The Tech Report spotted a rumor that Intel may be working on an eight-core Atom for servers. The chip is reportedly based on the 22nm Silvermont Atom core, which is rumored to offer 20-25 percent better clock-for-clock performance than the current Atom. The codename of this eight-core Atom is said to be "Avadon" or "Abadon". Expected availability is 2013.
Silvermont is slated to be built using 22-nm process technology—tri-gate transistors and all. SemiAccurate says the eight-core chips won't arrive until late 2013, though. That seems like a reasonable timeline given the fact that the first Silvermont-based Atoms, which will have fewer than eight cores and be targeted at netbooks and tablets, are expected in 2013. While Intel didn't mention an eight-core version at IDF a couple of months ago, it did confirm that Silvermont would debut in 2013.
