Two versions of Nvidia chip on way to mobile devices, heading into cars

Nvidia has unveiled the latest model in its mobile processor line, one which uses the same Kepler architecture as the GeForce GTX 780 Ti GPU. The Tegra K1 boasts a 192-core GPU, a major step up from the 72 and 60-core GPUs used in the Tegra 4 and Tegra 4i, with the chip producer also setting out to push the new arrival into vehicles.

Two versions of the Tegra K1 will be offered to hardware manufacturers. The first version will use a 32-bit quad-core 4-Plus-1 ARM Cortex A15 CPU clocked at 2.3GHz, while the second is a 64-bit version with a custom-designed dual "Super Core" Denver CPU based on the ARMv8 architecture. Both will provide full support for DirectX 11, CUDA, OpenGL 4.4, and tessellation, among other technologies usually seen on desktops, with Epic Games' Unreal Engine 4 said to be able to run on the chip.

The first Tegra K1 chips are expected to reach customers in devices in the first half of 2014 for the 32-bit version, and in the second half of 2014 for the 64-bit model.

Nvidia also used CES to reveal that the Tegra K1 will be incorporated into computer systems used in cars. The Tegra K1 VCM (Vehicle Computing Module) will help power various driver assistance systems (DAS), including camera-based pedestrian detection, blind-spot monitoring, and street sign recognition, as well as monitoring the driver's alertness. The extra processing power can be extended to the dashboard, allowing for extreme customizations of digital instrument clusters, as well as powering in-car entertainment systems.
