Atom parts have long been the butt of our jokes for being the anti-performance parts that inspired the Netbook but anyone who ever tried to drive a Netbook for anything beyond browsing knows how much Atom’s sucked in performance. A dual-core, Hyper-Threaded 1.6Ghz Atom N2600 gives up a Cinebench 11.5 score of 0.47. That’s just barely faster than a single-core Athlon 64 3200’s score of 0.42. For reference, a Core i7-2600K gives up about 8.1 and a 3.2GHz Core 2 Duo E8200 gives you about 1.91. The actual performance isn’t known, but the new “Silvermont” version of Atom should offer far more performance than we've ever seen before.

Silvermont is significantly different from Atom architectures that have preceded it.
Ladies and gentlemen, meet Silvermont, the codename for the next generation of Intel's Atom line and the first in a family of yearly refreshes. Oh, and forget any preconceived notions you have about Atom, Silvermont is far different from the architecture found in your first or second generation notebook. It's a brand new design using Intel's 22nm 3D Tri-Gate SoC (System-on-Chip), which Intel claims will deliver "significant increases in performance and energy efficiency."
Intel is reportedly working on a new Atom-based micro-architecture codenamed "Silvermont" set to ship in 2013. The new chip architecture is based on Intel's recently announced 3D transistors and is supposed to enable better integration, performance, and power efficiency. As with all upcoming Atom chips, Silvermont will be a system-on-a-chip (SoC) design.
