Business laptops are usually not the type of laptop with an appearance that makes others admire, but the Dell Latitude 7455 leaves a strong impression at first sight. This mobile laptop is equipped with a Qualcomm chip, has a sharp 14-inch screen in a compact and elegant appearance, along with many reasonable configuration options and is perfect for basic needs. If it weren’t for its price, it would actually be the top choice for countless people.
What is worth mentioning is that it is not the powerful configuration that creates the highlight, but Dell’s simple yet very practical design elements that are the main factors that make this laptop stand out. 14-inch screen with reasonable 16:10 ratio, high clarity and bright, accurate colors, providing an excellent viewing experience. The keyboard is good, the touchpad is spacious. It even has a USB-A port and a 3.5mm headphone jack. What more could you expect from a compact business laptop?

1. Dell Latitude 7455 laptop design review
The design of the Dell 7455 is very sophisticated. It has no color options other than dark gray. The entire body of the device is made of metal, every corner is gently rounded, and the sparkling metal adds elegance. Dell’s finishing quality is beyond question, the ruggedness of the Latitude line has been clearly demonstrated over countless years. However, its back has a bit of flexibility – not much, but still there. This is a necessary factor to better protect the screen.
Overall, the Dell 7455’s design is a bit too ‘safe’, but this is a beautiful and powerful laptop that straddles the line between ‘attractive’ and ‘modest’.

The 124-inch screen makes the overall size of the Dell Latitude 7455 a bit larger than models like the XPS 13, but it doesn’t feel large or heavy at all. The maximum thickness of the device is only 16.9mm at the hinge and gradually shrinks to the front edge. Weighing only 1.45kg, it is extremely light to carry for daily use.
The hinge design of the Dell Latitude laptop line has so far scored points for its sturdiness, but on the Dell 7455, it also has more intelligence with a raised hinge that resembles the standard of modern Ultrabooks. The lift distance is not high, but enough to provide more airflow for the bottom heat vent, and also helps tilt the keyboard forward a bit to create a more comfortable typing feeling. This is a truly worthwhile upgrade.
Some users looking at the design of this Dell laptop may want it to be a bit thinner, but it’s really not necessary because Dell has made reasonable use of the extra space. Two USB 4 Type-C ports are located in the left corner, both supporting Power Delivery and DisplayPort 2.1, accompanied by a microSD card slot. Looking to the right, there is a USB-A 3.2 Gen1 port and a 3.5mm headphone jack. Above the screen, we have a 1080p webcam that supports Windows Hello with a privacy shutter. Too complete for office work needs.

The device’s wireless connection is also guaranteed with the Qualcomm FastConnect 7800 chip, supporting up to Wi-Fi 7 and Bluetooth 5.4. On the other hand, if needed, you can also choose to integrate 5G bandwidth, but this option will be much more expensive and you will need to book it separately with Dell. The only limitation of this 14-inch laptop is probably its limited upgradeability, its RAM is soldered to the mainboard, only the SSD can be replaced.
2. Dell Latitude 7455 keyboard and touchpad
The keyboard of the Dell Latitude 7455 is very basic. Backlit keyboard with easy-to-use chiclet design. The Shift, Tab and Ctrl keys are reasonably sized, and the Enter key is both wide and high, very comfortable. Furthermore, the keys have a light but firm response, providing an excellent feel. Another commendable point is that the row of function keys is very complete, and it is a hard key, not an unintuitive touch row.

However, there is also a small complaint about the two up and down arrow keys being only half the height of the other keys, and the power button and fingerprint reader are located too close to the Delete and Backspace keys. In general, with this key layout, users will need some time to get used to it to avoid pressing the wrong button.
In contrast to the keyboard, the touchpad of the Dell 7455 may not be as interesting, but it is not strange, because its task is only to move anyway, even for those who are used to using external mice, the touchpad It’s almost a ‘never touch’ zone. However, no matter what you say, Dell also designed the touchpad for the Latitude 7455 very well, from simple touches to multi-finger gestures all work smoothly. If there is anything to complain about, it’s just that this type of mechanical touchpad is ‘less luxurious’ than the haptic touchpad that is becoming a trend today.
3. Screen of Dell Latitude 7455
If you have to look at a screen all day long, you’ll probably be satisfied with the Latitude 7455’s 2560 x 1600 pixel IPS display. The 216ppi pixel density produces sharp text, and the combination of a matte anti-glare layer (dim) and 421 nits brightness will help you work effectively even in unfavorable lighting conditions, such as in a bright office or outdoor cafe.
It must be said that the image quality on this screen is truly outstanding. The 1829:1 contrast is very commendable for an IPS panel, and color reproduction is very good. This monitor covers 99.9% of the sRGB color gamut, perfect for most work purposes, and its average Delta E is only 1.31, showing very realistic and accurate colors, with only one Slight saturation in red.

