Dell Latitude 3400 Laptop Review: An affordable business laptop with long battery life
The Latitude 3400 is one of Dell's entry-level 14-inch business laptops and succeeds the Latitude 3490 despite its name. Our review unit currently retails for between €550 (~$601) and €600 (~$656), making it the cheapest device in the series that Dell currently offers. We shall compare the Latitude 3400 against the HP ProBook 445 G6 and 440 G6, along with the Lenovo ThinkPad E490 and E495.

Case & Connectivity - Dell includes plenty of ports
The Latitude 3400 has a black plastic chassis, which for the most part has a matte and roughened finish. The sides are plastic too, but Dell has opted for a glossy and smooth finish instead. Our review unit is well-made overall and does not have any serious stability or build issues. Dell installs the battery beneath the bottom plate as is the case with most modern laptops, so you must disassemble the laptop to access it.
Dell equips the device with three USB Type-A ports, specifically two USB 3.2 Gen1 and one USB 2.0, along with one USB 3.2 Gen1 Type-C port. The latter supports DisplayPort too, but you must use a separate adapter to utilise this functionality. The Latitude 3400 has three video outputs if one includes DP over Type-C, as Dell has included HDMI and VGA ports too. The Type-C port also supports USB Power Delivery (PD) for charging the Latitude, while there is Gigabit Ethernet onboard if you need a wired internet connection.
There is also an SD card reader, but it is one of the slowest of its kind. The one in our review unit averaged 32.3 MB/s when copying large blocks of data, which dropped to 23 MB/s when transferring 250 5 MB JPG files. We tested the card reader using our Toshiba Exceria Pro SDXC 64 GB UHS-II reference card, which is capable of much higher transfer speeds than the Latitude can manage.
Finally, Dell has integrated an Intel Wireless AC 9560, which supports up to IEEE 802.11 ac Wi-Fi as its name suggests. Our review unit achieved good transfer speeds during our iperf3 Client Wi-Fi tests, although please keep in mind that we conducted these tests with the Latitude next to our reference router and removed all other Wi-Fi connected devices from the immediate vicinity too.

Input Devices - A backlit Latitude
Dell equips the Latitude 3400 with a backlit chiclet keyboard, which consists of flat keys that have a slightly roughened texture. The keys in our review unit have short strokes and clear pressure points, of which we are fans. The keyboard deck gives way a bit while typing, but not disturbingly so during our tests. The backlighting has two levels that can be cycled with a function key, which is handy. Overall, Dell has equipped the Latitude 3400 with a decent keyboard that delivers in all areas.
There is also a multi-touch trackpad that measures around 10.5 x 6.5 cm (~4.1 x 2.6 in), which is large enough to perform multi-finger gestures on in our opinion. The trackpad has a smooth texture to it that we found easy to move our fingers across and perform swiping gestures. The one in our review unit remains accurate into its corners too, and integrates two mouse buttons, which have short strokes and clear pressure points.
Display - IPS and matte, but dim and washed out
As we mentioned earlier, Dell equips the Latitude 3400 with a 14-inch 1080p panel that it has given a matte finish. The IPS panel achieved an average maximum brightness of 226.9 cd/m² according to X-Rite i1Pro 2 and a contrast ratio of 500:1, which are both too low for our liking. We expect modern laptops to reach at least 300 cd/m² and 1,000:1, so the Latitude 3400 falls well short in both regards. However, none of our comparison devices meet these thresholds, so the Latitude 3400 is in good company in that regard. Our comparison devices all have more contrast-rich displays than the Latitude 3400 does, though.
Unfortunately, the Latitude 3400 also uses the eyestrain and headache-inducing pulse-width modulation (PWM) to regulate luminosity at 90% brightness and below. The panel in our review unit flickers at 1,000 Hz, which may be high enough to avoid causing issues for most people. We would still recommend trying out the Latitude 3400 before you buy it if you are PWM sensitive, as the PWM frequency may be low enough to cause you the issues that we described.

The display backlight flickers at 1000 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 90 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 1000 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8492 (minimum: 5 - maximum: 343500) Hz was measured. | |||
Dell has done a good job of factory calibrating the display, with our review unit only just missing our ideal value of 3 for DeltaE 2000 colour deviations. The display only covers 59% of the sRGB colour space and 38% of AdobeRGB though, making it colour accurate enough for only hobbyist photo and video editing.
The IPS panel also has stable viewing angles, so you should have no issues with reading the display from acute angles. However, while the matte finish diffuses reflections, the Latitude 3400 cannot get bright enough to overcome bright sunshine. Its meagre contrast ratio makes our review unit look washed out in bright sunshine too, as the photos below demonstrate. Hence, the Latitude 3400 is best suited as an indoor-only laptop.
Performance - An entry-level office laptop
In short, the Latitude 3400 is powerful enough for all general Office and Internet-based applications. Dell currently sells our review unit for between €550 (~$601) and €600 (~$656), but it also offers other configurations should you need more powerful hardware.
Processor
At the heart of our review unit is an Intel Core i3-8145U, a dual-core processor based on the company's Whiskey Lake architecture. The CPU has a 2.1 GHz base clock and can use Intel Turbo Boost to increase its clock speed up to 3.7 GHz on two cores or 3.9 GHz on one core. The Core i3-8145U supports Intel Hyper-Threading too, allowing it to execute up to two threads per core simultaneously.
The Core i3-8145U temporarily maintains 3.7 GHz during multi-threaded benchmarks such as Cinebench R15 Multi 64Bit, but clock speeds quickly drop to between 3.1 and 3.2 GHz. However, the device can maintain between 3.7 and 3.9 GHz in the corresponding single-threaded benchmark. The Latitude 3400 does not throttle CPU performance on battery either, so these scores represent what the device should achieve regardless of whether it is connected to the mains.
We also checked how well the CPU performs under sustained load by running CB R15 Multi 64Bit on a loop for at least 30 minutes. Our review unit throttles slightly after the first benchmark run-through, but it then stabilises at around 310 points for the remainder of the loop save for one aberration.
We expected more from the Core i3-8145U here, though. A device the size of the Latitude 3400 should have no issues with cooling a dual-core ultra-low-voltage (ULV) CPU, but our review unit cannot keep it at peak clock speeds, which is rather underwhelming.

