AMD finally launches Phenom II and Dragon Platform

AMD's 45nm, quad-core Phenom II has finally arrived. It's available in two flavors, the 2.8GHz X4 920 and the 3.0GHz X4 940 Black Edition, going for $235 and $275, respectively. AMD's naturally touting the ostensible cost savings of the chips . The Dragon platform includes a Phenom II proc, 4800-series Radeon HD graphics and a 790-series motherboard, all of which should combine for low power consumption -- up to 40 percent compared to Phenom processors. Where the Phenom II definitely wins is the fact that some AMD folks will be able to drop in the chip to existing motherboards, but otherwise it looks like value hounds and performance junkies aren't being served by this new chip.

Performance

The Phenom II's integrated memory controller and HyperTransport interface give it a technical edge over competing Core 2 Quad chips, which lack those features. Intel moved to an integrated memory controller and began incorporating its own version of HyperTransport--dubbed QuickPath Interconnect--only with its Core i7 platform. The integrated memory controller and HyperTransport interface allow Phenom II processors to achieve a higher memory bandwidth than Core 2 Quad processors can, by eliminating the bottlenecks created by a frontside bus and an external controller. The arrangement, in theory, improves system performance.
