After unveiling the Tegra 4, the company's next generation mobile processor at CES 2013 in Las Vegas, NVIDIA has now announced the Tegra 4i, its first fully integrated 4G LTE mobile processor, which as per the company is significantly faster yet half the size of its nearest competitor.

The Tegra 4i processor, which was codenamed 'Project Grey,' features 60 custom NVIDIA GPU cores, a quad-core CPU based on ARM's R4 Cortex-A9 CPU, in addition to a fifth battery saver core, along with a version of the NVIDIA i500 LTE modem. The Tegra 4i processor utilises the same architecture as Tegra 4's GPU, and features five times the number of GPU cores of Tegra 3 for delivering a high-quality, console-quality gaming experiences and full 1080p HD displays, which are now becoming the most touted feature when it comes to flagship smartphones.

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

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

"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 phones will provide amazing computing power, world-class phone capabilities, and exceptionally long battery life."

The Tegra 4i's new 2.3 GHz CPU was jointly designed by NVIDIA and ARM.

"Tegra 4i is the very latest SoC solution based on the ARM Cortex-A9 processor and demonstrates the ability of ARM and our partners to continue to push the performance of technology and create exciting user experiences," said Tom Cronk, executive vice president and general manager, processor division, ARM. "ARM and NVIDIA worked closely to further optimize the Cortex-A9 processor to drive performance and efficiency in areas such as streaming and responsiveness. This is an example of the collaboration and innovation that enables ARM technology-based solutions to be market drivers through multiple generations of SoC solutions."

The company will be demonstarting the Tegra 4i mobile processor at the Mobile World Congress in Barcelona.
