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.

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

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 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

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.

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'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

Advanced Micro Devices will consider Android, but that's about all at this point.

Like Intel, the No. 2 PC processor maker has made its money selling chips that power Windows systems. Unlike Intel, however, AMD is not making any commitment to Android yet.

There's "no schedule for Android/Chrome support announced [and] no specific processors mentioned for support," an AMD spokesperson told CNET Wednesday.

But he added that "we have consistently said AMD is committed to applying our [intellectual property] anywhere where it makes sense for our business and our customers."

That's about … Read more

Here's some good advice. Wait for Intel's upcoming Silvermont chip.

In a demo Wednesday at Computex, Intel seemed to instantly -- and thoroughly -- obsolete the existing Atom, known as "Clover Trail," in a head-to-head "bake off," as the Intel demo guy put it.

The "current best-in-class Intel Atom-based tablet" (Clover Trail) was pitted against a tablet with the upcoming (and completely redesigned) quad-core Silvermont Atom (aka, "Bay Trail") packing a new "video encoder and decoder."

The benchmark, TouchXPRT, tests "performance of everyday [tasks] such as photo … Read more
