There's no official word yet, but there's speculation that Intel might release it's six-core Dunnington chips next week at VMWare's VMWorld conference in Las Vegas. Dunnington isn't being aimed at the desktop crowd and will instead target the server market, so if Intel was looking to make a splash with its new CPUs before Nehalem debuts, VMWorld would be the place to do it.
For those that missed our coverage earlier this month, Intel's Xeon 7400 series Dunnington processor will not only be the first six-core CPU, but also the first Intel chip to sport a monolithic design, meaning all six cores will come on one slice of silicon. Current generation chips feature multiple cores in one package. Despite being monolithic in nature, Dunnington will still use an external memory controller, which Intel hopes to offset with a generous amount of cache. The six cores will share a beefy 16MB of L3 cache, and 3MB of L2 cache (9MB total).
