Business notebook with long runtimes. Skylake, DDR4, M.2-SSD – Dell updates its Latitude 15 E5570. You still get a very good keyboard, simple maintenance as well as a docking port, and Dell also managed to improve the battery runtimes. Show For the original German review, see here. Dell's Latitude E5000-series consists of business notebooks with a mainstream price tag. Our review unit today is a current 15.6-inch model with the designation Latitude 15 E5570. This model is primarily an update and there are just minor visual changes compared to the predecessor. Inside the notebook is a Skylake processor supported by DDR4 memory. The notebook now also offers a slot for an M.2-SSD. Rivals for the Latitude include systems like the HP EliteBook 850 G3, Lenovo ThinkPad L560, and Toshiba Tecra A50-C.

Similar to the predecessor, Dell once again uses a black plastic chassis with rounded corners and striking hinges for the Latitude 15 E5570. There are hardly any visual changes and you can immediately notice the relationship between the E5570 and E5550. The whole bottom panel of the notebook is basically the maintenance hatch. It is pretty easy to remove, but more on that later. The build quality does not reveal any weaknesses: The gaps are even, and we cannot notice any protruding edges. There is really not much to criticize in terms of stability. Only the base unit can be twisted a bit too easily for our taste, but the torsion resistance of the lid is okay. Pressure on the back of the display only creates picture distortions at some spots. The hinges keep the display well in position and there is just minor bouncing. It is possible to open the lid with one hand. The E5550 and E5570 do not differ in terms of size or weight, and the values are also on par with the rivals. The EliteBook 850 G3 is a bit lighter at almost 1.9 kg, while the ThinkPad L560 is thicker and heavier than the competition.

The ports are actually identical, but Dell slightly changed the layout. We can see a clear improvement when we look at the SIM-card slot, which can now be accessed from the outside. The memory-card reader is one of the faster models. 250 jpg pictures (~5 MB each) are transferred at 155 MB/s. We check the performance of the card reader with our reference card from Toshiba (Exceria Pro SDXC 64 GB UHS-II).

