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.

Review Sony Vaio VPC-X13D7E/B Subnotebook

761 Gramm.We'll take one ultra-light mini, preferably small and without too much on the side. Those who are satisfied with basic notebook features but are still looking for striking exterior are right on target with the 11.1 inches.
