Dell Vostro 15 5568 (i7-7500U, 940MX) Laptop Review

Mike Wobker (translated by Sabrina Hartmann), 12/07/2017

New assets, old shortcomings. We already announced in January that Dell was planning to offer the Vostro 15 5568 with other processors and a dedicated graphics solution. This configuration is now available and we are going to test what this entry-level business laptop with an Intel Core i7-7500U CPU and an Nvidia GeForce 940MX can offer.

We already tested the Dell Vostro 15 5568 (i5-7200U, HD620) in January 2017. The device was able to score with a good system performance and a battery life suitable for everyday use. The data sheet at that time included the entry-level business laptop with a faster processor variant and a dedicated graphics card, but this configuration could not be ordered from Dell yet. Now we are testing the visually identical device with an Nvidia GeForce 940MX GPU and an Intel Core i7-7500U processor.

In our current tests, we are expecting benchmark results that correlate with the boost in performance. The upgraded version not only has to compete with the test model from January but also with equally equipped business rivals and a convertible which has almost identical hardware as well. We chose the HP Spectre x360 15, Lenovo's ThinkPad T570, the Acer TravelMate P658-G2 and the Huawei MateBook D for this.

Connectivity

Dell did not change the connectivity options for the Vostro 15 5568. See our Vostro 15 5568 (i5-7200U, HD620) review to get an impression of the offered ports and their performance.

SD Card Reader

The Vostro 15 5568 reached only substandard transfer rates in our previous SD card reader test. The current test model does even worse. While the lower value for copying files using our reference memory card Toshiba Exceria Pro SDXC 64 GB UHS-II could be explained away with measuring inaccuracies, the extremely bad result for reading files can only be ascribed to the SD card reader's bad performance.

Communication

Dell equipped the Vostro 15 5568 with an Intel Dual Band Wireless-AC 3165 WLAN adapter which already did not perform very well in the predecessor model. But the module reaches a new low in our current test device. The data transfer rates are absolutely outdated. Even though Intel listed on their own website that the WLAN adapter supports the 802.11ac standard, we could only find the standards a, b, and g in the device manager of our test system. We were unable to figure out the reason for this constraint. An RJ45 port is included for a cabled network connection.

Security

In comparison to our January review of the Vostro 15 5568, the evaluation of the security features remains unchanged. See our review for further details. However, our current test device is equipped with an optional fingerprint-sensor which has very fast reaction times and unlocks the device in less than one second.

Quality journalism is made possible by advertising. We show the least amount of ads whenever possible. We intentionally show more ads when an adblocker is used. Please, switch off ad blockers.

Accessories

Since our test device is equipped with a dedicated GPU, a 65-watt PSU (otherwise 45-watt) is included. There are no special accessories, but Dell does offer a few USB docking stations, external batteries, bags, and more in their store.

Maintenance

We discussed the maintenance options in detail in our previous review for the Dell Vostro 15 5568 in January, so we refer to that article again.

Warranty

Dell grants a one-year warranty for the Vostro 15 5568, including a collect & return service. It is possible to extend this warranty in a variety of ways for an additional charge. For example, an upgrade to a three-year on-site service costs about 40 Euros (~$47).

Input Devices

Our assessment of the input devices can be found in our Dell Vostro 15 5568 review from January. In short: The keyboard is unsuitable for frequent writing and the touchpad stutters during drag & drop actions. Cursor movement is no problem, though, and multi-touch gestures, such as scrolling with two fingers, are executed very well.

Display

Subpixels
Subpixels

The display in our test model is slightly different from the one used in the Dell Vostro 15 5568 from our January test. The average brightness is a bit lower, but the response times are better. None of the competitors' displays could compare to such low values.

The Full HD TN panel has a resolution of 1920x1080 pixels. Alternatively, the Vostro 15 5568 is also available with a less expensive HD TN panel (1366x768 pixels).

* ... smaller is better

The brightness and contrast of the screen are subpar, causing the screen content to appear somewhat pale and colorless. The low black level adds to this impression and the color-space coverage is substandard in comparison to other devices. Additionally, we detected PWM-flickering during our measurements. The display flickers at 26,000 Hz with a brightness setting of 20%. This is a relatively high value, but working on this screen might still prove strenuous to users with sensitive eyes.

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
15 ms ... rise ↗ and fall ↘ combined↗ 11 ms rise
↘ 4 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 11 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (26.1 ms).
       Response Time 50% Grey to 80% Grey
41 ms ... rise ↗ and fall ↘ combined↗ 24 ms rise
↘ 17 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. » 48 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41.7 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 26000 Hz ≤ 20 % brightness setting

The display backlight flickers at 26000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 26000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 10415 (minimum: 43 - maximum: 588200) Hz was measured.

