NVIDIA today announced the Tegra 4i, a new system-on-a-chip coupling a processor and modem for mid-range smartphones. The Tegra 4i uses the four-plus-one configuration that NVIDIA prefers. It has a 2.3GHz quad-core ARM R4 Cortex A9 cluster for raw computing power, plus a fifth low-power core to help manage battery life. NVIDIA says the 4i can handle gaming on full 1080p HD displays, as well as always-on HDR photography, among many other multimedia functions. The 4i also includes 60 GPU cores and an integrated i500 LTE 4G modem. The i500 has been optimized for the 4i and supports software-defined radios for better global LTE compatibility. NVIDIA claims the 4i SoC is half the size of Qualcomm's Snapdragon 800, making it ideal for compact, low-cost devices. Along with the new processor, NVIDIA announced a reference smartphone called the Phoenix with the 4i built-in so phone makers can see how best to integrate the 4i into their own devices.
