NVIDIA just announced Tegra 4 at CES 2013 in Las Vegas. The processor has 72 GPU cores and is “the world’s first quad-core A15 processor, which is ARM’s new CPU architecture,” the firm explained. It also includes NVIDIA’s first 4G LTE modem.

NVIDIA took out the fastest tablet in the world today (according to its own tests), the Nexus 10, and the second was a Tegra 4 device. The company then went through and loaded 25 web pages in front of the audience at the press conference. The demo clearly showed the Tegra 4 loading web pages much, much faster. It took the Tegra 4 chip 27 seconds to load the web pages while the Nexus 10 still finished trucking along.

NVIDIA admitted that the web browser is just one example. The firm’s CEO Jen-Hsun Huang then showed us how NVIDIA’s Tegra 4 architecture reinvents the existing camera architecture in chips. Tegra 4, for example, takes advantage of all of the processors in the GPU to render two images at once (similar to HDR) but using all of the processor’s GPU power. The result is a cleaner, clearer photograph. Older architectures could take a single photo in the time it takes Tegra 4 to take a single HDR image. In a further example of a prototype, we saw live video rendering HDR imaging in real-time – today, you typically need to snap two photos to even get an HDR result.

Tegra 4 will feature a new i500 Soft Modem, which the company says it will begin sampling to partners this month.
