Intel Atom Z550

The Intel Atom Z550 is a power saving netbook / MID single-core processor. Compared to the Atom N-series, the Z-series supports Virtualization in hardware and got the Idle States and Demand Based Switching functions. Therefore, the Z-Series also has a lower TDP rating.

The Atom core was designed for a low power consumption and cheap production. The downside is the relative low performance per Watt (due to the in-order execution) compared to similar clocked Celeron processors, e.g.. Still the integrated Hyper-Threading (the operating system sees the CPU as a dual core CPU) decreases the penalty of the in-order execution a bit.
