HP Spectre x360 15 (Core i7-8750H, GTX 1050 Ti Max-Q, 2 TB SSD, 4K) Convertible Review

Sascha Mölck, 👁 Sebastian Jentsch (translated by Alex Alderson), 03/12/2019

Six cores with stamina. The new HP Spectre x360 is an all-rounder that gets most things right. The convertible scores highly for its powerful hardware, backlit keyboard, two Thunderbolt 3 ports, good battery life and its 2 TB SSD. The touchscreen supports the HP Tilt Pen too, which adds more functionality than many 15-inch convertibles have.

HP has refreshed its Spectre x360 15 once again and equips the device with a hexa-core Intel Coffee Lake along with an NVIDIA GeForce GTX 1050 Ti Max-Q GPU, which are both considerably more powerful than the Core i7-8550U and GeForce MX150 found in the Spectre x360 15 2018.

The new Spectre x360 15 also sports a redesigned case, which has more angular corners than its predecessor. Our review unit is the 15-df0126ng to be precise and is the seventh revision of the Spectre x360 15 that HP has released in the last three years. The 15-df0126ng succeeds the following:

We have chosen to compare the Spectre x360 15 against other comparably priced 15-inch convertibles. Our comparison devices will include the ASUS ZenBook Flip 15 UX561UD, Acer Spin 5 SP515-51GN and Lenovo Yoga 730-15IKB. We shall also consider our review unit against 15-inch laptops such as the Core i7-8750H version of the Dell XPS 15 9570.

Case

The Spectre x360 15 has an all-aluminium case like its predecessors, while it retains the dark grey and gold colour scheme of last year’s models, the former of which HP still markets as Dark Ash Silver. The case looks even more striking than last year’s design with its angular and bevelled edges that run along its entire frame. HP has also placed the power button and one USB Type-C port on the back corners of the device, which should make these ports more accessible when using the Spectre in presentation or tent mode. It is worth pointing out that the device lacks a maintenance cover like many businesses 15-inch laptops have, but this is also the case for its predecessors.

Our review unit is well-built and has evenly tight gaps between materials. The aluminium shell is stable too, although we could twist the base unit and display lid a bit. That being said, the latter is sturdier than the former, but we can get the screen to deform by applying pressure to the centre of the lid. The hinges hold the display firmly in position too and are sufficiently balanced to allow for the display to be opened with one hand.

Our review unit weighs 2.2 kg (~4.85 lb), which is marginally heavier than its predecessor, although the two devices have an almost identical footprint. The Spectre x360 15 2018 is 2 mm (~0.08 in) narrower than its successor, but they are both 250 mm (~9.8 in) long and 19.3 mm (~0.75 in) thick. Our review unit is roughly as large as the ASUS ZenBook Flip 5 UX561UD and Lenovo Yoga 730-15IKB, while it is noticeably larger than the XPS 15 9570. By contrast, the Acer Spin 5 SP515-51GN is visibly bulkier at 381.5 mm x 258.1 mm (~15 x ~10 in), although it is 1.4 mm (~0.05 in) thinner than our review unit.

Connectivity

The Spectre x360 only has a few ports for a 15-inch laptop. The convertible has just one USB Type-A port, which operates at the USB 3.1 Gen 2 standard. There are two Thunderbolt 3 ports though both of which support both USB Power Delivery (PD) 3.0 and DisplayPort 1.4. The Spectre x360 15 has a HDMI 2.0a port too, which essentially gives the convertible three video outputs.

SD Card Reader

HP has equipped the Spectre x360 15 with a microSD card reader rather than the full-sized SD card reader with which it equipped previous models. While the reader in our review unit does not achieve as high transfer speeds as its predecessors, it is one of the fastest microSD card readers we have ever tested. Our review unit achieved a maximum of 193.8 MB/s when copying large blocks of data and averaged 149.3 MB/s in our JPG copying test, during which we transfer 250 JPG files that are around 5 MB each. We tested our review unit with a Toshiba Exceria Pro M501 64 GB microSDXC card, for reference.

Communication

HP has also equipped our review unit with an Intel Wireless-AC 9560 module, which supports all modern Wi-Fi standards up to IEEE 802.11 ac and offers Bluetooth 5 functionality. The Spectre x360 15 impressed in our iperf3 Client Wi-Fi tests, which we conducted under optimal conditions with our review unit next to our router and no other Wi-Fi connected devices nearby. The Spectre x360 15 does not have an Ethernet port, but you could use a corresponding USB adapter should you need a wired internet connection.

