(Telecompaper) Nvidia has announced the Tegra 4i 4G LTE processor, described as half the size and significantly faster than its nearest competitor. Until now codenamed "Project Grey," the Tegra 4i features 60 custom GPU cores; a quad-core CPU based on ARM's R4 Cortex-A9 CPU, a fifth battery saver core, and a version of the Nvidia i500 LTE modem. The Tegra 4i's new 2.3 GHz CPU was jointly designed by Nvidia and ARM. Nvidia said its processor enables smartphone performance and capability previously available only in expensive super phones. Nvidia introduced its "Phoenix" reference smartphone platform to demonstrate the Tegra 4i processor. Phoenix is a blueprint that phone makers can reference in designing and building future Tegra 4i smartphones.
