Long after Intel introduced its 65nm chips, AMD has also rolled out its nice little collection of Athlon 64 X2 dual-core desktop processors. The X2 4000+, 4400+, 4800+ and 5000+ are all available now, and priced from $169 to $301. The company predicts that this new line up consumes half the power of that of Intel's Core 2 Duo chips. These are a great processor chips, which boasts superior power management features and are being offered at a good price. Notebook chips should follow in the first half of 2007.

May be with this move, AMD wants to catch its rival Intel, but I doubt it as Intel is already working on its 'Penryn' 45nm Chips with much improved features and sophisticated design.
