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.

Reviews for the Intel Atom Z520 processor

 

Review Asus Eee PC T91 MT Tablet

Has Asus turned the corner in tablet design? While other companies offer larger, higher performance tablets at a premium price, Asus has remained focused on netbook-style size and performance with its T91 MT, appealing to a much broader market with the relatively low price of €500. We took a closer look at the convertible tablet; find out what we uncovered in this review.

Review of Asus R50A UMPC

Always at hand. With the Asus R50A the Microsoft Origami project sends its greetings. Origami Experience 2.0 is a software package that is specifically designed for Ultra-Mobile PCs by Microsoft. Based on Windows Vista, this allows ad-hoc access to required information on the go. The included WWAN 3G HSDPA module and GPS also meets the mobile communications character. All together the successor of the Asus R2H, and competitor of the Samsung Q1 Ultra, provides modern technologies, several useful features, and a navigation system in a pocket sized format.

Review Asus Eee PC 1101HA Netbook

The Eee PC netbook has grown! 'Netbook inventor' Asus presents its latest achievement in the Eee PC 1101HA. Although Asus is constantly expanding and adapting its range of small and mobile mini-notebooks, the difference here is clear from the first glance. For the first time, the netbook pioneer has produced a larger WXGA screen, at 11.6 inches. But despite the inevitable increase in size and weight, the Eee PC 1101HA is still focused on portability above all else. Read on to see how this €399 machine fares in our tests.

Review Acer Aspire One 751 Mini-Notebook

Wide, light, and enduring…Acer brings into play a format so far untypical of netbooks with the 11.6" Aspire One 751 and calls it a "Widescreen Netbook". Image and sound are supposed to be rendered especially "breath-taking" through this niche-modell, not leaving anything to be desired. Our review shows how the new form factor acquits itself in practice and compared to the competition.

Review Sony Vaio VGN-P21Z Mini-Notebook

Pocket Size. An ultra-compact and light notebook as a permanent chaperone, perpetual access to internet, never again computer-free time? Sony also makes their contribution to make this lifestyle reality come true with its VGN-P series in an eight inch format and hopes that they will attract a wide range of potential buyers with their stylistic mini-devices. We are taking a closer look at the white Sony Vaio VGN-P21Z in the following review.
