Specifications

CPU Quad-Core, with 5th battery-saver core

Max Frequency Up to Single Core 1.5 GHz /Quad-Core 1.4 GHz

Memory Size Up to 2 GB

GPU Cores 12

Primary Camera 32 MP

Architecture

vSMP

• Low active standby state power consumption• On-demand maximum quad core performance• Transparent to the OS and applications

• Variable Symmetric Multiprocessing• Uses 4 Cortex A9 high-performance CPU cores• Fifth low power, low leakage Cortex A9 CPU core - Companion • On Demand Workload Distribution• Handled by NVIDIA’s Dynamic Voltage and Frequency Scaling (DVFS)

& CPU Hot-Plug management software

RESULT

How vSMP Helps ??

Total Power = Leakage Power + Dynamic Power

Fast Process = Optimized for high frequency operation, but higher leakage

Low Power Process = Operates at lower frequency with lower leakage

Operating System Transparent Implementation

Implements both hardware-based and low level software-based management

of the Companion core and the main quad CPU cores.

The decision to turn on and off the Companion and main cores is purely based on current

CPU workload levels

DirectTouch Architecture

NVIDIA DirectTouch improves touch responsiveness and reduces power consumption by offloading a portion of the touch processing onto the NVIDIA

Tegra 3 processor.

Benefits of NVIDIA DirectTouch Architecture

• Higher Performance: Touch controller chips are typically based on function-specific micro-controllers that have limited data processing powers. Tegra 3 are capable of operating at much higher frequencies and therefore have sufficient headroom to deliver additional processing power

• Simplified Design: The flash memory, static RAM, power regulators, and the crystal required for the touch controller are reduced or eliminated. The interface between the touch panel and NVIDIA Tegra 3 relies on an ADC chip.

• Lower Power: DirectTouch uses the Companion CPU core. The power consumption to process touch is in fact lower than that of current touch controller based solutions.

3D Gaming3D Stereo Gaming - This capability leverages NVIDIA’s award-winning NVIDIA 3D Vision® technology to automatically, and in real-time, convert OpenGL based games and apps into Stereo 3D.

Gaming Capability• Real-time physics• Real-time Dynamic Texture Generation

Quality of Graphics in originally available version of Fruit Ninja

8x higher geometry and advancedshading delivers realistic fruit images

Fuzzy shadows and low quality texture in original version of Backbreaker

Higher quality Shadows and Textures deliver more realistic game play

COMPARISON

NVIDIA PRISM Display Technology• PRISM (or Pixel Rendering Intensity and Saturation Management)• Reduces a mobile device’s backlight power• Enhancing the pixel color • Deliver the same visual quality with substantially extended battery life.
