DC Power Poised To Bring Savings To Datacenters 287

snydeq writes "InfoWorld's Logan Harbaugh follows up his '10 IT Power-Saving Myths Debunked' to argue in favor of using DC power in the datacenter. The practice — viewed as a somewhat crackpot means for reducing wasteful conversions in the datacenter just a few short years ago — has gained traction to the point where server vendors such as HP, IBM, and Sun are making DC power supplies available in their server wares. Meanwhile, Panduit and other companies are working to bring down another barrier for DC to the datacenter: a standardized 400-VDC connector and cabling solution. And with GE working to list 600-VDC circuit breakers with the Underwriters Labs, DC's promise of reduced conversion waste could soon be commonly realized."

45nm Phenom II Matches Core 2 Quad, Trails Core i7 234

An anonymous reader writes "AMD recently debuted its 45nm Phenom II processors, and The Tech Report has already run them through a complete suite of benchmarks to see how they perform compared to Intel's latest and greatest. The new 2.8GHz and 3GHz Phenom IIs are in a dead heat with like-priced Core 2 Quads, but they generally fall well behind Intel's new Core i7 chips. TR concludes that AMD's future doesn't look as bleak as some say, and future Phenom IIs could compete favorably with more affordable Core i7 derivatives."