If there is one point to criticize, it is that the screen specifications seem a bit modest compared to competitors like the Microsoft Surface Laptop 7. The Surface Laptop 7’s screen is a bit brighter, the refresh frequency is also high (120Hz), color accuracy is also high and can be used on both sRGB and DCI-P3 color spaces. In contrast, the Dell 7455’s 60Hz screen only covers 80.3% DCI-P3 and 75.9% AdobeRGB, these two parameters are not enough to make the Dell 7455 suitable for work related to color editing and design.
Additionally, the Dell 7455’s 1080p webcam is good enough for its intended uses. As for Windows Hello, it’s a good alternative to a fingerprint reader, and overall image quality is acceptable. Although upon closer inspection, the small details are still not very smooth, and the color balance is slightly inclined towards warm, but the overall image is quite pleasant and natural. The privacy shutter is also a plus.
Finally, I must also praise the speakers of this Dell laptop, it is quite impressive for a business laptop. Qualcomm Aqstic Speaker Max technology may sound like marketing, but the results are remarkable. A pair of 2W tweeters and two 2W woofers combine to produce full and clear sound, making music sound quite good. Although it doesn’t reach the pinnacle of good-sounding laptops like Apple’s Macbook, it’s still pretty good overall.
4. Dell Latitude 7455 performance
Dell offers two Qualcomm processor options, the Snapdragon X Plus X1p-64-100 with 10 cores or the Snapdragon X Elite X1E-80-100 with 12 cores. And the model evaluated in this article is the 12-core version, its price is about 3 million VND higher than the 10-core version.
The basic RAM capacity of the Dell 7455 is 16GB LPDDR5X, and it is tightly soldered to the motherboard. If you want to reserve for the future or want to have more temporary memory capacity to use, you can also upgrade to 32GB. Internal storage, on the other hand, is much more comfortable, with flexible options from 256GB to 1TB, which you can change anytime you want.
As expected, the Snapdragon X Elite X1E-80-100 delivers very respectable performance in everything not related to the GPU. Geekbench scores show that the Latitude 7455 achieved a single-core score of 2,723 and a multi-core score of 14,282. This is a very impressive theoretical score when placed next to competitors using Intel, AMD and Apple M-series chips.
Although not strong in graphics, the raw performance of the Snapdragon X Elite CPU helps the Dell 7455 complete all office tasks with the utmost ease (Photo: Joseph Maldonado).
In fact, this score is on par with Intel’s latest generation Lunar Lake processors. Compared to the Intel Core Ultra 9 288V equipped in the Asus Zenbook S14 laptop, the Qualcomm chip on the Dell 7455 is only 3% slower in the single-core test, but is 38% ahead in the multi-core test in Geekbench.
A similar situation also occurred in the Cinebench 2024 scoring software, the Qualcomm chip was only 3% behind in the single-core test, but surpassed 82% in the multi-core test.
Although we know that these results are only good in theory, they also prove that the Dell Latitude 7455 is fast enough for most everyday applications. More specifically, its heat efficiency is very low, even when the machine is set to High Performance mode, the fan sound is very quiet, we only hear the wind when the CPU and GPU start to ‘work hard’. but the fan sound is not enough to cause trouble for people sitting next to it.
If we say what is the biggest weakness of this chip, it is graphics performance. In the 3DMark Time Spy test, the Latitude 7455 scored an overall score of 1925. This score is 41% lower than the Intel Meteor Lake generation GPU in the Dell XPS 13 9340. Compared to the newer generation Lunar Lake, For example, Asus Zenbook S14, this gap even widens to 56%. Simply put, the Snapdragon X Elite is still far behind in terms of GPU performance.
In return, battery life is a typical highlight for Snapdragon devices, and the Dell 7455 is no exception. In the test of playing HD video from full battery to empty, the device lasted about 16 hours and 38 minutes. Although it did not reach the 20-hour mark like some other models, it was not bad at all.
On the other hand, when the battery is depleted, Dell also claims that the Latitude 7455’s ExpressCharge Boost feature can quickly charge the battery to 35% in just 15 minutes, and although the test results are not close to the same, they are still quite good. Good. With the included 65W USB-C adapter, this laptop can charge the battery from a depleted state from 0% to 25% in 15 minutes, to 50% in 29 minutes and to 100% full in over an hour. However, users should note that this fast charging will reduce the life of the laptop battery faster than standard charging. Therefore, never let your laptop fall into a state of power failure.
5. Should I buy a Dell Latitude 7455 laptop or not?
This was the beginning of the Windows-on-Arm laptop era, but laptops like the Dell Latitude 7455 have proven to be a very competitive choice when compared to any laptop from Intel, AMD or Intel. Apple. If you only use this laptop for work, and don’t care about graphics performance or software compatibility, then it will definitely be the best tool for you to get your work done.
The biggest problem with the Latitude 7455 currently is the price. With a price of about 34 million VND, this is not a budget-friendly laptop for office workers. And if users are also economical enough, in this price range there are also many high-end options with better graphics performance.
Anyway, the Dell Latitude 7455 is also an option, and if you have plenty of money and a tendency to look forward to the future, this will be one of the attractive shopping suggestions at the end of 2024 and early 2025. .
