Tegra 4 ▼
Tegra 4 is an NVIDIA mobile system on a chip (SoC) which has been officially launched on January 6 at CES 2013. Tegra 4 contains four general processor blocks based on the ARM Cortex A15 design. It also features a “companion core” which is designed to handle low-intensity tasks while using as little power as possible. When the companion core is “ON”, the four faster cores are turned OFF for maximum power-savings. Tegra 4 also features 72 graphics cores, and assuming that they are comparable to the Tegra 3 graphics cores, it would translate into a 6X graphics performance boost.
