45nm quad-core Xeons to run at up to 3.16GHz
AMD intends to start rolling out its quad-core Barcelona Opterons in the third and fourth quarters of this year, but Intel looks to have a potent retort in store. According to a roadmap nabbed by VR-Zone, AMD's arch-rival will strike back in the fourth quarter of 2007 with quad-core "Harpertown" Xeons based on 45nm process technology and running at speeds of up to 3.16GHz.
The top-of-the-line 3.16GHz Harpertown model will have a thermal rating of 120W, but Intel is reportedly cooking up low-voltage variants clocked at 2.33GHz and 2.66GHz with power ratings of just 50W. All quad-core Harpertowns will pack 12MB of L2 cache—6MB more than current Xeon 5300-series "Clovertown" models—and run on a 1333MHz front-side bus. For server users not keen to make the jump to quad-core, VR-Zone's roadmap says Intel will also have dual-core "Wolfdale-DP" chips clocked at up to 3.33GHz with thermal ratings of up to 65W.
