Dell Inspiron 16 Plus 7640 is equipped with a powerful Intel Core Ultra processor, a beautiful 16-inch 2.5K resolution screen, and a neat, elegant design, promising to meet the needs of office work, study and entertainment of users.
1. Dell Inspiron 16 Plus 7640: Design and appearance!
This 16-inch Dell laptop has an elegant and professional design, suitable for the office environment. The edges and corners are gently rounded, creating a soft feel when holding. The hinge is firmly designed, allowing for easy opening with just one hand. The bottom of the laptop is equipped with rubber feet, which help lift the device up a bit for better heat dissipation. The heat vents are arranged reasonably on the bottom and sides, ensuring good air circulation.
Dell Inspiron 16 Plus 7640 is made entirely from high-quality aluminum alloy, providing a luxurious and durable feel. The entire body of the device is covered with Ice Blue matte paint – a delicate combination of light blue and silver. This matte paint layer not only creates a delicate beauty but also effectively prevents fingerprints, helping the laptop always maintain a clean appearance.

The familiar Dell logo is placed in the center of the top of the screen, creating a simple highlight but with high recognition value. The overall design of the Inspiron 16 Plus 7640 has a business laptop style – simple, elegant and professional.
With a 16-inch screen size, the Dell Inspiron 16 Plus 7640 has overall measurements of 356.8 x 250.6 x 16.7mm. This is quite a compact size for a large-screen laptop, showing Dell’s efforts in optimizing the design.
The weight of the device is 1.9kg, relatively light compared to its size. Users can easily carry the Inspiron 16 Plus 7640 on the go without feeling too heavy. However, compared to 13 or 14 inch Ultrabook models, the device is still significantly heavier.
2. Dell Inspiron 16 Plus 7640: Screen!
During actual use, the Dell Inspiron 16 Plus 7640 screen provides very good display quality. 2.5K resolution on 16 inch size provides high pixel density, helping images and text appear sharp. In addition, it also has another Full HD screen option for those with less display needs.

According to the manufacturer, this screen has 100% sRGB color coverage, wide viewing angle, 120Hz refresh rate and 300 nits brightness. Using the Spyder X screen color calibration tool, the color coverage measurement results of the Dell Inspiron 16 Plus 7640 are obtained as follows:
sRGB: 99.6%
Adobe RGB: 69.9%
DCI-P3: 75.1%
Based on this result, it can be seen that the sRGB color coverage is also quite close to the number given by the manufacturer, the difference is not significant. Although the two color parameters Adobe RGB and DCI-P3 are not really impressive, the nature of this laptop is aimed at office users, not professional graphics people, so it is not a big problem.
Besides, there is also a small plus point, which is that the actual screen brightness measured is 325 nits, 25 nits more than the parameter Dell claims. Although the difference is only very small, the more it is, the more beneficial it is for users.
Regarding color accuracy, the average Delta E value of the screen is 1.27, the highest is 2.25. With an average Delta E value of less than 2, the Dell Inspiron 16 Plus 7640’s screen provides very good color accuracy. Most users will not be able to tell the difference between the displayed color and the standard color.
3. Dell Inspiron 16 Plus 7640: Keyboard and TouchPad!
The keyboard of the Dell Inspiron 16 Plus 7640 has a spacious design, making good use of the space of the 16-inch body. However, it’s worth noting that Dell has not integrated a numeric keypad, a feature commonly found on large-screen business laptops.
The keyboard is also Ice Blue, in tune with the overall color tone of the laptop. The keys are designed in a chiclet style, with a reasonable distance between the keys, helping to minimize typing errors. The typing experience on the Dell Inspiron 16 Plus 7640 is quite comfortable. The key travel is not too long, but still ensures good feedback. The bounce of the keys is also moderate, neither too hard nor too soft, helping users type without tiring their hands.

