Operation overdrive: 1GHz notebooks on assignment

Although the PIII 1GHz processor has existed for the desktop for quite some time now, the mobile processor has features and characteristics that distinguish it from its desktop cousin and enhance the mobile experience in ways that the desktop processor can not.

One of the major distinguishing factors between the desktop and mobile 1GHz processors is the use of SpeedStep technology. In effect, this allows the 0.18-micron Pentium III processor within a notebook to vary its clock speed and the amount of voltage it requires to operate, thereby enabling greater battery life when away from an AC power outlet. In Battery Optimized Mode, the 1GHz Pentium III mobile processor compromises only part of its total performance by dropping from 1GHz operating at 1.7V to 700MHz operating at 1.35V. A drop in processor power works in conjunction with a drop in the amount of voltage required to operate the processor, resulting in longer battery life.

Many of the major notebook vendors have come to the mobile 1GHz party and we have a sample set of five systems from Acer, Dell, Gateway, IBM and Toshiba. This gives a good indication of the types of notebooks that will ship with these processors and the features that can be found on them. For the most part, these were desktop replacement systems with large screens, generous hard drives and very high-end graphics adapters. Other features varied wildly, from DVD-ROM and CD-R/RW drives to biometric security features and built-in WiFi and Bluetooth aerials, plus other goodies such as IEEE 1394 FireWire connectivity and S/PDIF digital audio out.

    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.
