At its opening CES press conference, NVIDIA announced Tegra 4, a new mobile chipset that features 72 customer GPU cores, a quad-core Cortex-A15 CPU structure, and a 4G LTE modem. NVIDIA followed its tradition of introducing what it calls the world's fastest mobile processor, noting that the 72 NVIDIA GeForce GPU cores offer six times as much graphical power as Tegra 3. It upgraded from four A9 cores to four A15 cores, which offers a much more powerful and efficient architecture. NVIDIA claims that Tegra 4 supports web browsing that is 2.6 times faster than existing tablets, and an optional Icera i500 chipset enables LTE connectivity.

The upgrade in speed is expected considering previous iterations of mobile processors, but the enhancements enabled by the new processor are more attractive. NVIDIA introduced always-on HDR photo and video technology that can make every shot an HDR image. The advancements made in the processor enable the camera to capture photos so quickly that what usually takes 2 seconds to capture and process multiple images for dynamic range can now be done in as little as 0.2 seconds. The "Computational Photography Architecture" is able to quickly capture bright and dark areas to result in higher quality photos and videos in an instant.

The NVIDIA Tegra 4 has "battery saver core" designed for lower power consumption during less intensive activities. It also has lower backlight power consumption, which uses 45 percent less power than the Tegra 3 processor. Tegra 4 supports up to 14 hours of HD video playback on phones.
