Boffins from Arizona State University have demonstrated a microrefrigerator which effectively cools a PC system by targeting specific chip hot spots.

From budget laptops to ultra-tiny netbooks, ultraportables and high performance, we explain the tricks to finding out the ultimate laptop at the right price.

Will AMD blow its lead again in graphics? An analysis of the current state of play in the race for processor and graphics superiority

Want to perform an extreme makeover of your system's motherboard, processor, memory or hard disk? We'll show you how.

Impressive and free antivirus and antispyware package

Intel has released a short animated video illustrating the process by which sand is turned into silicon and a CPU. But the over-simplicity has us leaning towards AMD's older and more interesting video

When it comes to platforms, AMD's senior VP likes to think his firm has better offerings than its arch-rival Intel, and says this fall will be "very exciting" for his company.

Intel's Netburst might have become a retrospective embarrassment for the firm, but CPUs based on the best-forgotten architecture are apparently still hitting sky-high clock speeds.

From Celerons to Core i7s, Semprons to Phenom IIs, David Bayon tests Mainsteam desktop processors and finds the best budget, mid-range and enthusiast (gaming) choice for you.

Curious to see what powers the Nehalem and Core i7 architecture? We reveal the tech behind the fastest Intel-powered computer on the planet.

Here's what's in store for 2010, including Intel's big gun - the Clarkdale CPU - and the highly anticipated new netbook platform

Nvidia reckons Open CL and Direct X are key to operating system acceleration on the GPU and claims GPGPU (general-purpose graphics processing units) will allow for serious speed-ups of Microsoft's Windows and Apple's Snow Leopard.

The battle between portable devices is heating up.

AMD may be first to ship Direct X11 compatible graphics cards onto the market in a huge play for the company. It's hoped that the codec will encourage better support for HD and 3D content, particularly amongst Windows 7 users.

Intel's Atom platform may provide the backbone of today's netbooks, but with rivals emerging, Intel could find itself playing a smaller part in the future, as players such as Nvidia's Tegra take hold.

AMD has updated its laptop roadmap, but don't expect major changes in what you see until the end of 2010.

AMD’s next generation of CPUs brings 45nm technology and higher clock speeds - but is that enough to compete with Intel’s latest and greatest?

Nvidia’s remix of the popular netbook platform lends Intel’s stripped-down Atom some added Graphical clout. We test the technology to see how it performs

Several PC makers expect to have Nehalem-EX 16-core DP desktops, in fact super workstations, at the chip's launch towards year-end

ATI today is announcing its new Stream transcoding paradigm, and unlike some others, it makes quite a bit of sense. Stream now parses workloads between the CPU and the GPU, and does things much more intelligently.