Webcam

The Spectre x360 15 has a 2.1 MP webcam that can take photos or record videos in up to 1,920 x 1,080 pixels. The results are a bit dark for our liking and are dominated by image noise. The camera is good enough for making video calls though and can be turned off with a switch on the right-hand side of the frame, the inclusion of which is rather novel.

Accessories

HP includes a carry case in the box along with the accessories that typically come with a laptop such as a charger, warranty information and a quick start guide.

Maintenance

The Spectre x360 15 has no maintenance cover as we mentioned earlier, so the bottom cover must be removed to access the device’s internal components. HP hides most screws beneath two rubber strips as it does with many of its Spectre and Envy devices.

We suggest taking care to remove these, as the plastic and adhesive layers connected to the rubber strips are easy to separate from each other. HP also secures the bottom plate to the frame with fragile plastic hooks.

We chose not to disassemble our review unit because of the likelihood of breaking it and the difficulty of sourcing replacement parts.

Warranty

The Spectre x360 15 comes with a two-year limited warranty, which includes a pick-up and return service. HP also sells its Care Pack package for €80 (~$90), which extends the warranty to three years and includes telephone support along with the coverage that is afforded in the standard two-year warranty.

Please see our Guarantees, Return Policies and Warranties FAQ for country-specific information.

Input Devices

Keyboard

The Spectre x360 15 has a backlit keyboard and number pad. The keys are flat with a smooth finish and have a short stroke with a clear pressure point. We found the keyboard easy to type on during our tests and at no point did the case bow or buckle under the pressure of our hands. The backlight can be adjusted with the F5 key and cycled between two brightness levels. In short, the Spectre x360 15 has a decent keyboard that should be good enough for most typists, although the inclusion of half-sized up and down arrows seems unnecessary considering how large the keyboard deck is.

Trackpad

HP has equipped the device with a multi-touch trackpad that measures about 12 x 6 cm (~4.7 x ~2.4 in), which is the same size as the one in the Spectre x360 13t. The trackpad is big enough on which to perform multi-finger gestures, but an even larger one would have been a better use of space in our opinion. The trackpad in our review unit responds precisely even into its corners, while its smooth finish makes it easy to slide fingers across its surface. The integrated mouse buttons have short strokes and clear pressure points too.

Touchscreen

The Spectre x360 15 has a 10-point multitouch display that reliably reproduced our inputs accurately and quickly throughout our tests. The touchscreen also works with the HP Tilt Pen, which the company sells separately. The omission to include the pen in the box is rather odd considering that HP includes it with the smaller Spectre x360 13t.

Display

The Spectre x360 15 has a 15.6-inch display that operates natively at 3,840x2,160. Our review unit achieved an average maximum brightness of 310 cd/m² according to X-Rite i1Pro 2, which is on par with most of our comparison devices but is darker than the displays with which HP equipped its predecessors and the one in the XPS 15 9570. Moreover, our review unit has a comparatively high black value, which results in a disappointing 892:1 contrast ratio. We would expect devices at this price to achieve at least 300 cd/m² and have a 1,000:1 contrast ratio, so the Spectre x360 15 falls just short here. The Spectre x360 15 does not use pulse-width modulation (PWM) to regulate display brightness, which should ensure that most people do not get eye strain or headaches when looking at the screen for a prolonged period or at night.

* ... smaller is better

Our review unit has decent colour accuracy out of the box that is on par with our comparison devices. We measured a Delta E 2000 colour deviation of 4.03 upon delivery, which is marginally higher than the ideal value of 3. The display does not suffer from a blue tint either that plagues many laptops and smartphones.

Additional calibration can improve the colour accuracy of the display, the ICC profile for which we have included in the box above our comparison table. The Delta E 2000 colour deviation drops to 1.96, while grey tones look more balanced than they did pre-calibration. Please note our ICC profile will only improve the colour accuracy of display’s that are the same model as the one in our review unit. You can set your device to the default colour profile if our calibrated one does not work as expected.

Our review unit achieved 61% AdobeRGB and 94% sRGB colour space coverages in our tests, which is better than all but the XPS 15 9570 and ZenBook Flip 15 UX561UD of our comparison devices.

The Spectre x360 15 has stable viewing angles thanks to its IPS panel. Hence, the screen should remain readable from almost any position.

However, we found the device difficult to use outdoors because of its low maximum brightness and contrast ratio. Moreover, the display has a glossy, highly reflective finish. In short, the Spectre x360 15 is designed to be used indoors or in a shady spot, where possible.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9361 (minimum: 43 - maximum: 142900) Hz was measured.

