Notebookcheck's Top 10 Convertible Laptops

HP's EliteBook x360 1030 G3 (here in review) in a high-end convertible. The performance of the compact EliteBook x360 is not much better compared to many Ultrabooks, but the EliteBook x360 1030 G3 combines many useful features. 4G LTE and NFC are optional and many security features make it fit for business users. Thunderbolt 3 is supported as well and 4 speakers provide above-average sound quality.
We also liked the bright multi-touch display of HP EliteBook x360 1030 G3 with full sRGB gamut.

The price-performance ratio is worse compared to similar Ultrabooks, but the HP EliteBook x360 1030 G3 convinces with numerous features, which create a very good business device.

The stability of the current device is not quite as good as the slightly thicker HP EliteBook 1030 G2. The compact construction also results in slightly higher surface temperatures. The CPU boost of the Intel Core i5-8250U cannot be maintained for long periods. Other problems are the lacking card reader as well as dedicated mouse buttons.
If you can live with that, the HP EliteBook x360 G3 will provide excellent build quality. It is also very quiet under load and does not consume much power. This results in long battery runtimes thanks to the large battery.

The https://www.notebookcheck.com/Test-HP-Spectre-x360-13-i7-8550U-FHD-SSD-Laptop.280294.0.htmlHP Spectre x360 is a well-made convertible that almost made it to the very top. Case and build quality are state of the art, and the high-contrast display with its near 100% sRGB coverage is a pleasure to look at.

And let us not forget the comfortable keyboard and touchpad, USB 3.0 Type-A and Thunderbolt ports, and a microSD card reader.

The Spectre’s performance does not justify the HP Spectre’s high price. Build quality and its unique design, on the other hand, surely do.

Performance was just mediocre at best due to massive power throttling despite low overall TDP limits. This might make a difference when reading and writing emails or using the web, but power users with demands for long periods of sustained load will most certainly suffer.

Another problem was the comparatively dark, yet shockingly reflective display - a combination that made working with the device harder than we were hoping for.

We have also had the UHD SKU in review. The Spectre x360 13-ae000 (i7-8550U, 4K UHD) offers a significantly shorter battery life (7:04 hours instead of 8:47 hours) and its i7 CPU is already severely limited by the temperature-induced throttling during regular sustained load.

Equipped with a 256 GB SSD, the Spectre x360 13 can be had for around $1,500. A more affordable and better equipped alternative would be Acer’s 13-inch Acer Spin 5 (i7-8550U, FHD, 16 GB RAM, 512 GB SSD). Performance-wise these two were comparable, although we have to add that the Acer lacks a Thunderbolt port. More power and less throttling are available in the Lenovo Yoga 920-13IKB (i7-8550U, FHD) Convertible ReviewLenovo Yoga 920 (not to be found in this top 10 list).

The Dell Latitude 7390 (here in review) is a premium convertible, which is primarily designed for business users. It combines very good performance figures with the versatility of a convertible. Our test model of the Dell was equipped with the Intel Core i7-8650U, which is currently the fastest ULV-chip from Intel. We were not fully convinced by the performance though, because it is not faster than the Core i7-8550U in multi-core applications.

The Latitude 7390 2-in-1 is a robust and well-designed notebook with very good input devices and a good system performance in general. However, there are some drawbacks, and the price is high as well. A look at the competition is therefore not a bad idea.

You cannot really make any mistakes with the Dell latitude 7390 if you are looking for a convertible. We still want to mention the very glossy screen since it will affect the outdoor usability quite significantly. Still, the Latitude 7390 performed well in our review. The design is always a matter of taste, but we liked it, and the convertible also collects points for the sturdy base unit and very good input devices.

The Dell XPS 15 9575 (here in review) is supposed to expand the regular XPS 15 9560 with the advantages of a convertible. This was a success, because both the quality and the stability are on the familiar high level. Our test model is based on the Intel Core i5-8305G with the discrete AMD Radeon RX Vega M GL/870 graphics card. The combination is convincing and the performance of the AMD Radeon RX Vega M GL/870 is sitting between the GeForce GTX 1050 and GeForce GTX 1050 Ti.

This means our test sample of the Dell XPS 15 9575 is powerful enough for all modern titles, which expands the usage scenarios of the convertible even further.

Dell's new convertible introduces many new features, and almost all of them can convince us. The Kaby Lake-G usually competes with a GTX 1050 as well as a Core i7-7700HQ, but stays cooler compared to the XPS 15 9560. However, the Maglev keyboard leaves mixed impressions and the Toshiba NVMe-SSD is slower than Samsung's PM961. You should also carry a USB-C adapter; a cleaning cloth for the dark surfaces does not hurt, either.

The XPS 15 9575 is not a cheap devices, and you definitely pay a premium for the convertible features compared to conventional multimedia laptops.

The Lenovo Yoga C930 is the successor to the Lenovo Yoga 920. The case was completely revised and the placement of the speaker is still unique. Thanks to Dolby Atmos and four speakers, watching movies is very enjoyable. The 14-inch convertible is powered by an Intel Core i5-8250U, which performed well in multi-core scenarios during our review.

Lenovo unfortunately does not offer a dedicated GPU for the C930, which limits the 3D performance. This means the integrated Intel GPU takes care of all the graphics calculations.

The Lenovo Yoga C930 is a perfect working device for everyday business tasks. In addition, you can enjoy great multimedia qualities if you also want to use it for your free time. The C930 really shows its strengths during the playback of videos or music.

The Lenovo Yoga C930 is a great device. You get a convertible with solid performance figures and very good build quality. The highlight is the speaker system, which is a small sound bar inside the 360-degree hinge.

The device is shipped with an active pen, which can be stored inside the device and is charged at the same time. The display of the C930 is a minor drawback, because the average luminance of our test model could be a bit better. The quality of panel is still good with wide color gamut and the lack of PWM.

Lenovo’s Yoga 730-13IKB is a compact 13-inch convertible. The 4K touchscreen with a very good color space coverage is most certainly its highlight. Unfortunately, the highly reflective surface made it practically unusable outdoors.

The Lenovo L390 Yoga (here in review) is equipped with a fast Whiskey Lake processor. Lenovo sticks with the excellent input devices, which are great for frequent writers. The 14-inch convertible also convinces with good performance figures. The materials are sophisticated, the convertible offers fast Wi-Fi and the ActivePen Pro can be stored inside the chassis.

All in all, the Lenovo ThinkPad L390 Yoga does not offer any surprises. Very good build quality and materials meet excellent input devices, and the performance also corresponds with the price tag.

Drawbacks include the short warranty period of just 12 months and the missing WWAN option, which would have been great for a business device. The restrained fan control results in high surface temperatures under load and the limited color gamut of the display prevented a higher rating.

The HP ProBook x440 G1 is an affordable and at the same time well-equipped device. For about 1000 Euros you get a convertible with the Intel Core i5-8250U. It is a modern processor, which is also very efficient, so you get long battery runtimes.

HP offers the device with a number of different displays. Our test model convinced with a bright backlight and wide color gamut.

All in all, the HP ProBook 440 G1 offers good system performance, so it is a reliable office companion.

If you are looking for an affordable convertible, the HP ProBook x360 440 G1 convinces with good features and long battery runtimes.