Performance

The Vostro series mainly caters to business users looking for an inexpensive entry-level device. Hence, it includes low-priced models for about 500 Euros (~$588) with a Kaby Lake Core i3 processor, 4 GB DDR4 RAM and a 500 GB HDD, but it also includes higher-priced models such as our test device with a dedicated graphics card for about 800 Euros (~$941). Further hardware upgrades are available via the Dell customer service.

 

Processor

Our test device utilizes an Intel Core i7-7500U CPU. This processor stands out due to low power consumption and is suitable for a more challenging multi-tasking environment. It is possible to run even demanding 3D applications in combination with an appropriate graphics card.

The processor of the Vostro 15 5568 placed in the midrange of the comparison devices in our tests. A prolonged test revealed that the CPU is able to sustain its performance constantly. However, the performance boost is relatively small in comparison to the Vostro 15 5568 with Intel Core i5-7200U CPU. So potential customers may also want to consider the less expensive i5 CPU.

Further results of the Core i7-7500U CPU can be found on our benchmark page.

System Performance

The Vostro 15 5568's system runs smoothly in everyday use. The benchmark results confirm, however, that the advantage over the Vostro 15 5568 with an i5-7200U CPU is limited. Our test device scored only slightly higher, probably not justifying the price for the supposedly faster CPU.

Storage Devices

Dell utilized a Micron SSD with 256 GB capacity for our test device. This SSD is considerably slower than the 256 GB SanDisk X400 which was used for the configuration of the Vostro 15 5568 with an i5-7200U CPU. This is the reason why our test device scored significantly lower and ended up in the last spot of our comparison list.

Our benchmark section shows how this SSD compares to other storage devices.

Graphics Card

The Intel Core i7-7500U processor has an integrated HD Graphics 620 graphics card suitable for most office applications, basic image-editing and light 3D modeling. The actual performance of the HD Graphics 620 depends on the system's RAM, among other factors.

Additionally, our test device is equipped with a dedicated graphics card. Dell used an Nvidia GeForce 940MX with 4 GB GDDR5 RAM for the Vostro 15 5568. This is a mid-range graphics card which is only just able to display current games smoothly on lowest settings.

Our benchmark results clearly show the performance gain in comparison to the Vostro 15 5568 without dedicated GPU. However, most competitors that are also equipped with a GeForce 940MX score higher.

See our benchmark page for further comparisons of the Nvidia GeForce 940MX's performance in other devices.

Gaming Performance

Nvidia's GeForce 940MX is a solid graphics card for casual gamers or fans of older games. Even newer games ran smoothly on low settings in our gaming benchmarks. The performance even suffices for medium or high settings in older games. The test results meet the expected level, but some competitors manage to elicit a significantly higher graphics performance from the GeForce 940MX.

Find out on our benchmark page what performance to expect from Nvidia's dedicated graphics card in other games.

Emissions

System Noise

For an evaluation of the fan noise, we refer to our review of the Dell Vostro 15 5568 with Core i5-7200U CPU. The only difference is the noise under load. Due to the dedicated graphics card, a higher cooling performance is necessary. As a result, the fan noise becomes clearly audible, for example while running games. The steady buzzing is tolerable, though. Most competitors are much quieter under load, despite having dedicated GPUs.

Temperature

Stress test
Stress test

The dedicated graphics card is noticeable in regard to the temperatures as well. While idling, our test device heats up only slightly more than the model without an Nvidia GPU, but the surface temperatures rise significantly under load. They are up to 15 °C higher at some hot spots than for the Vostro 15 5569 with Intel HD Graphics 620. Nevertheless, the device can still be used on one's lap without any problems.

In our stress test scenario, the Vostro 15 5568 behaved the same way the January test model did. The core temperatures rose to over 80 °C while the processor's base frequency did not throttle, even after a full hour.

Battery Runtime

It does not come as a surprise that the Vostro 15 5568 with GeForce 940MX has a shorter battery life than its counterpart without dedicated GPU. However, we would have liked a higher stamina, especially in WLAN. In comparison to the competitors, our test device ranks lowest, well behind the devices of other manufacturers which provide significantly longer battery runtimes.

The Vostro 15 5568 is still an inexpensive business laptop. The offered performance is appropriate for the low price. The low WLAN performance and the bad keyboard in particular might discourage interested customers. Whether the minimalistic security features should be taken into regard for the purchase decision is something prospective buyers have to decide for themselves.

With the Vostro 15 5568, Dell offers a low-priced and visually pleasing business laptop. The WLAN and security features have some flaws, though.

For interested customers looking for an inexpensive business laptop, the Vostro 15 5568 is certainly still suitable. The device can run standard office applications (presentations, spreadsheet analysis, and e-mails) without any problems. However, the bad display has to be taken into account, especially for 3D applications requiring a dedicated graphics card. If the offered viewing angles and color-space coverage are sufficient, then this laptop is a valid purchase option.