Besides the WLAN standards 802.11 a/b/g/n, the module also supports the fast ac-standard. We did not encounter any signal problems between the notebook and the router. Wired network connections are handled by a Gigabit-Ethernet chip (I219-LM), which is also provided by Intel. It works as expected. The Latitude is also available with an optional LTE modem, but our test model is not equipped with it. It is no problem to upgrade it, because the slot, the antennas, and the SIM-card slot are already implemented. The webcam pictures are a bit pale and the maximum resolution is 1280x720 pixels. Dell equips the Latitude with a fingerprint scanner, which enables biometric access protection. A SmartCard reader is available as well, but you do not get TPM. Dell installs its own ControlVault technology instead, which offers the same functionality. We can find the usual accessories in the box: A quick-start poster and warranty information. You also get a recovery DVD for Windows 10 as well as a DVD with drivers. The Latitude has a docking port, so the port variety can be expanded with a corresponding docking station. Dell offers several solutions with prices between 100 and 300 Euros (~$111 and ~$333). Accessing the components requires the removal of the bottom panel. This is no problem and you just have to remove all the screws at the bottom of the base unit. There are additional plastic clips, but you do not need a sharp object, using your fingers will be sufficient. The Latitude is equipped with two memory slots, and one is still free. The M.2-SSD can be replaced by another model, and the fan can be cleaned to a limited extent. The battery can be replaced if necessary since it is only secured by a couple of screws. Dell ships the Latitude with a one-year warranty, but you can expand the service period. Dell offers numerous solutions; a three-year ProSupport, for example, is available for around 100 Euros (~$111). KeyboardThere are no differences between the review unit and its predecessor in terms of input device. Dell once again uses an illuminated chiclet keyboard with a numeric keypad. The illumination is controlled via function key and there are two illumination levels. The keys are slightly roughened and concave, have medium travel and they have a convenient pressure point. The same applies for the resistance of the keys. There is just minor bouncing during typing. All in all, Dell implements a convenient keyboard, which should also be sufficient for frequent writers. Touchpad & TrackPointThe touchpad of the Latitude supports multi-touch and has a surface area of around 10 x 5.4 cm, so there is sufficient space for gestures. They can be activated and deactivated individually in the settings of the pad. Most gestures are activated by default. The slightly roughened pad does not affect the gliding capabilities. Under the pad are two smooth mouse buttons with a short travel. Above the touchpad are three additional mouse buttons, which are primarily designed for the TrackPoint. The latter works well and allows precise cursor movements. Dell equips the Latitude with a matte 15.6-inch display and a native resolution of 1366x768 pixels. You can also get an optional Full HD screen. Our HD panel only manages low results for the luminance (235.7 cd/m²) and contrast (407:1). We expect more from a device in this price range, but there is at least no PWM flickering. 251 cd/m²226 cd/m²229 cd/m²243 cd/m²228 cd/m²235 cd/m²238 cd/m²229 cd/m²242 cd/m² Distribution of brightness LG Philips 156WHU X-Rite i1Pro 2 Maximum: 251 cd/m² (Nits) Average: 235.7 cd/m² Brightness Distribution: 90 % Center on Battery: 228 cd/m² Contrast: 407:1 (Black: 0.56 cd/m²) ΔE Color 10.02 | 0.5-29.43 Ø5.1 ΔE Greyscale 10.66 | 0.57-98 Ø5.3 61% sRGB (Argyll 1.6.3 3D) 39% AdobeRGB 1998 (Argyll 1.6.3 3D) 41.82% AdobeRGB 1998 (Argyll 2.2.0 3D) 60.9% sRGB (Argyll 2.2.0 3D) 40.48% Display P3 (Argyll 2.2.0 3D) Gamma: 2.48 Screen Flickering / PWM (Pulse-Width Modulation)ℹ 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: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18891 (minimum: 5 - maximum: 3846000) Hz was measured. We can measure DeltaE-2000 deviations of 10.02 for the colors ex-works, which is too high for a notebook in this price range. The target value would be smaller than 3 in general. We can also see a blue cast and the color spaces AdobeRGB and sRGB cannot be displayed. They are only covered by 39% (AdobeRGB) and 61% (sRGB), respectively. Display Response Timesℹ 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 White27 ms ... rise ↗ and fall ↘ combined↗ 10 ms rise ↘ 17 ms fallThe screen shows relatively slow response rates in our tests and may be too slow for gamers. In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 62 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (21.9 ms). ↔ Response Time 50% Grey to 80% Grey47 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise ↘ 25 ms fallThe screen shows slow response rates in our tests and will be unsatisfactory for gamers. In comparison, all tested devices range from 0.2 (minimum) to 636 (maximum) ms. » 78 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (34.5 ms). Dell only uses a TN panel with limited viewing angles for our review unit, so the display content is not visible from every position. Vertical shifts will quickly result in an inverted picture, but the situation is better for horizontal changes. Even multiple people can look at the display simultaneously. The Latitude can be used outdoors as long as it is not too bright. Otherwise, the low luminance and contrast will not be sufficient.

You get the usual features like a fingerprint scanner and docking port, while SmartCard reader and LTE modem are available as optional extras. The price of our test model is just under 1,000 Euros (~$1112). Other configurations are available and the least expensive model starts at 750 Euros (~$834). Strangely, it is also the model with the most powerful processor, the Intel Core i5-6440HQ quad-core. Note: The listed prices are without VAT. Intel's Core i5-6300U (Skylake) dual-core processor is a mainstream CPU and should provide sufficient performance for the majority of users. It is a frugal ULV model with a TDP of 15 Watts. The CPU runs with a nominal clock of 2.4 GHz, which can be raised to 2.9 (both cores) and 3 GHz (one core) via Turbo Boost, which is utilized on mains as well as battery power. We reviewed the predecessor of the Latitude 15 E5570 – the Latitude 15 E5550 – back in 2015. The latter was equipped with the Core i5-5300U processor. This is the Broadwell predecessor of the CPU in our test model, so this is a good chance to compare the two. The Skylake model manages about 15% better scores in our benchmarks, which is a result of the improved Skylake architecture as well as the slightly higher clocks. Users with very CPU-demanding applications might want more performance than the ULVs from Intel can offer. Dell therefore also offers configurations with the Core i5-6440HQ quad-core processor. This CPU has a big advantage in multi-core scenarios in particular. It is surprising that such a configuration is much cheaper than our test model. Our Polish colleagues already reviewed such a model. We listed the results in the comparison tables.

We did not encounter any problems. The PCMark scores are very good, but you can still improve the system performance by installing a second memory module. The activated dual-channel mode will increase the graphics performance. Users thinking about the quad-core configuration of the Latitude should consider that the stronger processor is hardly faster in practice. The CPU only has an advantage in applications that are optimized for multi-core processors. Drawbacks on the other hand are higher temperatures, increased power consumption and shorter battery runtimes.

