 4X HD is LG’s top of the line device and was announced a couple of days ago at Mobile World Congress. It’s very much a follow up to last year’s Optimus 2X, and ups then umber of CPU cores from 2 to 4 thanks to the Tegra 3 chipset. It has an impressive 4.7″ 720p screen and 16GB of inbuilt storage.
In this hands-on demo, we get to see a look at how the 4-Plus-1 setup of the Tegra 3 works in action with an on-screen CPU meter that changes based on number of cores used. Obviously, when the phone is idle, only one core is active, but when you launch something like the camera, all four cores are utilized.
