Toshiba Tecra X40-D (i7-7600U, FHD) Laptop Review

Carbon Copy. Toshiba's new Tecra X40-D is the Japanese manufacturer's latest entry in the thin-and-light business market and carries over several features from its smaller brother, the Portégé X30. Is the X40 able to differentiate itself enough, or is it more of the same in a larger package?

The business notebook market is a tough one in which to compete. Champions like Lenovo, Dell, and HP have long ruled the kingdom, and smaller companies seeking to usurp their thrones have failed. But that doesn't necessarily mean other manufacturers offer worse alternatives. Toshiba, for one, continues to impress with their business lines every year. We recently reviewed both the X30 and X20W from Toshiba's Portégé line. We were impressed with both devices and concluded that both were viable alternatives to their respective crowds (the X30 for road warriors and the X20W for those in search of a convertible). However, some users will find the screens of these devices don't offer enough screen real estate. That's where the Tecra X40-D comes in.

The Tecra X40 is Toshiba's latest 14-inch notebook. Designed for business users, the X40 shares a lot in common with its smaller brothers, particularly the Portégé X30. The device is a good blend of mobility and usability, owed in large part to its dual Thunderbolt 3-enabled USB Type-C ports. The higher bandwidth of Thunderbolt 3 allows for a staggering variety of options for external displays, peripherals, storage drives, and more. Combine that with its small size, lightweight frame, and stellar build quality, and the Tecra X40 makes a compelling offering. Join us as we dive into the largest of Toshiba's recent releases.

For comparison, we have selected a sample of similar competing devices. These include the 2017 X1 Carbon, X270, and T470s ThinkPads from Lenovo; the Spectre 13 from HP; and Dell's XPS 13 (equipped with Iris graphics). We will also refer to the Portégé X30-D from our June review to see what changes the X40 may offer aside from the increased screen real estate.

Case

The X40's magnesium alloy case is virtually identical to the Portégé X30, save for the increased size. That's a good thing; the X40 shares the same impressive durability as the smaller Portégé, despite its relatively thin-and-light design. The color is also the same, and it is just as striking. The underlying cobalt hue of the "Onyx Blue" color, coupled with the brushed finished and subtle sparkles, makes for a gorgeous device. The X40 stands out among other business notebooks without any garish adornments. It's a subtle, yet commanding, chassis.

The case is well designed. There is no flex anywhere across the keyboard deck or underside of the main body. Gaps are even and tight, and the chassis stands up to torsion with no unpleasant creaking. The device also bears a MIL-STD-810G durability rating. Unfortunately, the thin lid suffers the same weakness as the X30; the screen can be twisted with minimal effort. The hinge is well-tuned and can be opened with a single finger. 

The X40 is in line with other mobile business-centric ultrabooks; the case is thin (17 mm) and light (1.25 kg). It's not quite as thin as its 1 kg brother or the 1.1 kg ThinkPad X1 Carbon, but the difference is not noticeable in real-world use. The X40 has a satisfying and reassuring heft to it while still feeling nimble and light enough to carry around all day. The chassis is easy to carry but feels robust and durable. 

The overall size is almost identical to the Lenovo T470s. If users need a smaller notebook, the aforementioned X1 Carbon has a slightly smaller footprint. To most, this won't be noticeable, but it could be the difference in using the notebook during a flight.

Connectivity

The case isn't the only carryover from the X30. The port layout of the X40 is the exact same as the smaller device's. On the left, users will find a Kensington lock, a USB 3.1 Type-A (5 Gbps) port, and a combo headphone/microphone jack. On the right side lies a microSD card slot, two USB Type-C ports, and an HDMI 1.4 port. The dual USB Type-C ports support Thunderbolt 3, which allows for a broad array of peripherals. Port expansion can easily be made via a Thunderbolt 3 hub (Toshiba also sells one for their Portégé and Tecra lines). Charging and power are provided by either of these USB Type-C ports. The Smart Card reader will also be a welcome addition for some businesses as an added security measure.

SD Card Reader

The mircoSD card reader offers adequate speeds. Read speeds just south of 90 MB/s are good, but not spectacular. The reader will be more than fast enough for most users needs. Keep in mind that this reader only accepts smaller microSD cards, no full-sized SD cards like its competitors. A microSD card sits flush with the case when inserted.

