Intel is expected to announce their new 6-Core Chip called the Dunnington. Dunnington is the first six-core processor and last of its Penryn-class chips. On September 15, Intel is expected to roll out the Intel Xeon 7400 series Dunnington processor targeted at the server market, the final member of the “Penryn” family of processors, according to sources at server vendors. Penryn will be followed by the Nehalem microarchitecture, due to appear initially as the Core i7 processor in the fourth quarter.

The Xeon 7400 Dunnington  is the last CPU of the Penryn generation and Intel’s first multi-core (above two) die - will feature a single-die six core design with three unified 3 MB L2 caches (resembling three merged 45 nm dual-core Wolfdale dies), and 96 KB L1 cache and 16 MB of L3 cache. It is expected to feature 1066 MHz FSB, fit into the Tigerton’s mPGA604 socket, and be compatible with the Caneland chipset. These processors are expected to support DDR2-1066 (266 MHz), and to have a max. power consumption below 130 W.

“Dunnington is the first IA (Intel Architecture) processor with six cores, is based on the 45nm high-k process technology, and has large shared caches.” says Intel [via Cnet]
