Dell promises to save energy

Dell vowed its desktops and laptops will use 25% less energy by 2010, says Computerworld.

"Our customers are inspiring us to address the environmental challenges facing our planet," said Albert Esser, Dell's VP of power and infrastructure solutions, in a statement. "We've listened to them and are designing next-generation technologies that dramatically reduce energy consumption, drive meaningful cost savings and help achieve a low-carbon economy."

Dell noted in a release that it plans to trim energy usage by changing the circuit designs, fans and power management features in its computers. The company said it is also working with its vendors to get more energy-efficient components, like chipsets, power supplies and memory.

OCZ's DIY Gaming Notebook includes the basics: a 15.4-inch WXGA display, an Intel PM965 chipset, an Nviida GeForce 8600MGT/512MB video card, and an 8X DVD+/-R/RW combo drive capable of reading and writing four-layer discs, reports PCMag.com.

However, it falls to the user to buy and install the CPU, memory, hard drive and operating system, either from OCZ or from elsewhere on the Web.

The idea is that in exchange for a little elbow grease, a customer can end up buying the specific CPU he or she wants from other vendors, without paying OCZ a mark up for providing and installing it.

The basic desktop PC in 25 years will have a 100 000-core processor, a million gigabytes of memory, and 100 million gigabytes of storage, according to the chief technology strategist at Fujitsu-Siemens, says Personal Computer World.

Dave Pritchard says clock speeds may still hover around 3GHz to 4GHz, but aggregated over the cores they will be equivalent to three million gigahertz.

Internet access speeds will be of the order of 250GBps, he says, on the basis of Nielsen's Law, the prediction by Sun engineer Jakob Nielsen that bandwidth to prosperous homes will increase by 50% a year.