Communication

Like the card reader, the Intel 8265 dual-band wireless card offers speeds that will be more than fast enough for most users. We measure a transmit rate of 528 MBit/s and a receive rate of 638 MBit/s. This places the X40 above average and in line with its competitors.

Security

As a business-oriented notebook, the X40 offers excellent security features. There is a fingerprint sensor and an Iris scanner that work with Windows Hello for fast and secure logins. The iris scanner is particularly excellent; logging in takes less than a second once the computer is woken from sleep. The fingerprint sensor is also accurate and reads fingerprints quickly, even at odd angles.

On the software side, the X40 is equipped with Intel's vPro and AMT technologies, as well as TPM v2.0, for added security. There is also a Smart Card Reader, which will be useful for some organizations and users.

Maintenance & Warranty

Maintenance is easy. After removing 12 screws (one of which is hidden underneath the rubber foot in the center), the bottom panel can be removed with minimal effort. Once inside the machine, users will have access to the RAM, battery, CPU fan, and wireless card. The SSD is not easily accessible.

Toshiba offers a standard 3-year limited warranty (1-year for the battery) with the X40. 

Input Devices

Keyboard

The keyboard is a carbon copy of the one found on the X30, and it suffers the same problems as a result. The shorter travel distance and spongy feedback may be distracting to some. The keyboard also produces an audible clack during typing that can be heard over normal office noise. The half-size Shift key on the right side will also be annoying to some typists, especially those with longer fingers. The confusing layout of the special keys is a continued hindrance.

On the positive side, the white keyboard backlight is even and bright, but not bright enough to cause eyestrain in dark environments. The keys are also well-spaced. Overall, the keyboard is average; it's perfectly usable, and most will find it acceptable.

Touchpad & TrackPoint

Touchpad and TrackPoint are also the same as those found on the X30. This is excellent in the case of the touchpad. The smooth surface is responsive and easy to navigate, and the touchpad is accurate. The TrackPoint, unfortunately, carries the same weaknesses as the X30. It's serviceable but lacks the polish of other manufacturers' TrackPoints, most notably those on the ThinkPad line. The X40's TrackPoint also feels loose in its housing, which does not inspire confidence.

The dedicated right- and left-click buttons are a vast improvement over those found on the smaller X30. Clicking is responsive, and the buttons offer firm, well-defined feedback. 

Touchscreen 

The 10-point multitouch touchscreen is excellent. Input is accurate and quick. Input tracking has a small amount of lag with longer swipes, but the touch screen is highly responsive in everyday use. It should be noted that Toshiba is one of the few notebook manufacturers to offer a touch-enabled display with a matte finish. 

Display

Subpixel array
Subpixel array

The 14-inch 1920x1080 matte display is fairly good. Toshiba currently only offers this touch-enabled FHD option. While a 2560x1440 option might sound nice, the benefits of a higher resolution at this screen size would be marginal at best compared to the trade offs in battery life and graphical performance. 

One of the display's weaknesses is its mediocre average brightness, which sits at 261 cd/m2, well behind its competitors. While the screen gets bright enough for indoor use, sunlight is problematic, even under shade. Brightness distribution is also uneven. The edges of the display are noticeably dimmer than the center, which can be distracting. This is especially true when viewing full-screen movies.

* ... smaller is better

PWM is present at brightness levels up to 99%, but at over 20,000 Hz, only the most sensitive users will notice it. Contrast levels are good, and blacks are deep and inky. The color temperature is also well tuned, and whites are neutral.

Perhaps the biggest shortcoming of the display is color. Color reproduction is weak, covering only 60% of the sRGB color space and 38% of the AdobeRGB color space. Compared to the X30, color accuracy is also poor; deltas are relatively high both colors and grays. On its own merit, this isn't problematic. Colors are still more than accurate enough for office work and day-to-day tasks. Professionals that work with color will find fault with the screen, however. Calibration helps quite a bit and drops DeltaEs to 2.2 and 4.6 for grays and colors, respectively.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
26.8 ms ... rise ↗ and fall ↘ combined↗ 16.4 ms rise
↘ 10.4 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 53 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.5 ms).
       Response Time 50% Grey to 80% Grey
38 ms ... rise ↗ and fall ↘ combined↗ 19.6 ms rise
↘ 18.4 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 35 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (40.7 ms).

