NVIDIA debuts Tegra 4i
After impressing us with the powerful Tegra 4 mobile processing chip at CES last month, NVIDIA today debuted a cost-effective variant of the chip, called Tegra 4i.
Sporting five times the power of the Tegra 3, the chip features the same compact 28nm die and the company's quad-core "4+1 battery saving core" design of the Tegra 4. With its 2.3GHz ARM-A9 CPU with 60 custom GPU cores, the 4i is designed to offer direct competition to Qualcomm's Snapdragon S800 processor. NVIDIA is touting the chip's design efficiency, and along with superior performance, the company claims it is also half the size of the Snapdragon S800.
NVIDIA is showcasing the new chip with its new reference design smartphone Pheonix. The device features a 1080p display wrapped around a super-thin 8mm body. It is unclear if NVIDIA plans to sell the device, but for now it will serve as a starting point for other brands to build their stuff upon.
