Mobile AMD Athlon 64 processor

The AMD Athlon 64 was the first consumer 64-bit processor for a portable PC, a feat the Intel has only recently achieved.

Like the Turion 64 X2, this processor is also capable of running both 32-bit and 64-bit software. The Mobile Athlon 64 features AMD PowerNow! Power management technology, supports Windows enhanced virus protection and uses AMD's HyperTransport technology for FSB speeds up to 1600MHz (full duplex). Mobile AMD Athlon 64 performance processors each have 1MB of Level2 cache and speeds ranging from the 1.6GHz 2800+ up to the 2.6GHz 4000+. Each Low Power Mobile AMD Athlon 64 processor features a 512KB Level2 cache. This range includes the 2700+ (1.6GHz), 2800+ (1.8GHz) and 3000+ (2.0GHz). For more information on AMD processors, see the company's Web site.

Mobile AMD Sempron processor

AMD's Sempron

Directly targeting Intel's value-orientated Celeron M processor, AMD's 32-bit Mobile Sempron processor is a vast improvement over its earlier Mobile Duron efforts and should help notebook vendors with the ability to produce inexpensive, thin and light notebooks.

That said, the Mobile Sempron processors have 128KB of Level1 on-chip cache - twice as much as Intel's Celeron M processors. However, Intel's Celeron M processors have much more Level2 cache (1MB compared to the Sempron's 128KB-256KB, depending on the model).

Mobile Sempron processors offer AMD PowerNow! Power management technology and supports Windows enhanced virus protection.

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.