It supports DirectX 12 and runs with a core clock of up to 950 MHz. The 3DMark scores are on the expected level for this GPU. It is possible to increase the graphics performance by installing a second memory module. The memory would then run in a dual-channel configuration, which will improve the GPU performance. If you want an even faster GPU, you will have to get a Latitude model with a dedicated Radeon R7 M370 graphics core. Such a model was tested by our Polish colleagues. 3DMark 11 Performance 1438 points3DMark Ice Storm Standard Score 51106 points3DMark Cloud Gate Standard Score 5456 points3DMark Fire Strike Score 720 points Help 3DMark 11 - 1280x720 PerformanceDell Latitude E5570 N026LE557015EMEA Radeon R7 M370, 6440HQ, Samsung SSD 850 EVO 250GB 3027 Points +111% HP EliteBook 850 G3 HD Graphics 520, 6500U, Sandisk X300 SD7SN6S-256G-1006 1461 Points +2% Dell Latitude 15 E5570 HD Graphics 520, 6300U, Samsung SSD PM871 MZ7LN128HCHP 1438 Points Lenovo ThinkPad L560-20F10026GE HD Graphics 520, 6200U, WDC Slim WD10SPCX-21KHST0 1339 Points -7% Toshiba Tecra A50-C-1G0 HD Graphics 520, 5200U, Toshiba HG6 THNSNJ256GVNU 1232 Points -14% Dell Latitude E5550 Broadwell HD Graphics 5500, 5300U, Samsung SSD PM851 128 GB MZ7TE128HMGR 1028 Points -29% The Latitude can also be used for some gaming. Its hardware is powerful enough for many games in low resolutions and with low/medium details. However, this is only the case for simpler titles with low hardware requirements. More demanding titles like Hitman are not playable. You can increase the frame rates with a second memory module (dual-channel mode), which will result in 10 up to 30% more frames. The fan is often deactivated while idling. The system will be silent in these scenarios. You can notice the fan under load and we can measure up to 34.7 dB(A) during the stress test. Here we can notice that the CPU does not utilize its full potential. There are unfortunately some annoying noises, because we can hear occasional coil whining.

Value 1: Pink Noise 100% vol.; value 2: audio off We can measure a maximum idle consumption of 8.7 Watts, which is on the expected level. The consumption will rise to 40 Watts for a short period at the start of the stress test before the CPU clock is reduced. The CPU clock fluctuates during the stress test, so the power consumption will fluctuate as well. The maximum consumption in this scenario is 29.2 Watts. The power adapter has a rated output of 65 Watts. The Latitude manages a runtime of 10:32 hours in our practical WLAN test, which simulates web browsing via script. The power plan "Balanced" is active, the energy-saving features are turned off and the display brightness is adjusted to around 150 cd/m². If you use the Latitude to watch videos, it does not last quite as long, but the runtime of 9:31 hours is still great. We determined this value with a loop of the short movie Big Buck Bunny (H.264, 1920x1080 pixels). The energy-saving features are turned off, and the display brightness is reduced to 150 cd/m². All in all, the Latitude manages much longer battery runtimes compared to its Broadwell predecessor. This is also a result of the increased battery capacity (62 Wh vs. 51 Wh). Attention: You should have a look at the battery capacity when you buy the Latitude, because Dell also offers Latitude models with a battery capacity of 47 Wh. These models do not last as long as our test model. Dell also lists an optional 84 Wh battery on its website.

Cons- dark, low-contrast display - only one year warranty Dell's Latitude 15 E5570 is a pure business notebook with a 15.6-inch screen. The design does not really differ from the predecessor, but the changes are bigger inside the device. The ULV processor from the Skylake generation offers plenty of performance for all common tasks. If you need more CPU performance, you should get a configuration with a Core i5 quad-core processor. The device is usually quiet and does not get really warm. An SSD ensures a responsive system and you can also replace the drive. This requires the removal of the bottom panel, which is no problem. Similar to the predecessor, the keyboard can once again convince, and you also get great battery runtimes. The Latitude from Dell is a convenient notebook in many respects, but there are some drawbacks. The device offers the usual business features like a fingerprint scanner, docking port, SmartCard reader (optional), but Dell waives TPM and implements its own technology called ControlVault instead. The display will not impress anyone. Dell uses a dark and low-contrast panel with limited viewing angles. We expect more from a device priced at 1,000 Euros (~$1112). A device like the Latitude should also be equipped with a USB Type-C port.
