Intel Atom Z520

The Intel Atom Z520 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.

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.

The performance of the Z520 is only compareable to a 800-900 MHz clocked Celeron M and therfore only sufficient for non demanding applications like Office or web surfing. HD videos, advanced photo editing, video cutting may not run fluently.
