Nvidia Tegra 4
Nvidia's fourth-generation mobile processor was introduced, once again, in early January at the Consumer Electronics Show, and like previous releases, the Tegra 4 arrived with some notable improvements. The mobile system-on-a-chip (SoC) boasts a quad-core ARM Cortex-A15 processor running at 1.9 GHz, plus a second-generation power-saving core to boost battery life. Nvidia's Variable SMP architecture allows the SoC to use the single battery-saving core for low-power tasks while shifting heavier tasks to the four primary cores for maximum performance. The Tegra 4 also features 72 graphics cores that process graphics six times faster than the Tegra 3 platform, according to Nvidia, and can support Ultra HD resolutions of up to 3,200-x-2,000.
