Two 650MHz notebooks with SpeedStep compared

Intel's new range of mobile processors (also available running at 600MHz) boost not only the raw performance of notebooks, but offer power consumption and heat reduction improvements. SpeedStep technology provides the full 600MHz and 650MHz speeds to the processors under AC power but drops performance to 500MHz when operating on batteries - a good compromise between performance and mains-free operational time. Of course, should the extra 100-150MHz when running on the battery be required, users can manually override the SpeedStep.

In addition, the processors use 0.18 micron technology, a 0.07 micron fabrication improvement from the previous 0.25 micron Intel standard: this permits higher performance, and reduces power consumption and hence heat generation.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
