NVIDIA shows off the new Tegra 4 processor

NVIDIA shows off the new Tegra 4 processor
With CES 2013 about to kick-off in Las Vegas, the folks at NVIDIA started things off with a bang showcasing their new Tegra 4 SoC for mobile devices.

As some information was leaked last month about the Tegra 4, the official word from NVIDIA is that the new SoC will feature an amazing 72 GeForce GPU cores with 4K video support, which is about 6 times the visual processing power of the current Tegra 3. It will also feature a quad-core ARM Cortex A15 processor and a second generation battery saver core.

Unlike the 40nm manufacturing process on the Tegra 3, the Tegra 4 will be at 28nm, and support PRISM 2 technology for less power used by the backlight. All of this will allow for 45% better power management and lower heat compared to the Tegra 3.

NVIDIA showed some of the speed differences of the Tegra 4 next to current devices, as a Tegra 4 device can load in 27 seconds while a Nexus 10 takes 50 seconds to load. The Tegra 4 also supports a new NVIDIA Computational Photography Architecture to help to take better pictures by integrating different functions. This not only lessens the time to capture an image by 10X, but allows faster HDR images and videos, as well as HDR panorama, strobe motion, 3D reconstruction, and subject tracking.

As an option, device manufactures can add the NVIDIA i500 Soft Modem, which is a programmable LTE baseband chip that can accompany the Tegra 4. It is said to support up to 1.4 trillion operations per second and is 40% smaller than traditional baseband chips.

There is still no word yet on which new devices will feature the Tegra 4, but we'll be looking for them while at CES!
