On September 15th, Intel is expected to unveil its Xeon 7400 series Dunnington processor. What makes the server chip so special is it will be the first six-core processor, and likely the last Penryn to make a debut before the Nehalem microarchitecture takes over starting with the Core i7.
In another first, Dunnington will be the first Intel chip to sport a monolithic design, meaning all six cores will come on one slice of silicon. By contrast, the Core 2 Quad and four-core Xeon processors to date integrate two dual-core chips in a single package.
In addition to having six cores, the server market hopes to get big performance gains from the large 16MB of shared L3 cache. According to Intel senior vice president Pat Gelsinger, Sun Microsystems, Hewlett-Packard, and Dell will have product announcements related to the Xeon 7400 series in September.
