Poulsbo is a chipset for Intel's first generation of Atom processors based on the Bonnell microarchitecture.


Comparison between the two Poulsbo packages.

The Poulsbo chipset, part of the Menlow, offers the memory controller along with the much of the southbridge. Unlike all previous front-side bus signaling logic which used GTL, to allow for more power saving, Poulsbo became the first chipset to support CMOS signaling as well. Such functionality was only offered by the Silverthorne-based processors. In 2009 Intel released a second variant of Poulsbo in a larger package.
