Computer maker Dell Inc.'s solution to the data center energy crisis is to market more energy-efficient versions of its PowerEdge line of servers.

The U.S. Department of Energy (DOE) chose IBM Corp. to build a new supercomputer for its Los Alamos National Laboratory in New Mexico, IBM announced Wednesday.

Intel Corp. unveiled its new Core 2 Duo processor lineup on Thursday, increasing the pressure on rival Advanced Micro Devices Inc. (AMD). The 10 new dual-core chips promise markedly better performance and greater energy efficiency than Intel's existing products.

With energy efficiency as the standard, Intel Corp. has announced a new multicore architecture that aims to address consumers' increasing need for better price and higher performance per watt for notebooks, desktops, and servers.
