Nvidia unveils Tegra 4, ‘world’s fastest mobile processor’
Published on January 8th, 2013 | by sylv3rblade0
Nvidia has officially unveiled the successor to it’s marginally successful Tegra 3 SoC, the Tegra 4.
Like it’s predecessor, the Tegra 4 still uses a 4-PLUS-1 configuration. While it does offer the same setup, the Tegra 4 now uses four Cortex-A15 CPU for it’s compute needs and 72 GPU cores for it’s pixel processing duties. It also benefits from a new 28nm which helps bring the down power envelope of the new Tegra while providing more number crunching capabilities, something that crippled the Tegra 3 as devices that incorporated it showed poor battery life compared to what the competition offered.
Nvidia’s press release is available below:
LAS VEGAS, NV–(Marketwire – Jan 7, 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
Nvidia expects the Tegra 4 to appear not just on tablets but on smartphones and notebooks as well. Pricing and availability for the new Tegra Soc is not yet released however but we can expect the first devices to hit late this year.
