Nvidia introduces Tegra 4, here’s what you should know

The new Tegra 4 System on a Chip was just unveiled in Las Vegas, and we have the full rundown here. Along with the new SoC, Nvidia’s boss Jen-Hsun Huang also touted the Icera i500 baseband chip, a reprogrammable LTE chip that will run Tegra 4 devices run on a multitude of LTE networks, and the Shield, Nvidia’s first gaming handheld.



The biggest news of the night is, however, Tegra 4, a name that we are likely to hear a lot in the next year or so. Although Nvidia didn’t supply the full spec sheet for the new Tegra 4, we compiled enough information to make a rather complete picture of the powerful new SoC.
