It's CES 2013, and NVIDIA has just kicked it off in a way that only NVIDIA can: by announcing the world's first quad-core A15 CPU – the Tegra 4. It uses the same 4-PLUS-1 setup as the Tegra 3, which has the fifth "battery saving" core, but supercharges it in basically every way imaginable. For starters, it features 72 GPU cores. That's a lot of cores.
Past that, it's the first Tegra processor to have an onboard 4G LTE modem (finally!).
