NVIDIA's New Quad-Core 2.3GHz Tegra 4i SoC Shoots for the Middle
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.
Nvidia Debuts Tegra X1 Processor
Nvidia today announced the Tegra X1 processor, a new chip that brings the power of its Maxwell desktop architecture to mobile devices. The X1 has an octa-core 64-bit ARM processor paired with a 256-core Maxwell GPU.
Snapdragon Wear 1200 Platform Targets Simpler Wearables
Qualcomm today announced the Snapdragon Wear 1200 Platform, a new system-on-a-chip that is meant for personal fitness and tracking devices more so than smartwatches. The 1200 consumes just 79 square millimeters of space and relies on a 1.3 GHz ARM Cortex A7 processor core with an integrated Cat-M1, NB1, and eGPRS multi-mode modem.
Samsung Countersues Nvidia Over Chip Patents
Samsung has file a lawsuit against Nvidia in response to one that Nvidia filed against Samsung in September. Samsung says Nvidia is violating several of its patents pertaining to semiconductors.
Nvidia to Wind Down LTE Modem Business
Nvidia said it plans to cease chasing the LTE mobile business by the middle of 2016. Nvidia purchased a company called Icera in 2011 with the intent of integrating its own application processors with Icera's LTE modems so it could better compete with Qualcomm.
ARM Reveals DynamIQ Processor Design with AI In Mind
ARM today announced DynamIQ, a new way to manage multi-core systems that gives them the ability to scale exactly to the tasks or needs at hand. DynamIQ expands on ARM's big.LITTLE technology, which allows for paired sets of high-power and low-power processor cores to tackle specific tasks based on the computing requirements.
