At the beginning of 2011 Intel initiated a new class of notebooks, the Ultrabooks. Notebook manufacturers could use the protected designation "Ultrabook" if they met certain criteria, for example the CPU (Intel Haswell ULV), battery runtime (6 hours FHD playback) and dimensions (<21 mm/~0.86 in). Therefore, this notebook class consists of mainly highly mobile devices with slim cases and yet decent 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, in which case there are also configurations with an optional touchscreen. Since there could be different ratings with optional touchscreens, the corresponding devices are marked accordingly.

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

Editors' Comments

Currently touch panels are being more often used in convertibles. That is, many of the slim subnotebooks of the previous months are not available as touch variants.

1st

More compact is hardly possible: Lenovo ThinkPad X1 Carbon 2017
More compact is hardly possible: Lenovo ThinkPad X1 Carbon 2017

While it previously came 2nd, the Core i5 version of the ThinkPad X1 Carbon took the lead now. Lenovo has also revised the compact ThinkPad X1 Carbon this year. The new case has an even smaller footprint and still houses a 14-inch display. Currently, the decent Full HD display is the only option. The high-resolution WQHD variant will probably be available from mid-year.

In contrast to the Core i7 model (90%), the X1 Carbon with Core i5 processor convinces with a significantly quieter fan. The supposedly slower Core i5 performs only slightly worse under load. If 8 GB of RAM are enough for you, there are few reasons justifying the extra costs of the Core i7.

Both models have the decent Full HD IPS display, good connectivity, and excellent input devices in common.

Since August, the high-resolution WQHD variant is available too (see review). The display appeared very good to us. It is also available for the Core i5 variant, which is the ideal configuration of the ThinkPad X1 Carbon in our opinion (if 8 GB RAM are sufficient).

Superslim: HP EliteBook Folio G1
Superslim: HP EliteBook Folio G1

With the EliteBook Folio G1 V1C37EA (see review), HP has created a slim, passively cooled business subnotebook, which is great for productive work. Hence, the EliteBook Folio G1 can achieve the rare "Very Good" rating. The tester praised its keyboard, its display with strong colors, and system performance after two weeks of productive use. The latter might be surprising, since passively cooled Core m CPUs used to throttle more or less heavily up to now, which means that the clock rate of the SoC falls significantly during prolonged load. Although this is also true for the EliteBook Folio G1, it is only during prolonged load and not during short load peaks. It is fun to work with the Full HD panel. While it is not extraordinarily bright, it delivers a contrast of just over 1.000:1.

The HP EliteBook Folio G1 is a very good device, but you should be aware of its limitations. If you are looking for an extremely mobile device and do not want to give up silent operation and a great keyboard, there is no reason why you should not get this notebook.

Not everybody will like the high price. Furthermore, the device that is priced at  about 1500 Euros (~$1678) also has some disadvantages: The connectivity is very limited and there is not even an adapter to USB-A included. The hinge is not stiff enough, and the ClickPad has some problems with inputs (tapping). While competitors such as the new Dell Latitude 12 E7270 are significantly heavier, they feature a standard 15-watt chip and definitely more interfaces. If these aspects and the maintenance are important for productivity, you should consider the Latitude 12 E7270, the EliteBook 1030 G1 or the ThinkPad X260. Unfortunately, only configurations of the Dell priced 1400 Euros (~$1566) and over offer QHD+ resolution.

Familiar appearance: XPS 13 9360 QHD+ i7
Familiar appearance: XPS 13 9360 QHD+ i7

Dell's brand-new XPS 13 9360 QHD+ (here in review) with Kaby Lake-Refresh SoC can immediately secure a top spot in our Ultrabook ranking. The excellent panel of the previous model was not touched; it is bright and manages a high contrast ratio of 1170:1. A touchscreen is still optional in the end of 2017. There is unfortunately PWM on all brightness levels, even at the maximum luminance. This is caused by the CABC control (Content Adaptive Brightness Control).

We can notice performance gains thanks to Kaby Lake-Refresh, which is particularly interesting for performance users. The surface temperatures are still not uncomfortable.

The XPS 13 is once again a very strong contender in the subnotebook space for this Holiday season. The performance boost is as advertised even though we had hoped for better Turbo Boost sustainability over longer periods.

