LG Electronics has confirmed it will be using a dual-core processor manufacturred by Nvidia for its line of Optimus smartphones later this year. The Wall Street Journal notes that this is a coup for Nvidia, which has been pushing to enter the smartphone market with its Tegra chip and expand beyond its traditional business of providing graphics chips for PCs. To date, the most notable phone to use Tegra was Microsoft’s failed Kin youth-centric device.
