ZTE, Nvidia team up to launch Tegra 4 handsets in China

The Chinese phone manufacturer, ZTE, has teamed up with Nvidia to launch a line of quad-core smartphones slated for midyear or earlier. These handsets will feature the Tegra 4 chipset, which was unveiled last month during CES 2013.

Based on ARM Cortex-A15 architecture, Tegra 4 is expected to be much faster and more powerful than its predecessor, which was based on ARM Cortex-A9.

Tegra 4 also features six times as many graphics cores (bringing the total to 72) than its predecessor.

Along with building these quad-core devices, ZTE announced that it plans on making one phone that will also feature … Read more

Sharp to sell ultrathin IGZO 4K LED display

Sharp will begin sales of an ultrathin IGZO 4K LED display from early next year.

The Japanese display maker said Wednesday that it will launch sales of a Full HD 3,840x2,160 resolution 32-inch LED-backlit display starting on February 15, 2013.

Including the chassis, the model PN-K321 display is 35mm thick and compatible with DisplayPort and HDMI connectors.

Probably its most salient feature is the use of IGZO technology -- something Apple has had its eye on for the iPad because IGZO can yield very-high-resolution yet thin displays.

Sharp has a production target of 1,500 units a month. … Read more

Analysts: iPad 4's graphics upgrade packs a punch

At its silicon core, the fourth-generation iPad is hardly an incremental upgrade, according to chip analysts.

The new iPad's A6X chip packs a brand-new graphics engine that boasts a serious step up in horsepower from the third-generation iPad's A5X.

"Nothing's incremental about this. The A6X is one massive processing machine," Jim Morrison, a product manager at Chipworks, which does reverse engineering and patent-infringement analysis of semiconductors and electronic systems, told CNET.

Chipworks posted an analysis of the A6X's circuit layout today.

Apple's newest chip is a full 30 percent larger than the A6 … Read more

This could be the last hi-fi speaker you'll buy

Nothing gets older faster than high-tech, but the Harbeth P3ESR sounds so good you may never want to replace it with another speaker. That's no hype; I know audiophiles still using similar speakers originally manufactured in the 1970s.

That's when American audiophiles first fell in love with small British monitor speakers engineered and designed by the British Broadcasting Corporation (BBC), and manufactured by a number of companies, including KEF, Goodmans, Rogers, Spendor, and Harbeth. Though the speakers were all built around the same design, known as the LS3/5A, not all LS3/5As sounded exactly the same. Back … Read more

Inside Huawei, the Chinese tech giant that's rattling nerves in DC

SHENZHEN, China --Chen Lifang is a bit flummoxed.

Chen is a board member and senior vice president at Huawei, the giant telecommunications gear maker based here. She's digesting news that broke a day earlier that the U.S. House Intelligence Committee has increased the pressure it's putting on the company to disclose details about its ties to the Chinese government. The bombshell came in the form of a letter, released to the media, from the committee's chairman and the ranking Democrat to Huawei founder and Chairman Ren Zhengfei.

Really, the letter was more of an 11-page laundry … Read more

Qualcomm's Snapdragon S4 Pro to power LG quad-core device

Qualcomm announced today that a yet-to-be-unveiled LG quad-core phone will be powered by its own Snapdragon S4 Pro.

Though the company told CNET that it can't comment on the device until LG makes its an official announcement, it did say that the handset is "currently in production" and will be sold in Korea in September. It will launch globally sometime afterward.

Despite how little there is to know about the handset, we're excited nonetheless. And if it's going to be anything like LG's first quad-core phone, the LG 4X HD, it'll be sure … Read more

Quad-core Samsung Galaxy Note 10.1 tablet costs $500, $550

On the heels of last week's global launch, Samsung has officially announced U.S. pricing for its 10-inch Galaxy Note tablet.

The tablet, whose standout feature is its pressure-sensitive S Pen stylus and compatible apps, comes in two colors, deep gray and white. It also comes in two storage capacities. A 16GB model costs $499, but $549 gets you 32GB for your movies, music, photos, and apps.
