Tegra is a system on a chip (SoC) series developed by NVidia for mobile dsuch as smartphones, personal digital assistants, and mobile Internet deviceTegra integrates an ARM architecture central processing unit (CPU), graphprocessing unit (GPU) and memory controller onto one package. The serieemphasizes low power consumption and high performance for playing aud
video. The Tegra 4i (codenamed "Grey") was released on 19 February 2013
The NVIDIA Tegra 4i has one of the highest performing CPUs with a maclock speed of 2,300 MHz. It has 5 core(s), resulting in extremely efficient tasking when compared to dual core processors.

Most mobile device architectures are designed around a general purCPU.
The CPU not only underperforms but also consumes excessive powe
todays mobile use cases.
Relying on a power hungry CPU either compromises battery life to ogood performance or delivers substandard experiences.

Conclusion: Smartphones and tablets are increasingly being used as personal computin
devices.
Todays smartphonesare no longer being used for just phone calls, messagi
light Web browsing.Mobile applications for PC-class use cases such as pho
editing, word processing,multi-tabbed Web browsing,modern graphics-rich
gaming,and multi-tasking arenow availablefor mobile devices and are push
performance requirements of these devices.The quad core CPUs in NVIDTegra 4 family of mobile SoCsinclude several key enhancements thatdelive
performance for thenext generation of mobile applications.
