Intel's TV 'Black Box Project' poised for big changes in debut

Thousands of Intel employees have exclusive trial access to the company's up-and-coming TV service, but what they're using is leaps away from the final product, CNET has learned.

As CNET earlier reported, Intel in late March started conducting closed trials of its Internet TV service and set-top box with company employees in three West Coast markets. We've now learned more about that test program, code-named the "Black Box Project."

Currently, more than 2,000 Intel employees in Northern California, Arizona, and Oregon are testing the product in their homes, people familiar with the matter told … Read more

Nvidia to license its graphics technology to device makers

Could Apple tap Nvidia for graphics power in its mobile devices? Maybe, now that the chipmaker has decided to license its graphics technology.

Nvidia on Tuesday said it would begin licensing its GPU cores and "visual computing" patent portfolio to device manufacturers -- a new business model for the company. The technology could appear in a full range of products from phones to supercomputers, the company said, with products likely emerging in 2015, given design and testing requirements.

"It's not practical to build silicon or systems to address every part of the expanding market," David … Read more

AMD to launch its first ARM chip

Advanced Micro Devices is dipping into the ARM world.

The chipmaker announced Tuesday that it plans to develop its first ARM chip starting next year. Codenamed "Seattle," the chip is being touted by AMD as the industry's first 64-bit ARM processor from a major chipmaker.

AMD said that the chip will offer two to four times the performance of its Opteron X-Series processor with improved compute per watt. Based on the ARM Cortex-A57 processor, Seattle is expected to run at speeds of 2 gigahertz or higher and will support up to 128GB of DRAM.

Aimed at the … Read more

Nvidia's graphics brawn powers supercomputing brains

Nvidia, trying to move its graphics chips into the supercomputing market, has found a niche helping engineers build brain-like systems called neural networks.

For years, the company has advocated the idea of offloading processing tasks from general-purposes central processing units (CPUs) to its own graphics processing units (GPUs). That approach has won over some researchers and companies involved with neural networks, which reproduce some of the electrical behavior of real-world nerve cells inside a computer.

Neurons in the real world work by sending electrical signals around the brain, but much of the actual functioning of the brain remains a mystery. … Read more

Chinese supercomputer tops the charts -- two years early

Performing more than 33 quadrillion calculations per second, a new Chinese supercomputer called Tianhe-2 arrived two years earlier than expected to claim the top spot in a list of the 500 most powerful supercomputers in the world.

The Top500 list, updated twice a year at the International Supercomputing Conference, measures performance for mammoth systems typically used for jobs like modeling nuclear weapons explosions and forecasting global climate changes. And the Chinese machine, at the National University of Defense Technology, is more mammoth than most.

The Tianhe-2 has 32,000 Xeon processors boosted by 48,000 Xeon Phi accelerator processors for … Read more

Nvidia: Next-gen consoles still can't keep up with our chips

Nvidia doesn't seem happy with news that Advanced Micro Devices has all but won this generation's console cycle.

The company pointed out Wednesday in an interview with The Verge that, while the next-generation consoles are notably more powerful on the graphics side, they still can't compete with the chips Nvidia is producing on the PC side.

"I'm glad the new consoles are here," Nvidia Senior Vice President Tony Tamasi told The Verge. "If for no other reason than to raise the bar." He also pointed out to The Verge that his company'… Read more

Inside the 2013 MacBook Air: SSD sizzles, graphics gain

It may look the same outside, but the MacBook Air got overhauled on the inside.

In the case of the solid-state drive (SSD) and graphics, it's a major overhaul.

SSD: Apple appears to be one of the first to stick a PCI Express (PCIe) SSD in a thin laptop. And that makes a huge difference, according to Anand Shimpi of Anandtech.

"This is a huge deal, totally the future. And pretty much all other notebooks announced at Computex still use [Serial ATA]. Apple did the right thing here," Anand said in response to an e-mail query.

Writer's block: Cursing the cursor on Apple, Google tablets

Google makes a great tablet. But Apple does too. Neither are great writing platforms, though.

After picking up the Nexus 10 a while back, I've been finding it hard to put down. It's lighter and thinner than the 9.7-inch iPad 4 (and it certainly feels that way), it's fast (packing Samsung's latest dual-core A15 with quad-core graphics), has more system memory (2GB), has a gorgeous screen (boasting even higher resolution than Apple's Retina), and comes with the latest version of Android (4.2) -- also very likable.

Like I said, it's very hard … Read more

Intel tablet keeps tabs on your heart rate

Intel's perceptual computing isn't just fun and games.

In the past year or so, Intel's demoes of perceptual computing have focused on interacting with the computer in the 3D space in front of the device. It's not unlike the motion-sensing Kinect gaming technology from Microsoft, which allows interaction via gestures.

Well, that same sensing technology does more than just games. Using "sophisticated computer vision algorithms" Intel showed a tablet monitoring a person's heart rate (see image at top).

"When oxygenated blood comes to my face, we can't see it with our … Read more
