First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
Sapphire Radeon HD 5850 graphics card
Following in the only slightly larger footprints of the sizzling 5870 graphics card comes this downscaled version, the Sapphire Radeon HD 5850 1GB
The Radeon HD 5870 first showed us the joys of ATI's DirectX 11.0 technology, but it was the 5850 that shoe-horned it into a package that offered real value for the fervent gamer.
- Excellent value for money, good performance
- Less well-equipped for future use than more expensive cards
The Sapphire Radeon HD 5850 1GB boasts plenty of power, with many of the same features as the 5870. The clincher, though, is the price. Four hundred dollars is fantastic for a card hard on the heels of a GTX 295 or HD 5870. If you're shopping anywhere near to this price point, nothing tops the ATI HD 5850.
Price$ 406.00 (AUD)
Both graphics chips are manufactured using the 40nm process. The 5850 is a little shorter than the 5870, but it also runs cooler and consumes less power at 151W under maximum load. It requires a pair of six-pin power connectors. You get both HDMI and DVI ports, and the 5850 can support up to three screens. Eyefinity adds the ability to stretch some games across those three displays.
The basic architecture is based on a 256bit memory interface. The specifications have been trimmed slightly, so the 5870’s 850MHz core clock becomes 725MHz in the 5850. The memory clock speed has been turned down from 1.2GHz to 1GHz, and the number of stream processors is sliced from 1,600 to a still impressive 1,440. All this should give the 5850 the edge over both the GTX 470 and 480. Its floating point of 2.09TFlops is almost twice that of the GTX 470’s 1.09TFlops, while the fill rate sees it beat even the GTX 480 by more than 10.2GTps. This is due to a generous sampling of texture units.
But superiority on paper doesn’t always result in a commanding lead in real-world performance. The 5850 is a slower card than the GTX 470, but the difference wasn’t as great as the $100 price gap might suggest. In Hawx, it trailed by around 8 to 12fps, but in Aliens vs Predator the difference was less than 2fps as detail levels were raised. Our Crysis tests occasionally saw the 5850 beat its rival.
Of the $350-plus cards we've tested recently, the 5850 saw the greatest drop in performance when moving from DirectX 10.x to 11.0. We suspect this card will have few problems with future DirectX 11.0 games, however.
The 5850 is slower than the GTX 470 in most tests. But it costs less and runs cooler and quieter.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.
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.
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.
