SOA World Magazine published some details of Intel's Dunnington, an upcoming server processor with six cores. Dunnington will be based on the 45nm Core 2 architecture.
Dunnington, a Bangalore-designed successor to Harpertown, is still supposed to be relatively hush-hush but Intel has reportedly put three dual-core 45nm Penryn chips on a die the size of a postage stamp and sharing a 16MB L3 cache. Like other Penryns, Dunnington still uses a front-side bus.
Dunnington slips into Intel’s Caneland platform and so uses the Clarksboro chipset.
The dingus, which Intel has previously described as pin-compatible with the dual-core/four-socket Tigerton quad, will be two- and four-socket, meaning mainframe-like machines with 24 cores.
Intel is reportedly seeing how quickly it can get the little beast out. It was due before the first of the Nehalem chips and could appear in Q3, maybe even Q2.
Dunnington doesn’t require the record two billion transistors that it takes to make Intel’s next-generation 65nm quad-core Tukwila Itanium, but it’s reportedly close.
Dunnington will appear in a variety of SKUs and a variety of clock rates with power dissipation that ranges beyond 120W.
