Tegra - Computer Definition
A system-on-chip (SoC) family from NVIDIA for smartphones, tablets and other portable devices. Introduced in 2008 and based on ARM CPUs (ARMv7), the Tegra chip includes a low-power NVIDIA GeForce GPU, along with audio, video and camera support. Tegra 2, 3 and 4 Tegra 2 models use dual-core CPUs, and Tegra 3, introduced in 2011, was the first quad-core SoC for smartphones. Tegra 4 (2013) added a low-power core that automatically handles background tasks and is not addressable by the OS. Tegra 4 graphics are considerably faster than Tegra 3. Tegra K1 (2014) Designed to allow video games that normally require a PC or video game console to run in low-power mobile devices, the Tegra K1 employs a modified version of the Kepler GPU used in PC graphics. The K1 chip is available in 32-bit and 64-bit models. See mobile platform and SoC.
