At the VMWorld Conference in Las Vegas, Intel will possibly release a six-core Xeon 7400 processor codenamed Dunnington. Aimed at the blade/server segment, this six-core chip is manufactured on the tick 45nm process, and will be the last chip in the Penryn lineup.
Dunnington has each core sharing 3MB of L2 cache with access to 16MB of L3 cache. Frequently used instructions can be stored in these large memory caches to reduce bottlenecks. The Thermal Design Power rating is approximately 130W, and the chip supports 1066 MegaTransfers per second interconnectivity and new SSE4 instruction sets.
At Intel Developer Forum last month, Pat Gelsinger, senior vice president and co-general manager of Intel's Digital Enterprise Group announced that Intel servers had broken multiple world performance awards. The Dunnington chip will precede Nehalem chips which will come in two, four and eight cores with integrated graphics.