The keyboard backlight can be adjusted for brightness, helping to work in low light conditions while still seeing the keys clearly.
The TouchPad of the Dell Inspiron 16 Plus 7640 is large in size and responds well to multi-point movements. The surface of the TouchPad is smooth, helping fingers slide smoothly across the surface without causing the feeling of pulling on the brush. Operations such as scrolling, zooming or rotating images are all performed easily.
However, on the Dell Inspiron 16 Plus 2024 version, there is an improvement: the company has removed the fingerprint scanner and does not have Windows Hello, to log into the system we are required to enter a password. This is quite annoying.
4. Dell Inspiron 16 Plus 7640: Connection port!
Dell Inspiron 16 Plus 7640 is equipped with up to 7 connection ports, meeting the needs of daily use as well as professional work. Starting from the left edge, we have the charging port, HDMI 1.4 port, USB-A 3.2 Gen1 port and Thunderbolt 4.0 port (supports DisplayPort and Power Delivery charging). On the left side, we have another USB-A 3.2 Gen1 port, 3.5mm audio jack and SD card slot.

This number of ports can be said to be sufficient for office users in daily work. And there is one point that you need to note, that on the Inspiron 16 Plus 7640, the discrete and integrated GPU versions will have slight differences in port quality, specifically the version with a separate card has a microSD port instead of SD, and the HDMI is the better 2.1 standard.
5. Dell Inspiron 16 Plus 7640: Battery and Charger!
Dell Inspiron 16 Plus 7640 uses a 6-cell battery and comes with a 90W AC charger. According to the manufacturer, this battery can be used continuously for 16 hours, and the recharging speed is also very fast, from 0- 80% is only about 60 minutes.
Actual usage shows that, although it does not reach the same number, the machine still gives very good working time. In Energy Saving mode and screen brightness reduced to 46% (150 nits), it reached 13 hours and 12 minutes, enough for almost all day use, assuming we used the device in balanced mode, With higher brightness, it can also fully meet a working day without needing to be charged midway.
6. Dell Inspiron 16 Plus 7640: Hardware and performance!
Following market trends, Dell has also upgraded its Inspiron line with Intel Core Ultra chipsets. The model used for evaluation in this article uses Core Ultra 7 155H with 16 cores and 22 processing threads, maximum clock speed of 4.8 GHz. In the Cinebench R23 test, it achieved 1,779 single-core points, 16,396 multi-core points, very fast and smooth office task performance.

The Intel Arc integrated graphics card also gave quite good benchmark results, 3DMark Time Spy reaching 3,471 points. Graphics performance is generally adequate for common needs, can play some light games and work with 2D graphics.
Additionally, it also comes with 32GB Dual-Channel LPDDR5x RAM. The read speed of RAM is 71,852 MB/s, the write speed is 73,112 MB/s and the copy speed is 80,332 MB/s, while the latency speed is 157.6ms.
The device’s internal memory has a capacity of 1TB, M.2 PCIe 4.0 SSD type. Its sequential read speed is 6,157.01 MB/s, sequential write speed is 4,787.99 MB/s, random 4K read speed is 88.99 MB/s, and random 4K write speed is 263 ,11MB/s. High.
Let’s talk more about heat dissipation performance. Because the power consumption of the Intel Arc GPU is not high, it does not need too much space for heat dissipation, inside the body there is only a single fan and dual heat pipes. After 5 minutes of testing with AIDA64, at 55W CPU power consumption, the machine temperature was only 68 degrees, completely cool.
7. Conclusion
From the reviews above, it can be objectively commented that the Dell Inspiron 16 Plus 7640 is a powerful laptop, meeting the needs of office users and basic content creation. With a luxurious design, large high-resolution screen, stable performance and effective cooling system, the device promises to bring a good working and entertainment experience to users.
However, with some weaknesses such as low Adobe RGB and DCI-P3 color coverage, the integrated GPU is only enough for 2D graphics tasks, users need to consider carefully before deciding to buy. Reference price of Dell Inspiron 16 Plus 7640 is as follows:
