NVIDIA shows off the new Tegra 4 processor
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.
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.

NVIDIA Introduces World's Fastest Mobile Processor
Sunday, January 6, 2013
CES -- NVIDIA today introduced NVIDIA® Tegra® 4, the world's fastest mobile processor, with record-setting performance and battery life to flawlessly power smartphones and tablets, gaming devices, auto infotainment and navigation systems, and PCs.
Tegra 4 offers exceptional graphics processing, with lightning-fast web browsing, stunning visuals and new camera capabilities through computational photography.
Previously codenamed "Wayne," Tegra 4 features 72 custom NVIDIA GeForce™ GPU cores -- or six times the GPU horsepower of Tegra 3 -- which deliver more realistic gaming experiences and higher resolution displays. It includes the first quad-core application of ARM's most advanced CPU core, the Cortex-A15, which delivers 2.6x faster web browsing and breakthrough performance for apps.
Tegra 4 also enables worldwide 4G LTE voice and data support through an optional chipset, the fifth-generation NVIDIA Icera® i500 processor. More efficient and 40 percent the size of conventional modems, i500 delivers four times the processing capability of its predecessor.
"Tegra 4 provides enormous processing power and efficiency to power smartphones and tablets, gaming devices, auto systems and PCs," said Phil Carmack, senior vice president of the Tegra business at NVIDIA. "Its new capabilities, particularly in the area of computational photography, will help improve a whole range of existing products and lead to the creation of exciting new ones."
Computational Photography Capability
Among the Tegra 4 processor's breakthroughs is its Computational Photography Architecture, which automatically delivers high dynamic range (HDR) photos and video by fusing together the processing power of the GPU, CPU and the camera's image-signal processor.
Its HDR capability captures images, including those taken with a flash, the way they are seen by the human eye -- with detail in both bright and dark areas.
Unprecedented Power Efficiency
Designed for maximum energy efficiency, Tegra 4 includes a second-generation battery saver core for low power during standard use, and PRISM 2 Display technology to reduce backlight power while delivering superior visuals.
Tegra 4 consumes up to 45 percent less power than its predecessor, Tegra 3, in common use cases. And it enables up to 14 hours of HD video playback on phones.
Tegra 4 Key Features
- GeForce GPU with 72 custom cores
- Quad-core ARM Cortex-A15 CPU, plus a 2nd Generation Battery Saver Core
- Computational Photography Architecture
- LTE capability with optional Icera i500 chipset
- 4K ultra-high-def video support