Still impressive: The flawless build quality of the metal case as well as the Infinity Edge display with the thin profile. We have the QHD+/i7-8550U model of the XPS 13 in this ranking. We also reviewed the SKU with the Intel iris Plus Graphics 640 (XPS 13 9360 FHD i7 Iris, 7560U). Both models share features like Thunderbolt/USB-C as well as NVMe-SSDs.

great combination: Dell Latitude 13 7380
great combination: Dell Latitude 13 7380

The Dell Latitude 13 7380 (here in review) is a combination of the 14-inch and 12-inch Latitude 7480 and 7280 with a big influence from the XPS 13. The design is very similar to the XPS 13, but the magnesium alloy is typical for the Latitude 7000 series. The very long battery runtime (10.5 hours) and the excellent keyboard do not have to hide behind the rivals.

It starts with the foundation laid by the consumer-grade XPS 13, yet it provides all of the business sensibilities implied by the Latitude brand.

The good temperature management with sustained performance levels besides optional LTE (SIM card), Ethernet port, and Thunderbolt 3 are indicators for a sophisticated premium subnotebook.

Our only major gripes are the moderately noticeable electronic noise/coil whine, the inaccuracy of the display out of the box, and the high price.

The XPS is obviously an alternative, but the keyboard is not quite as good, there are no dedicated mouse buttons, no Ethernet, and the standard warranty is shorter. The EliteBook 1030 G1 (P5) has a slower SoC, so the Fujitsu LifeBook U747 is a better rival. The latter has many advantages, but suffers from issues like the fan noise, speakers, and touchpad.

fanless: HP EliteBook 1030 G1
fanless: HP EliteBook 1030 G1

In the EliteBook 1030 G1-X2F03EA (see review), HP uses a fanless approach and convinces the tester with the best system performance. Furthermore, the input devices are excellent and the IPS display is bright with beautiful colors. This sounds as if it would be a thoroughly well made work device - and that is what it actually is. However, we did not like the slightly short battery life of 5 to 6 hours and the limited maintenance that much. The upcoming Full HD sibling might reach better battery runtimes. The test model uses QHD+ resolution, which usually requires more energy.

The notebook is among the best devices in terms of quality and can particularly convince with its build quality, the keyboard, and the display. The application performance is also pretty good, despite the mentioned limitations, since HP has managed a good compromise between performance and heat development thanks to clever TDP and temperature limits.

The high price of 1500 to 2000 Euros (~$1710 to ~$2237) is steep. However, comparable competitors such as the ThinkPad X260 or the Latitude 12 are not really cheap either. The latter offers better expandability and a DisplayPort, which is only available in the 1030 G1 via dock. The Acer TravelMate X3 X349-M-7261 (84%, not in the top list) is cheaper. The 14-incher, priced at just less than 1050 Euros (~$1175) features Type-C-USB and a 512 GB SSD.

Security Business: Fujitsu LifeBook U937
Security Business: Fujitsu LifeBook U937
Editors Choice Award in August 2017: LifeBook U937
Editors Choice Award in August 2017: LifeBook U937

Certainly, the LifeBook U937 from Fujitsu is expensive for 1500 Euros (~$1710), but it is also special. The special features are not the SoC or the SSD, which is almost unreasonably small in view of the price class, but the security features - Smartcard, Fingerprint and TPM 2.0 in particular.

For just under $1500, you will get a very small and probably the lightest business notebook with a lot of security features, a good battery runtime and a bright display. We would definitely recommend the U937. It only has a few minor weaknesses and performs brilliantly in many respects.

The pro list is quite long and even includes easy maintenance. Moreover, the tester praised the premium display for its brightness and high color coverage. The battery life of 10:54 hours is excellent. Only the Dell XPS 13 can keep up with the Fujitsu in this respect. Complaints are the slightly inhomogeneous brightness distribution and the small, whirring fan (under load). The complaints are small in view of the pros however. Hence, we assigned the Editor's Choice Award to the Fujitsu LifeBook U937 in August 2017.

fanless: Latitude 13 7370
fanless: Latitude 13 7370

The Dell Latitude 13 7370 (see review) is a fanless 13-incher. Unlike the MacBook 12, not only can the Latitude 13 shine in terms of mobility and emissions, but also brings considerable features. Among others, the test model came with a Full HD display with IPS technology, 8 GB of RAM and a fast PCIe SSD. However, Dell charges a high price. The base model with Core m5-6Y57 costs a steep 2200 Euros (~$2469).

