Android Central @ CES

Today at CES 2013, NVIDIA announces the Tegra 4 processor, which features 72 GPU cores, 4 A15 CPU cores, and a 4G LTE processor. What does that mean in practical terms? 27 seconds to load 25 unique web pages (versus 50 seconds on a Nexus 10). NVIDIA claims browsing is even faster at browsing the web than the iPad 4, Droid DNA, and Kindle Fire HD.

Another utility is in photography. NVIDIA showed off the Tegra 4 processor handling HDR photography better than the iPhone 5, which takes two seconds to process (compared to the Tegra 4's 0.2 seconds). They demoed on stage a prototype Windows tablet being able to process a live view of HDR photography, complete with a comparison slider. The overall idea here is that every shot is an HDR shot, but Tegra 4 will also enable strobe motion, 3D reconstruction, and object tracking. Here's how they're architecting photography and a full press release.



NVIDIA Introduces World’s Fastest Mobile Processor


Tegra 4 Features 72 Custom GPU Cores, Quad-Core Cortex-A15 CPU for Superb Performance and Efficiency; LTE Enabled with Optional Chipset



LAS VEGAS—CES—Jan. 6, 2013—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

Wow! Just had a nerdgasm.

Largg says:

Can't wait to see Apple, Samsung and Qualcomm one up this processor!

hodan says:

Wow. They won't. And so much For Intel and AMD/ATI.

Nice warm-up to CES.

DjChameleon says:

I owned an LG G2X. Beautiful citing edge hardware with a near vanilla Android build and a Tegra 2 processor. I thoughtit would be awesome. I didn't realize that the proprietary drivers Nvidea insists on keeping control over would almost completely stymie even the geniuses at XDA from building a worthwhile ICS ROM. Never again will I ever buy another Nvidea powered device until they become developer friendly.

JFetch says:

It was a buggy pos phone. I don't blame Nvidia for it. I blame LG.

deltatux says:

Please please please, a dual-channel memory configuration. Tegra 2 and 3 sucked because it kept choking on a narrow memory bandwidth. Everyone except NVIDIA has dual channel memory.

Auzo says:

Yes, its dual channel. The leaked slides from a few days ago indicated as much.

Edit: And it's confirmed.

Mafiatounes says:

At last, this was really the bottleneck of previous Tegra soc's.

Nividia Tegra 4 this looks pretty impressive in theory. I wouldn't put any eggs in the Tegra 4 basket yet. First out the gate showing your wares is always cool but the BEST is always saved for last. And believe this it's not the Nividia Tegra 4 that's for sure....

TauSigmaNova says:

way to make my Nexus 4 feel obsolete

DWR_31 says:

They just made the One X+ obsolete.

JHBThree says:

Remains to be seen if this will be adopted by android oems given NVIDIA's refusal to offer their drivers up.

Also, this thing STILL lags behind the S4 pro because its LTE baseband is still separate. Totally inexcusable on NVIDIA's part.

admir91 says:

Can anyone let me know how this compares to the s4 pro quadcore since thats the fastest one out at the moment

mazzmoney95 says:

"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."

Is this really the world first quad core cortex a15 chip? I thought the Krait (s4) was a dual core a15 and the s4 pro was a quad core one. I'm probably wrong, since i dont think nvidea would lie like that.

Mafiatounes says:

You are a little bit off Qualcomm uses a self made Krait soc wich is different from Arm's A15 soc. We still need to see some good benchmarks to know wich one is better in terms of battery consumption and performance.

Rnwhite82 says:

Looks like I'll be rocking my Skyrocket until June-July. By then, something epic will be on the way... And I'll finally get my JB upgrade from ATT. :(

sweet! by the time my contract is up i sure as hell hope this is in the google play store. i could sure use some decent muscle in my phone.

sethoscope1 says:

Doesn't look like LTE is baked in. Guess we'll have to wait.

John-Smith says:

14 hours of HD video playback on phones.

Don't mean to sound negative, but I'll believe it when I see it..

I guess it can do 14 hours of playback with the screen off...
