Grooves writes "Intel has said that the company is stepping up the pace of its Core 2 architecture rollout to compete with AMD's 4x4. Two "quad-core" parts originally slated for release in the first half of 2007, Kentsfield for the desktop and Clovertown for servers, will make their debut as early as the end of this year. The Ars article warns that per-core bandwidth problems could end up giving a performance advantage to AMD's 4x4 approach."
