Ultrabook

Multi-mode. Handy as a subnotebook, thin and light as a tablet. The compact form factor could currently represent the optimum between mobility and productivity. The Core M ensures long battery runtimes and the IPS panel a good picture impression. Read our review to find out why the package still cannot really convince us.

Boldly priced. Actually, HP has almost done everything right in the refresh of its premium model and presents a throughout well-designed, very slim and swift business ultrabook with an IPS touchscreen and extensive security features. However, incomprehension evolves when comparing the price-performance ratio with the competition.

Sharp as a knife. Slim, elegant and streamlined - the looks of the S7 will stop everyone from simply passing by Acer's premium range. Will the pricey first-rate configuration of WQHD screen and SSD Raid ultimately be convincing? We examined that in this in-depth test report.

Featherweight. The updated version of the Toshiba KIRA weighs 200 grams less without the touchscreen and is therefore one of the lightest 13.3-inch devices on the market. The new Broadwell hardware ensures sufficient performance and long battery runtimes, but is the high price justified?

Let the games begin! Equipped with an Nvidia GeForce 940M, the ThinkPad T450s can cope with 3D applications and games - and that for a relatively low extra charge. Thanks to a 96 Wh battery capacity, record-breaking runtimes should be possible.
Intel Core i5-5200U | NVIDIA GeForce 940M | 14.00" | 1.8 kg

Disappointing display. Fujitsu's new 14-inch business Ultrabook, the LifeBook U745, left a good impression overall. However, Fujitsu has made a mistake when selecting the display.

Expensive runtime wonder. Toshiba charges a steep price of 2000 Euros (~$2138) for the top configuration of its latest business convertible – in return the user gets a business device with comprehensive features and enormous battery runtimes. Thanks to the anti-reflective touchscreen, the Portege Z20t can also be used outdoors.

Carbon-based evolution. While Lenovo’s ThinkPad X1 Carbon series laptop has always been an impressive piece of hardware, some design decisions have polarized the audience. The X1 Carbon 3rd Gen answers the criticism with solutions which aim to please all parties. We explore the results in excruciating detail in our full review. Update 04/20/2015: Core i7 and PCIe-SSD in review!

Little jack of all trades. The manufacturer describes its new EliteBook as a sturdy travel companion. The build and emissions impress us, but compromises have to be made in performance compared with the competition.
Intel Core M-5Y51 | Intel HD Graphics 5300 | 12.50" | 1.2 kg

Simply brilliant. Dell now offers the XPS 13 with a non-touch display and a more mainstream resolution of 1920 x 1080 pixels for a much more affordable price. Not only is the new display brighter, but it's matte as well, which improves outdoor usability. The remainder of the hardware is very similar to the QHD+ version, so the new model inherits both its strengths and weaknesses.

Luxury Yoga. Lenovo brings the flexible Yoga design to the desks of business people with its ThinkPad Yoga 14. In this report, we will discover whether the Ultrabook, based on a Broadwell processor and dedicated graphics card, is well equipped for office use.

Even more pixels! As the successor to Dell's XPS 15 (Late 2013) with its QHD+ display, the American company now presents the overhauled XPS 15 in a new configuration with a 4K UHD display and a more powerful processor. The almost perfect display image and reasonably good performance are enticing. Unfortunately, some of the computer's former problems remain unresolved.

1, 2, Yoga 3. Lenovo squeezes a 14-inch screen into a chassis that's roughly the same size as last year's Yoga 2 13 and upgrades the hardware at the same time as well. The new Yoga 3 14 inherits most of the predecessor's familiar traits and while it improves in some areas, it also takes a slight step back in another.

Does an upgrade make sense? Several weeks after their official launch, most of the new Broadwell processors passed through our test course. So, it is time to deliver a first summary. How much do the CPU and graphics unit perform better than the predecessor models'? Did the battery runtimes improve, too? We know the answers!

The return of the old master. What can be improved in an almost perfect notebook? Lenovo might have thought that it is better not to change too much and launched an only slightly revised edition of the T440s with the ThinkPad T450s. At least, the manufacturer (partly) answered the complaints about the predecessor's unusual five-button ClickPad.

No compromises - part 2. Compact, highly mobile, attractive - this is how one could sum up the Dell XPS 13. Thanks to its Core i7 processor, the notebook is quite powerful as well, although the battery life suffers as a result.
Intel Core i7-5500U | Intel HD Graphics 5500 | 13.30" | 1.3 kg

Working on details. Lenovo's ThinkPad T450s steps in big shoes. The expectations are high that the successor of the overall successful T440s is even a bit better. In fact, the T450s proves to be a carefully matured perfectionist - and it now challenges the competition from HP, Dell & co.
Intel Core i7-5600U | Intel HD Graphics 5500 | 14.00" | 1.6 kg

No (big) experiments. Lenovo only introduces small changes for the latest sibling of the X200-series – but just those changes improve a good subnotebook and result in an even better one. The manufacturer even listened to the criticism about the unpopular 5-button ClickPad of the predecessor.
Intel Core i7-5600U | Intel HD Graphics 5500 | 12.50" | 1.4 kg

Slimline. How much flatter does it get? The Core M is at its best, with 12 millimeters in an airless case. The performance lags behind the Haswell competitors, and the Zenbook inspires no wonder in terms of battery life. Still, input devices, workmanship, emissions, and (last but not least) the price argue in favor of purchase.
Intel Core M-5Y10 | Intel HD Graphics 5300 | 13.30" | 1.3 kg

No more fans. Core-M makes it possible: The new ThinkPad Helix 2 is available without a fan for the first time, but is still supposed to provide sufficient performance for all important applications. Can the versatile convertible meet the high expectations of business customers?

The carbon dwarf. If you do not like a tablet, and a smartphone is not large enough, then the 12.5-inch Ultrabook Dell Latitude 12 E7250 is a full business notebook that fits in your bag. Let us see what the small device is capable of.

Refusal to compromise… You can’t have it all—or can you? Dell’s latest XPS 13 pushes the envelope in a number of different critical categories, but most notably portability: this is the smallest 13.3-inch notebook we’ve reviewed. Could we be witnessing the best ultraportable to date?
Intel Core i5-5200U | Intel HD Graphics 5500 | 13.30" | 1.3 kg

Evolution instead of revolution. The Dell Latitude is equipped with Intel's latest CPU generation Broadwell and wants to get the top spot in the business segment, currently occupied by the Lenovo ThinkPad T440s. What are the advantages of the modern 14-nm technology for the user and does the 14-inch notebook have any other highlights – we tested it.

Ultrabook Convertible. Dell’s Latitude 13 7350 is a mixture of an Ultrabook, a tablet and a convertible. The combination of silent operation, good keyboard and long battery runtimes make it a companion for business users.
Intel Core M-5Y10 | Intel HD Graphics 5300 | 13.30" | 1.7 kg

Quality for little money? Asus wants to put the competition under pressure with affordable business laptops and equips its new 14-inch flagship with the currently fastest ULV processor, plenty of working memory, and a swift SSD to accomplish that. We will reveal why it is nevertheless not enough for first place in the category.
