Notebookcheck's Top 10 Ultrabooks

Staff (translated by Andreas Osthoff), 01/17/2015

January 2015 update. Here you will find the best ultrabooks reviewed by Notebookcheck in the last few months. Our list of top models is regularly updated, maintained and commented on and should assist in purchase decisions.

Intel initiated a new class of notebooks at the beginning of 2011, the so called ultrabooks. Notebook manufacturers could use the protected designation "Ultrabook" if they met some requirements, for example for the CPU (Intel Haswell ULV), battery runtime (6 hours FHD playback) and dimensions (<21 mm). Therefore, this notebook class mainly consist of very mobile devices with slim cases yet sufficient performance (Core i processors) for almost every display size. The latest versions also integrate a touchscreen.
Some of our review samples did not have a touch panel, but in this case there are also configurations with an optional touchscreen. The corresponding devices are marked since there could be different ratings with optional touchscreens.

The following table shows an overview of the Top 10 ultrabooks reviewed by Notebookcheck in the previous 10 months. If ratings are equal, the latest review is listed first. The table can be sorted by clicking its headers and filtered by entering text in the text field above it (e.g. "matte").

Workhorse: HP EliteBook 840 G1
Workhorse: HP EliteBook 840 G1

1st

HP has a suitable piece of hardware for the mobile business customer: The EliteBook 840 G1. There are several configurations, so you can adjust the EliteBook perfectly to your individual needs. The high-quality and sturdy chassis, very good input devices and comprehensive communications and connectivity options are pretty much standard in this product class. Depending on the usage scenario, the Intel CPU can be complemented by a dedicated GPU, and there is obviously almost every possible storage solution available. Our review focuses on the non-touchscreen version with a matte panel. The alternative touch display has a lower resolution (1366x768), but according to HP, it also has matte surface.

Do things in a big way. With the NX500JK-DR018HAsus  offers a new Zenbook model. This time it is a 15.6 incher. For 2200 Euro, the demands on this notebook are especially high and it cannot  meet all of them. The 4k panel is top in the pro list with very good colors, high brightness and high contrast. The aluminum chassis belongs to the best ones besides the Macbook Pro's. The keyboard quality is also high and it is apt for prolific writers. The battery life of six hours in the WLAN test is very good for the performance class. But the performance of GeForce GTX 850M and Core i7 4712HQ is lacking. The CPU does not use its Turbo potential (standard volt quad core) by far. The small performance loss can also be seen in benchmarks. The gaming performance of the GTX 850M is not affected, but it is a mid-range GPU. In contrast, the ergonomics is good with cool surfaces and a steady, largely quiet double fan. The maintainability sticks out positively. All components including battery can be reached via bottom plate.

3rd

The highly mobile business line from Toshiba is called Portégé and the Portege Z30t is an ultrabook with a very interesting display. It has a 13.3-inch display with a high resolution of 1920x1080 pixels and also has a very convenient matte surface with touch support. Thanks to the IPS technology, it offers wide viewing angles even in extreme situations and a good color presentation. With a weight of just 1.4 kilograms and a battery runtime of around 8 hours in practice, the Z30t meets the requirements of a mobile device. There are also several alternative configurations and you can also choose a non-touch version.

Best Value Award in December 2014: Asus ASUSPRO Advanced BU201LA
Best Value Award in December 2014: Asus ASUSPRO Advanced BU201LA

4th

A handy business device can also come from Asus. The 12.5 inch ASUSPRO Advanced BU201LA-DT036G is indeed surprising. The small business device only costs just under 800 Euro, but brings (almost) all features of a professional device: trackpoint, fingerprint reader, DisplayPort, matte FHD display, Smartcard slot, backlit keys, and TPM chip. In addition, the brightness is very good, the viewing angles are wide (IPS), the key feedback is strong, and the chassis is a pleasure. The short battery life of only 3:38 hours (WLAN test) is a disadvantage. Asus achieved more than a decent result and the price is much better than of more expensive competitors like the Lenovo ThinkPad X240 and the HP EliteBook 820 G1. Therefore, it won our Best Value Award in December 2014.

As one of the first notebooks ever, the so to speak grandfather of the current ThinkPad X240, the X220, integrated a matte IPS display. The combination of good brightness, rich colors, generous viewing angles and ergonomic display surface often resulted in a big advantage when you compared devices. Two generations later, the grandchild still competes with the rivals. The package: 12.5-inch display, matte Full HD IPS panel, thin chassis, high quality input devices. This does not only sound like a good device for frequent travelers with high requirements in terms of security, service and support, the ThinkPad X240 was convincing in many sections of our review as well. There are also optional touch displays and you can choose between HD and Full HD resolution with a matte surface.

The ultra-mobile version of the EliteBook 840 is called EliteBook Folio 1040 G1. The device cannot only surpass the mobility of its sibling, the price is much higher as well. However, HP offers quite a lot in return: For example the high-quality 14-inch IPS display with a matte surface and Full HD resolution. The aluminum case is on a similarly high level as the input devices. Low emissions in combination with compact dimensions and a weight of just 1.5 kilograms are good features for the mobile user.

The times of bulky and inconvenient business notebooks finally seem to be over. This is the only explanation for the fact that a standard 14-inch business notebook from Lenovo, the ThinkPad T440, meets the ultrabook requirements. And is does it pretty well, so the notebook can take a spot in our Top 10. Similar to the slimmer sibling T440s, the ThinkPad T440 is available in many different configurations, including one with an HD+ (1600x900) touch display with a matte surface.

Dell's XPS 13-9333 tries to manage the balancing act between business and consumer, at least Dell sees its 13-inch made of aluminum and carbon in the backpack of wealthy students and on desks of traveling business customers. The integrated Full HD touch panel uses a glossy surface, which is typical for consumer devices. But according to Dell, this is no problem for business customers, either. Regardless of the surface, our measurements revealed a very bright display (up to 460 nits!), which can also convince in terms of color presentation and contrast. The thin case, an overall weight of 1.4 kilograms and battery runtimes of around 8 hours round off the attractive package.

Variable keys: Lenovo ThinkPad X1 Carbon Touch
Variable keys: Lenovo ThinkPad X1 Carbon Touch

9th

The Carbon model from 2014 from Lenovo courageously implements a new keyboard design, which replaces the F1 to F12 keys as well as the Fn key by a variable touch bar. Traditional ThinkPad user do not like this. However, those who are a little open to new solutions, will profit from it. Otherwise, especially the display improved compared to the predecessor. The dull TN display (relatively narrow viewing angles) was replaced by an IPS touch panel (anti-reflective) with a resolution of 2560 x 1440 pixels. In addition, the battery life got slightly longer due to the more frugal Haswell CPU. Lenovo also added ports. HDMI and Ethernet are now available via dongle. All in all, we reviewed an X1 Carbon from 2014, which eliminated the weaknesses of the predecessor (86%), which is worth being considered.

Keeps up appearances: Fujitsu Lifebook U574
Keeps up appearances: Fujitsu Lifebook U574

10th

Fujitsu's Lifebook U574 turns out to be a good looking sham. The 13 inch ultrabook has a matte touch panel. Unfortunately the TN technology is used and so the viewing angles are poor. Low brightness, very poor contrast, and poor colors are not appropriate for a price of 900 Euro. The pretty, elegant, yet yielding chassis is another weakness. So, the Lifebook U574 does not stand a chance against its competitors (for example the cheaper ASUSPRO Essential PU301LA-RO064G) with its price. Nevertheless it slid into our Top 10 due to too few competitors in the last 10 months.