Performance

The Spectre x360 15 should provide enough processing power for all common applications and programs, while the dedicated GPU is powerful enough for some light gaming. Our test device currently costs between €2,500 and €2,600 (~$2830 - ~$2940), but there are cheaper configurations available with prices starting at around €1,800 (~$2036).

Please note that HP equips the entry-level model with a Core i7-8565U processor and a GeForce MX150 GPU, which is more comparable to the components with which HP equipped last year’s Spectre x360 15. Both components are considerably weaker than the Core i7-8750H and GeForce GTX 1050 Ti Max-Q in our review unit.

Processor

The Core i7-8750H is a hexa-core CPU from Intel’s Coffee Lake generation. The processor has a thermal design power (TDP) of 45 W and a base clock of 2.2 GHz. The Core i7-8750H supports Intel Turbo Boost, which allows it to boost to 3.9 GHz across all cores, 4 GHz on four cores and 4.1 GHz on one or two cores.

The CPU in our review unit operates at between 2.6 and 3.9 GHz during a Cinebench R15 multi-thread benchmark, which increases to between 3.9 and 4.1 GHz in the single-threaded equivalent. However, the CPU throttles to between 1.8 and 2.5 GHz in the former and 1.4 to 1.8 GHz in the latter when running on battery. These are all expected speeds for the Core i7-8750H though.

We subjected our review unit to a looped CB R15 multi-threaded benchmark that we ran for about 30 minutes to determine how it manages its performance under sustained load. The Spectre x360 15 initially scored 1,083 points, which is much higher than its Core i7-8550U and Core i7-8705G equipped predecessors along with many of our comparison devices. Benchmark scores then drop to 1,048 points in the second run through and to a low of 1,020 points three times during the loop. The CPU utilises turbo clock speeds throughout, which is impressive.

By contrast, the XPS 15 9570 initially scored 1,220 points with the same CPU but eventually thermal throttled to a minimum of 980 points. Undervolting helped the XPS 15 9570 achieve consistently higher scores though, so you may have the same success with the Spectre x360 15. We would urge researching the benefits and risks of undervolting thoroughly before attempting to do so.

Storage Devices

HP has equipped our review unit with a 2 TB Toshiba XG5-P KXG50PNV2T04, which it also used in the Spectre x360 15-ch000. The M.2 2280 SSD utilises the NVMe protocol and four lanes of PCI Express 3.0 to deliver significantly higher transfer speeds than a SATA III.

However, our review unit achieved considerably slower 4K Q32T1 speeds in CrystalDiskMark 5.2 / 6 than the Spectre x360 15-ch000. This could be firmware related though as they are equipped with the same drive. Overall, HP has equipped the Spectre x360 15 with a fast SSD, but there are better drives out there.

Graphics Card

The GeForce GTX 1050 Ti Max-Q is a more power efficient version of the regular GeForce GTX 1050 Ti, which is designed for slim and light devices. The GPU supports DirectX 12 and operates at between 1,291 and 1,418 MHz. The GeForce GTX 1050 Ti Max-Q has 4 GB of GDDR5 VRAM and can also be found in laptops such as the XPS 15 9570. Our review unit achieved 3DMark benchmark results that were consistent with a device equipped with a GeForce GTX 1050 Ti Max-Q GPU.

The Spectre x360 15 also supports NVIDIA Optimus, which allows it to switch between the GeForce GTX 1050 Ti Max-Q and the integrated Intel UHD Graphics 630 depending on the program that is running. Our review unit uses the Intel GPU when running on battery to help it save power. Likewise, the system switches to the NVIDIA GPU if it is running a game or a complex GPU-related task.

Gaming Performance

The Spectre x360 15 will play most modern triple-A games smoothly even at maximum graphics in 1080p. Some games such as "Anthem" or "Final Fantasy XV" are too much for the GeForce GTX 1050 Ti Max-Q, but they are still playable at medium graphics. Likewise, our review unit can only play a few games smoothly in 4K.

In short, you should have no problems with gaming on the Spectre x360 15.

We also checked how well our review unit could maintain its performance over time by running "The Witcher 3" for about 60 minutes. We set the game to 1080p and maximum graphics, during which it averaged 44.2 FPS, which is approximately 8% better than the Spectre x360 15-ch000 managed. We noticed no throttling with our review unit during this test, but it is worth noting that the XPS 15 9570 averaged 9% higher framerates with the same hardware.