The competition in this Top 10 is the 12-inch ThinkPad X260, which is offered with matte non-touch display and a glossy touchscreen. The x260 tends to be cheaper, although it delivers higher performance with the 15-watt SoC. However, only Core m5 variants of the Latitude 13 are fanless. The almost frameless display resembles the quality of the excellent XPS 13 2016. This is unfortunately also true for the disadvantages.

Dell has basically incorporated a very good panel with high brightness potential, which, however, is not always available due to automatic brightness and contrast control.

The Latitude 13 7370 impresses with flawless build quality, excellent stability, and crisp input devices. The performance of the Core m platform is appropriately scaled: The 13-incher copes just as well with short load peaks as competitors with active cooling. The clock rates first fall noticeably during permanent load, which should rarely occur during everyday office use.

Larger display: Toshiba Tecra X40-D
Larger display: Toshiba Tecra X40-D

Toshiba fights the seemingly invulnerable business elite from Dell, HP, and Lenovo once again. Devices such as the X30 (see review) and the X20W (see review) impress us very much, and the new Tecra X40-D (see review) does so, too. If the X30 (13.3 inches) is too small for you, you will get a larger display in the X40 (14 inches). While it is not extraordinarily bright, and its color space is small, the touch panel with matte surface is a must have for work.

It does not quite reach the level of the excellent Lenovo X1 Carbon, but it comes close enough that the tradeoffs may be worth the lower cost.

Toshiba scores points with a relatively attractive price from 1500 Euros. Competitors such as the ThinkPad X1 Carbon, the EliteBook 1030 G1, or the Latitude 13 7370 cost significantly more or come with a significantly weaker Core m. The Tecra X40-D features a 15-watt Kaby Lake processor. In combination with the lightning fast NVMe SSD, it brings tremendous performance. However, there are also disadvantages. The modest display is only one of them.

The noisy keys are distracting, and the space bar developed a nasty habit of squeaking when pressed during our testing period.

The similarly expensive LifeBook U937 (5th place) could be an alternative you might like. It is lighter, thinner and brings a plethora of security options (smart card reader + fingerprint reader + TPM 2.0). The U937's display and keyboard are better. In return, it only comes with a SATA III SSD. If 13 inches are sufficient, you can consider the Toshiba Portègè X30-D (88%), which achieved a very good rating in our test. It is thin and light (1040 grams) and features Thunderbolt 3 and a good display.

Business: Fujitsu LifeBook U747
Business: Fujitsu LifeBook U747

Fujitsu's LifeBook U747 (see review) is a classic 14-inch business laptop with high connectivity. The IPS panel is also optionally offered as a touch screen.

It offers a superb screen, good battery life and a keyboard that allows comfortable typing. The casing is stable, well built, and its design matches well to the business claim.

Unfortunately, Fujitsu has blundered with the touchpad. It works imprecisely and the buttons appear cheap and clattery. In addition, the speakers are suboptimal and the webcam is poor. Nevertheless, the LifeBook can beat the ThinkPad T470, the EliteBook 840 G4 and the Latitude 7470.

Chameleon: Blade Stealth QHD i7-8550U
Chameleon: Blade Stealth QHD i7-8550U

Razer's Blade Stealth QHD i7-8550U (here in review) pushes the 2017 Apple MacBook Air 13 1.8 GHz (here in review) out of this ranking. Not a big surprise with the 1440x900 TN panel, which is juts outdated. Instead of a 2015 Broadwell CPU, the Razer uses a brand-new Core i7-8550U (Kaby Lake Refresh) with four native cores. 

"Laptop during the day, desktop at night." Razer was aware of the necessary balancing act between two different groups of buyers. The Blade Stealth surely is interesting in combination with the Razer Core V2 for gamers at night.

The 13-inch model is obviously not a gamer on its own; the UHD Graphics is just not powerful enough. Still, it can be intriguing to use a subnotebook at day, and just attach the external GPU in the Core V2 at home. However, all of this has a steep price: The set with the Core V2 quickly surpasses 2200 Euros, and this does not even include the desktop GPU.

Razer equips the Blade Stealth with HDMI and Thunderbolt 3, but also waives a card reader. The bright panel with good contrast and wide color gamut (easy to calibrate) is excellent. You also get accessible internal as well as the sRGB Razer Chroma keyboard.