System Performance
Our review unit performed well in daily use, which PCMark reinforces. We did not encounter any performance issues in daily use, but the Latitude 3400 would benefit from dual-channel mode, with our review unit running in single-channel mode. Switching to the former would require adding a second, and identical, SODIMM module.

Graphics Card
Dell has not equipped the Latitude 3400 with a dedicated GPU, so our review unit must rely on the UHD Graphics 620 that Intel integrates within the Core i3-8145U instead. The GPU supports DirectX 12, can clock up to 1,000 MHz and has a hardware video decoder that can handle tasks such as streaming from Netflix with ease. Our review unit performed just as expected in 3DMark, but it could achieve better scores if it were running in dual-channel mode.

Gaming Performance
The UHD Graphics 620 is not powerful enough to play modern triple-A games, but you should have no issues with older titles such as "BioShock Infinite" or "League of Legends". However, our review unit can only render the former at playable framerates in 720p and on the lowest graphics preset, so the game will not be that pleasing on the eye. Again, dual-channel would improve framerates, but not massively so.

Emissions - Acceptable fan noise and surface temperatures
Fan Noise
Our review unit often runs silently when idling, but its single fan occasionally reaches 32.8 dB(A) even during menial tasks. The fan peaked at 38.1 dB(A) during our stress tests too, but this does not sound overly noisy to our ears.

Temperature
We subjected our review unit to a combined FurMark and Prime95 stress test, which we left running for at least an hour to see how it fared under extreme load conditions. The Latitude 3400 performed just as well on battery as it did on mains power, during which its CPU initial operated at between 3.4 and 3.7 GHz. However, it plummeted to 1.2 GHz after a few moments, a level that it maintained for the remainder of the test. By contrast, the GPU always remained at around 900 to 950 MHz, but that is probably because the components share their thermal design power (TDP). In practical terms, this means that the CPU and GPU are unable to operate at peak clock speeds simultaneously. You should not experience this degree of throttling, even when gaming though, as our stress test pushes devices to their limits.
Most of the Latitude 3400 remained cool to the touch even during our stress test, with the palm rest never exceeding 27 °C (~81 °F). Only one area reaches 40 °C (~104 °F), so the device should never feel too hot to hold even if you are pushing it to its limits. Expectedly, the Latitude 3400 runs more coolly when idling.
(±) The maximum temperature on the upper side is 40.8 °C / 105 F, compared to the average of 34.3 °C / 94 F, ranging from 21.2 to 62.5 °C for the class Office.
(+) The bottom heats up to a maximum of 39.8 °C / 104 F, compared to the average of 36.8 °C / 98 F
(+) In idle usage, the average temperature for the upper side is 26.8 °C / 80 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 26.7 °C / 80.1 F and are therefore cool to the touch.
(±) The average temperature of the palmrest area of similar devices was 27.6 °C / 81.7 F (+0.9 °C / 1.6 F).
Speakers
Dell equips the Latitude 3400 with stereo speakers that it has placed facing downwards at the front of the device. The ones in our review unit output audio that sounds rather thin and tinny with a complete lack of bass. They are also overly quiet, so we would recommend using external audio equipment like headphones or speakers where possible.

Power Management - Acceptable power consumption and great battery life
Power Consumption
The Latitude 3400 consumed between 2.4 W and 47 W when switched on during our tests, which is reasonable for a dual-core business laptop. However, it can only maintain the latter wattage for a few seconds and averages 31 W under sustained load. Dell includes a 65-W charger in the box, so the Latitude 3400 should always keep charging even if it is being pushed to its limits.

Battery Life
The Latitude 3400 has a 56 Wh battery, which lasted for an impressive 9:44 hours in our practical Wi-Fi battery life test. We conduct this test by running a script that simulates the load required to render websites. We also set devices to the Balanced Windows 10 power profile, disable all power-saving features and set the display to approximately 150 cd/m². Only the Latitude 3490 lasted longer than the Latitude 3400 of our comparison devices, for reference.
Pros
Cons
Verdict
The Dell Latitude 3400 is a mundane business laptop, especially when configured with an Intel Core i3-8145U processor. However, it is powerful enough for all general office and internet-based tasks. It also never gets too hot or noisy.
The inclusion of a fast NVMe SSD ensures that the system runs smoothly too, although you could swap this for a larger capacity drive should you need to do so. You would need to disassemble the device to do this.
The Dell Latitude 3400 is a solid and affordable 14-inch business laptop that should not let you down while at work.
We are fans of the keyboard and trackpad too, as we are with the battery life. Likewise, the Latitude 3400 has a good selection of ports, including USB Type-C that supports DisplayPort and USB PD. However, its dim and low-contrast display disappointed us, while the slow card reader and 12-month standard warranty are a shame too. Overall, the Dell Latitude 3400 is a decent office laptop that will appeal to those who are on a limited budget.
