When it comes to Intel, the Ultrabook segment is not only confined to compact travel companions, but should also include devices that can even serve as a desktop replacement. They are, of course, somewhat heavier and they can be up to 21 millimeters thick.

A low-voltage core processor, a long battery life and the fast system start are also the XL Ultrabooks specifications, which must be adhered to by the manufacturers so that the mobile computers may call Ultrabook. We've tested seven major ultrabooks from Acer, Dell, HP, Lenovo, Samsung, Toshiba and Wortmann.
Test methods Ultrabooks
Mobility is crucial
Conclusion
Ultrabooks are mainly mobile devices for the road. Therefore, the battery charging time, the charging time and the weight of the devices are included in the evaluation with a total of 30 percent. We calculate the runtime under full load and the charging time with BatteryEater, the MobileMark 2007 simulates the work with different office and image processing programs. WLAN and Bluetooth are disabled, screen brightness is reduced to 60 percent.
Extensive performance measurements
For the performance measurements we use the Futuremark 3DMark Vantage in performance mode on an external monitor. We determine the system performance of the Ultrabooks with the PCMark Vantage, which performs an application mix, which also plays a role in 3D performance and disk performance. The Cinebench R11.5 rendering benchmark provides information about CPU performance. HD-Tune 2.61 is used to measure the transfer rate and access time of the hard disk.
The test winner is the sleek and elegant Samsung 900X4C. It delivers balanced performance, a very good battery life, and a good 15-inch panel. If you want to play with an Ultrabook, the Dell XPS 14 is well served. If size and weight do not matter, then the Acer Aspire M5 is the right choice. It delivers the best 3D performance and battery life, but also weighs 2.3 kg.