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 detected 20410 Hz ≤ 99 % brightness setting

The display backlight flickers at 20410 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 20410 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9813 (minimum: 43 - maximum: 142900) Hz was measured.

Owing to its IPS panel, viewing angles are good. The screen remains legible when viewed off angle, and there is no noticeable shift in color or brightness distribution.

Performance

Toshiba has equipped the Tecra X40 with some of the highest tiered ultrabook components available today. The Kaby Lake Core i7-7600U CPU from Intel puts up a powerful show. In addition, the Samsung PM961 PCIe NVMe SSD is blazing fast and goes a long way in making the system snappy and responsive. As such, the Tecra X40 is an excellent office notebook and is able to chew through any productivity tasks throw its way quickly and efficiently. Graphical processes present a challenge, mainly because of the integrated Intel HD Graphics 620. As such, gaming is a weak spot here, as it usually is with business-class notebooks.

Processor

As we stated earlier, the Intel Core i7-7600U is the fastest U-class processor currently on offer from Intel built on their Kaby Lake platform. The CPU features a base clock of 2.8 GHz with a boost up to 3.9 GHz. The two Hyperthreaded cores can power through heavy multi-core loads with aplomb and are quite competent considering the targeted use case of office work. 

Using Cinebench to test the CPU, however, we don't see much of a benefit over the lower-clocked i7 and i5 processors in other business notebooks, especially in multi-threaded tests. Some benchmarks place the X40 about 10-15% above i5-equipped notebooks, but others place it below. That said, users may notice improved performance over other devices equipped with a Core i5, but the improvements are meager. 

Long-term stability shouldn't be a concern. Running Cinebench R15 multiple times in a row show that the system can consistently push through demanding tasks without a hitch.

System Performance

Overall system performance is, again, excellent. Apps open quickly, tasks are responsive, and the overall experience is very snappy. The combo of the i7-7600U and Samsung NVMe SSD are largely responsible here, as is the generous 16 GB of DDR4 RAM (which can be upgraded to 32 GB).

Using PCMark 8 to test performance, the X40 is in line with competitors. Other notebooks in this class are generally very responsive, especially those with NVMe drives. As such, there's nothing to really set the X40 apart here. This system performs well, but so do many other manufacturers'.

GPU Performance

The integrated Intel HD Graphics 620 GPU is a common feature on most office and home notebooks. While competent enough for day-to-day use, the GPU isn't powerful enough for even moderately demanding 3D applications. Our review unit scores 1088 in Fire Strike, which is near the top of its competitors. The Iris Plus Graphics 640 in the Dell XPS 13 offers about 25-30% better performance. When compared to dedicated GPUs, graphical performance is anemic; even entry level cards like the NVIDIA GeForce 940MX or GeForce MX150.

Gaming Performance

Echoing the weak graphical performance, gaming performance leaves a lot to be desired. AAA titles are out of reach for the X40, and older or less demanding titles will need to be turned down to lower resolutions and settings. Lighter Indie games like Stardew Valley and Minecraft run well enough. Road warriors hoping to pass the time with a game or two between meetings will want to find something with at least a low-powered dedicated GPU like the aforementioned NVIDIA GeForce MX150.

Stress Test

Using synthetic tools like Prime95 and FurMark, we see how to system performs under full stress. The Tecra X40 is fairly conservative when under full load. While running Prime95, the Core i7-7600U boost up to its maximum clock speed of 3.9 GHz, but cannot hold at that level, settling in at about 3.0 GHz. Temperatures spike to 85º C before ramping back down to about 75º C. There's plenty of thermal headroom here, so it is interesting that the X40 plays it rather safe.

