NVIDIA announces Tegra 4, 72-core GPU, quad-core CPU (Cortex-A15), 4G LTE modem


Tonight NVIDIA finally revealed their Tegra 4 chip, which they claim is the world’s fastest mobile processor. In line with earlier leaks, Tegra 4 offers the world’s first mobile chip with quad-core Cortex-A15 CPUs. This latest generation of ARM’s CPU core has appeared in new devices like the Samsung Nexus 10, but NVIDIA claims their design is up to 2x faster than Samsung’s Exynos 5 Dual chip.

“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.”

Highlights of Tegra 4 include:

  • 72 custom NVIDIA GeForce GPU cores - six times the GPU horsepower of Tegra 3 for more realistic gaming experiences and higher resolution displays. Enjoy a variety of unique mobile device innovations in media, gaming, and web–including WebGL and HTML5.
  • The first quad-core ARM Cortex-A15 CPU- for 2.6x faster web browsing and breakthrough performance for apps. Tegra 4 harnesses ARM’s most advanced CPU cores ever, plus a second-generation battery saver core, to deliver record levels of performance and battery life. This Variable SMP architecture invented by NVIDIA enables four performance cores to be used for max burst, when needed, with each core independently and automatically enabled and disabled based on workload. The single battery-saver core handles low-power tasks like active standby, music and video playback and is fully transparent to the OS and applications.
  • Worldwide 4G LTE voice and data support - through an optional chipset, the NVIDIA Icera i500 modem processor Tegra 4 leverages proven Icera technology in an optional chipset to deliver exceptional mobile communication capability.
  • New computational photography capabilities — dramatically enhancing mobile imaging for HDR photos and video. This new mobile architecture fuses together the processing power of the CPU, GPU and ISP to allow device makers to dramatically enhance mobile imaging. This enables the first Always-on HDR camera with features like live HDR preview, instant HDR photos, HDR video, HDR burst and HDR Flash.
  • Superb power efficiency, with a second-generation battery saver core and PRISM 2 display technology — giving up to 14 hours of HD video playback on smartphones.
