Nvidia has outed its
next-gen Tegra 4 mobile CPU at CES. As expected, the chip packs 72 GPU cores, offering a 6x bump on the Tegra
3′s graphics processing performance — to make the most of higher resolution
displays — along with the first quad-core ARM Cortex-A15, to boost web browsing
speed by 2.6x and deliver improved app performance. Also on board: LTE support.
Nvidia is talking up the computation photography capabilities of the Tegra 4,
with automatic support for HDR photos and video, and also its power efficiency
— claiming it consumes up to 45 per cent less power than the Tegra 3 in “common
use cases”, thanks to features such as a battery saver core for low power
during standard use. The Tegra 4 supports up to 14 hours of HD video playback
on phones.
Also today at CES,
Nvidia has launched an open gaming handheld — dubbed ‘Project Shield‘ — powered
by the new Tegra 4 chip. The handheld can download Android games from Google
Play and Nvidia’s TegraZone game store, and also wirelessly stream Windows PC STEAM
games — provided you have a PC powered by Nvidia GeForce GTX GPUs elsewhere in
the home. The use-case here is presumably if you want to flop out on the sofa
to play to play PC games, rather than sitting at your desk. The handheld
hardware includes a 5-inch, 1280×720 HD retinal multitouch display, hinged atop
the controller.
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. 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.
