AMD Radeon HD 7970 unveiled as world's first 28nm GPU

AMD has taken the wraps of the Radeon HD 7970 graphics card. Billed as the world's fastest single GPU graphics card and the only GPU based on 28nm production technology, the new arrival pushes AMD ahead of NVIDIA in terms of miniaturization. The HD 7970 uses a new Graphics Core Next (GCN) architecture that AMD says results in a 150 percent performance/sq mm jump over the previous 40nm-based generation, is compatible with PCI Express 3.0 and features 3GB of GDDR5 memory and 925MHz engine clock. It also supports Direct3D 11.1 to be released with Windows 8.Read More

Creative announces Sound Core3D hardware audio processor

Over the years, Creative has expanded its business into media players, headphones and webcams but is perhaps best regarded for its Sound Blaster computer audio products. The X-Fi audio processing chip was added to its PCI cards in 2005 and now the company has announced the new Sound Core3D multi-core sound and voice processor. The low-power, high performance chip will come in a HD audio configuration for computer products and an embedded format for consumer electronics.Read More

Intel's 3-D transistors to keep pace with Moore's Law

NASA, the double-helix model, Elvis ... there's a long list of things that emerged during the 1950s which still resonate strongly in 2011, but none more so than the humble silicon transistor. Transistors are the bricks with which the shiny house of modern consumer electronics has been built, but for more than 50 years these bricks have been limited to two dimensions. Now there's a third. Intel has announced that it is putting its revolutionary Tri-Gate 3-D transistor into mass production. The first 22nm microprocessor (codenamed Ivy Bridge) to use the transistors will be rolled-out later this year, delivering huge gains in performance and efficiency compared with chips that use current 2-D planar transistors and helping keep pace with Moore's Law.Read More

Increasing processor efficiency by matching power with demand

For decades, chipmakers strove to develop the fastest and most powerful chips possible and damn the amount of electricity needed to power them, but these days raw grunt isn't the only consideration. As more and more devices go mobile and these devices become more and more powerful, chipmakers must also take the energy efficiency into account. Harvard graduate student Wonyoung Kim has developed and demonstrated an on-chip, multi-core voltage regulator (MCVR) that he says could allow the creation of "smarter" smartphones, slimmer laptops and more energy efficient data centers by more closely matching the power supply to the demand of the chip.Read More

Intel introduces second generation Core processors

Twenty new processors, new chipsets and new wireless solutions - including new Core i7, i5 and i3 processors, Intel 6 Series Chipsets, and Intel Centrino WiFi and WiMAX adapters - were introduced by Intel at CES today. The company brings a host of new features to the combined processor and powerful high definition graphics architecture, including super fast video conversion functionality and the ability to beam content to HDTVs via a new version of Intel WiDi. Collaborations with HD movie providers will also result in user being able to watch previously unavailable content on a PC screen.Read More

Intel introduces first configurable Atom-based processor

Intel’s range of ultra-low-voltage Atom processors have certainly staked their territory in a wide range of netbooks and tablets. In a move designed to make it easier for original equipment manufacturers (OEMs) to incorporate Atom processors into a wider range of devices, Intel has announced its configurable Atom E600C series. With differentiated, custom-made processors, Intel says OEM’s will be able to handle design changes and get their products to market quicker, without the need for complicated hardware changes.

Putting waste heat from electronics to good use

Researchers at two different institutions have recently announced the development of technologies for converting waste heat from electronics into something useful. At the California Institute of Technology (Caltech), they’ve created a silicon nanomesh film that could collect heat from electric appliances such as computers or refrigerators and convert it to electricity. Meanwhile, their colleagues at Ohio State University (OSU) have been working with a semiconducting material that has the capacity to turn waste heat from computers into additional processing power.Read More