FurMark proves to be a challenge for the system. The CPU is throttled back to a mere 1.5 GHz to allow the GPU to hit 900 MHz while keeping temperatures in check. Heat is well managed and averages just under 70º C. Running FurMark and Prime95 together see the CPU average at 2.2 GHz and the GPU at 650 MHz. Neither component hits its full potential during this test, but this is likely to keep heat exhaust down. Temperatures spike to 81º C before falling back to the mid-60s. Again, there is plenty of thermal headroom here, but given the lower powered ultrabook chip, this performance is not unexpected.Intel Core i7-7600U Laptop Processor

Emissions

System Noise

Fan Noise profile
Fan Noise profile

The Tecra X40 is fairly quiet. The fan cannot be heard during simple tasks and only ramps up to 40 dB(A) under the most extreme of tasks. Under load (running 3DMark 06), system noise averages at about 33 dB(A). Thankfully, the fan emits a low-pitched whir that can barely be heard above normal ambient noise (such as in an office). Toshiba has done a good job with the engineering behind the fan; both the Tecra X40 and the Portègè X30 are quieter than the competition. The fan will not be a distraction with this machine. There is no coil whine present as well.

Temperature

Heat management is another high point for the X40. Even under the unrealistic synthetic stress of our test suite, the device only reaches 43º C at the exhaust vents in the center of the back of the chassis. The keyboard and touchpad remain cool to the touch and never become uncomfortable to use. Users will be able to hold the notebook in their lap comfortably no matter their workload.

Speakers

Speaker profile
Speaker profile

The speakers are typical for a thin-and-light laptop with minimal bass and pronounced highs. The overall sound is thin and tinny and not very pleasant. The speakers are fine for video calls and casual media consumption, but audiophiles and music lovers won't find a lot to like. The speakers get reasonably loud at 77 dB and remain clear at their maximum volume. Thanks to the tight construction of the device, there's no rattling or unwarranted noise due to the speakers.

Energy Management

Power Consumption

Thanks to its low-powered ultrabook components, the X40 doesn't draw much power at all. Under load, the machine pulls about 25 Watts from the wall on average. At its most demanding, the X40 only pulls about 30 Watts. The included 45 Watt power adapter can easily provide all the power the notebook could want and then some. The device can be charged through either of the USB Type-C ports.

Battery Life

The 48 Wh battery offers shorter run times compared to the competition, which is a bit surprising. Using our Wifi v1.3 test (Balanced power setting, screen set to 150 nits, loading a new web page every 30-40 seconds), the X40 lasted just shy of 6 hours; compared to the 7+ hours of the Portègè X30 and the 9 hours of the Lenovo ThinkPad X1 Carbon (2017), this is a bit disappointing. The X40 will almost get through a full workday, but users should carry the charger to top off when possible.

Verdict

In review: Toshiba Tecra X40-D. Review model courtesy of Toshiba.
In review: Toshiba Tecra X40-D. Review model courtesy of Toshiba.

The Toshiba Tecra X40 is essentially the Portègè X30 with a 14-inch display. As such, it shares many of the same strengths and weaknesses of its smaller brother. The beautiful chassis is well engineered and very sturdy while remaining fairly light for a 14-inch notebook. The biometric sensors are quick, reliable, and easy to use. The NVMe SSD is insanely fast and goes a long way in making the system as a whole feel very responsive and snappy. Coupled with the higher-binned Core i7-7600U, the Tecra X40 is a fast office machine in a svelte, stunning body.

However, the lid flexes too much for comfort and the keyboard isn't our favorite. The noisy keys are distracting, and the space bar developed a nasty habit of squeaking when pressed during our testing period. The display also isn't as vibrant or rich as other business notebooks but is more than acceptable for everyday use.

The Toshiba Tecra X40 is a competent mid-size business notebook. It doesn't quite reach the level of the excellent Lenovo X1 Carbon, but it comes close enough that the tradeoffs may be worth the lower cost. If users don't mind sacrificing a few ports and can deal with a lower-quality keyboard, the Tecra X40 is definitely worth a look. The fact that is also several hundred dollars less than the X1 Carbon only sweetens the deal.

Sam Medley - Review Editor - @samuel_medley
I've been a "tech-head" my entire life. After graduating college with a degree in Mathematics, I worked in finance and banking a few years before taking a job as a Systems Analyst for my local school district. I started working with Notebookcheck in October of 2016 and have enjoyed writing news articles and notebook reviews. My areas of interest include the business side of technology, retro gaming, Linux, and innovative gadgets. When I'm not hunched over an electronic device or writing code for a new database, I'm either outside with my family, playing a decade-old video game, or sitting behind a drum set.
