Intel is coming out with the details of its eight-core Xeons, code-named Beckton, although it's unlikely we'll be seeing the devices in any enterprise-class machines until 2010. The company is set to discuss the chips at the Solid-State Circuits Conference next month in San Francisco. Details released so far talk about a 16-thread device based on the Nehelem architecture, with 2.3 billion transistors with four point-to-point path interconnects and an overall system I/O of 6.5 GTps.
The chip will have a built-in four-channel memory controller, although there's no word yet on cache sizes. Current i7 chips have 731 million transistors and contain 1 MB of L2 cache and 8 MB of L3.
