Nvidia's new Tegra K1 chip features a quad-core CPU and a 192-core GPU

A year after introducing the world to the mighty Tegra 4 mobile chip, Nvidia has pulled back the CES curtain on a new member of the Tegra family. The company says that the Tegra K1, which boasts a quad-core CPU and a whopping 192-core GPU, should open the door to next-gen PC-class gaming on hand-held mobile devices.  Read More

A 110-core CPU chip has been developed by computer scientists at the Massachusetts Institute of Technology. The chip is based on a new architecture in which instead of bringing data across the chip to the core that happens to want it, you move the program to the core where the data is stored. In practice, this new architecture reduces the amount of on-chip data exchange tenfold, along with the heat and infrastructure demanded by conventional chip architecture.  Read More

Undetectable hardware Trojans could subvert cryptographic security (Image: Shutterstock)

Researchers have shown that it is possible to compromise the functioning of a cryptographic chip without changing its physical layout. Based on altering the distribution of dopants in a few components on the chip during fabrication, this method represents a big challenge for cyber-security as it is nearly impossible to detect with any currently practical detection scheme.  Read More

In a technological tour de force, researchers at Stanford University have constructed a one-bit, one-instruction programmable computer on a chip using carbon nanotube-based electronics for all logic elements. Containing 178 carbon nanotube field-effect transistors, the computer is only able to carry out only one instruction, called SUBNEG. However, SUBNEG is Turing-complete, allowing the computer to run, albeit with an extraordinary level of inefficiency, any program, given enough memory, time, and programming ingenuity.  Read More

We've known for a while that the PlayStation 4 will release on November 15 in the US. But what about the Xbox One? Up until today, we only had vague references to "November." Well, Microsoft finally spilled the beans on the Xbox One's release date, along with some details about the console's processor and production status.  Read More

Apple is reportedly moving further away from Samsung, sourcing TSMC for some of its next-g...

The relationship between Apple and Samsung is, well, complicated. They're like two bitter exes who work together, or maybe live in the same building. If circumstances permitted, they'd never see each other again. But, try as they may, they just can't get each other out of their lives. Can you say awkward? Well, that relationship is about to take one step closer to complete severance, as Apple is reportedly partially switching to TSMC for the coming year's iOS processors.  Read More

Intel has introduced its 4th generation Intel Core processors

Intel is apparently convinced that the future of computing is mobile. Having announced its new Atom Silvermont architecture last month, the chipmaker has introduced its 4th-generation Intel Core processors (code named Haswell), with much of the focus on the power savings that will benefit the battery life of mobile devices. Designed with a new generation of Ultrabooks in mind, Intel says its new processors will provide up to nine hours of battery life with up to two times the graphics capability of previous generations.  Read More

D-Wave's 512-Qubit Vesuvius quantum computing chip can match it with massively parallel su...

There have been years of controversy about whether the superconducting quantum annealing computers manufactured by D-Wave are a) quantum computers; and b) fast enough for a) to matter. Now a test of the 512-qubit Vesuvius chip establishes at least that computing based on quantum annealing is, in the words of a computer science professor at Amherst College, "in some cases, really, really fast."  Read More

Intels' new Silvermont architecture promises three times the peak performance of current-g...

ARM is currently king of the hill when it comes to mobile devices, with ARM architecture the basis of processors and systems on a chip (SoC) including Qualcomm’s Snapdragon, NVIDIA’s Tegra, Texas Instruments’ OMAP, the CORTEX series and Apple System on Chips found in iPhones and iPads. It’s obviously not a situation Intel is happy with and the company has high hopes that its new Atom chip design called Silvermont will help change the mobile silicon landscape.  Read More

The new Snapdragon chips promise much faster performance than its predecessors (unknown ch...

Some of the biggest names in tech are absent from CES 2013. Apple, Google, and Microsoft may have skipped the trip to Vegas, but the chips that power (some of) their devices are there in full force. NVIDIA and Intel have already showcased new mobile processors, and tonight it was Qualcomm's turn, as the silicon-maker unveiled its new Snapdragons.  Read More
