NVIDIA has unveiled its Tegra 4i, its first fully integrated 4G LTE mobile processor.

The manufacturer said the 2.3 GHz processor performed all the major functions of a smartphone and incorporated an optimised version of its i500 LTE radio modem, which provided LTE capabilities.

It had 60 GPU cores, a quad-core CPU based on the R4 Cortex-A9 CPU, ARM’s newest core, and a fifty battery saver core, the manufacturer said.

NVIDIA and ARM had worked to further optimise the Cortex-A9 processor, focussing on performance and efficiency in streaming and responsiveness, among other areas, ARM processor division executive vice president Tom Cronk said.

“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.”

It was the latest System on a Chip based on the Cortex A9 processor, Mr Cronk said.

The processor included the Chimera computational photography architecture, which included always-on high dynamic range (HDR) capabilities, and will be making an appearance at Mobile World Congress.
