Nvidia Tegra 4i LTE on-chip tech introduced
Nvidia has announced its first fully integrated 4G LTE mobile processor, the NVIDIA Tegra 4i, which is “significantly faster yet half the size of its nearest competitor”, the company claims.
The Tegra 4i processor features 60 custom NVIDIA GPU cores; a quad-core 2.3GHz CPU based on ARM’s newest and most efficient core – the R4 Cortex-A9 CPU – plus a fifth battery saver core; and a version of the NVIDIA i500 LTE modem optimized for integration. The Tegra 4i was jointly designed by NVIDIA and ARM.
The 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 world’s first always-on high dynamic range (HDR) capabilities, first tap to track functionality, and first panoramic photos with HDR,” claims Nvidia.
NVIDIA also introduced its reference smartphone platform code-named “Phoenix” for the Tegra 4i processor. Phoenix is a blueprint that phone makers can reference in designing and building future Tegra 4i smartphones.
