MagyarDell Latitude 15 E5570 Notebook Review
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.
Case
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.
Connectivity
The port equipment did not really change between the E5550 and E5570. 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.
SD-Card Reader
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).

Communication
The WLAN module is provided by Intel and the chip has the designation Wireless-AC 8260. 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.
Webcam
The webcam pictures are a bit pale and the maximum resolution is 1280x720 pixels.
Security
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.
Accessories
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).
Maintenance
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.
Warranty
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).
Input Devices
Keyboard
There 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 & TrackPoint
The 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.
Display
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.

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.

Performance
Dell's Latitude 15 E5570 is a 15.6-inch business notebook with sufficient performance for all common scenarios. 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.
Processor
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.

System Performance
A fast Solid State Drive and a powerful processor ensure a smooth and responsive system. 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.

GPU Performance
Graphics of our review unit are handled by Intel's HD Graphics 520 GPU. 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.

Gaming Performance
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.

Emissions
System Noise
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.

Temperature
The Latitude executes our stress test (Prime95 and FurMark) similarly on mains as well as battery power. The processor can maintain 2.8 GHz for about a minute, before the clock will drop to 1.5-2.2 GHz for the rest of the test. The GPU can maintain 950 MHz. The device does not really get warm; only one spot surpassed 40 °C during the stress test.
(+) The maximum temperature on the upper side is 37.3 °C / 99 F, compared to the average of 34.2 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(±) The bottom heats up to a maximum of 41.5 °C / 107 F, compared to the average of 36.7 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 29.3 °C / 85 F, compared to the device average of 29.5 °C / 85 F.
(+) The palmrests and touchpad are cooler than skin temperature with a maximum of 27.5 °C / 81.5 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.8 °C / 82 F (+0.3 °C / 0.5 F).

Speakers
The stereo speakers are located at the front edge of the bottom panel. They create a decent sound you can also listen to for quite a while. The speakers manage a high maximum volume. You can also adjust the sound to your own preferences via preloaded Dell Audio software.

Energy Management
Power Consumption
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.

Battery Runtime
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.

Verdict
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.
