Nvidia Tegra 4i

The Tegra 4i, Nvidia Corp.'s first mobile processor with fully integrated 4G LTE, has recently been introduced.

Previously codenamed "Project Grey," the Tegra 4i processor features 60 custom Nvidia GPU cores; a quad-core CPU based on ARM's newest and most efficient core—the Cortex-A9 r4 CPU—plus a fifth battery saver core; and a version of the Nvidia i500 LTE modem optimised for integration. The result: an extremely power efficient, compact, high-performance mobile processor that enables smartphone performance and capability previously available only in expensive super phones.

"Nvidia is delivering for the first time a single, integrated processor that powers all the major functions of a smartphone," said Phil Carmack, senior vice president of the Mobile business at Nvidia.

Tegra 4i's new 2.3GHz CPU uses the latest and greatest revision of Cortex-A9, which was defined by ARM with help from Nvidia, and is the most efficient, highest performance CPU core in its class.

Utilising the same architecture as Tegra 4's GPU, Tegra 4i features five times the number of GPU cores of Tegra 3 for high-quality, console-quality gaming experiences and full 1080p HD displays. It also integrates an optimised version of the Nvidia i500 software-defined radio modem which provides LTE capabilities, and makes networking upgradability and scalability fast and easy.

Tegra 4i mobile processor's camera capabilities include the Nvidia Chimera Computational Photography Architecture recently announced in Tegra 4. This delivers many advanced features, including the always-on high dynamic range (HDR) capabilities, first tap to track functionality and first panoramic photos with HDR.

Nvidia also introduced its reference smartphone platform code-named "Phoenix" for the Tegra 4i processor to demonstrate its unique mobile technologies. Phoenix is a blueprint that phone makers can reference in designing and building future Tegra 4i smartphones to help get them to market quicker.
