Many users consider the Dell Inspiron 15 3520 as the smoothest national office laptop in the price range of 15-16 million VND. Equipped with the 12th generation Intel Core i5-1235U processor released at the end of 2021, it boasts numerous improvements in aspects such as performance and speed. If you haven't found a suitable office laptop yet, feel free to check out the Dell Inspiron 15 3520 review below.
Design Identical to Its Predecessor
If you're excited about the design of the Dell Inspiron 15 3520, you'll be disappointed as this laptop doesn't offer many differences from its predecessors. The machine's body is crafted entirely from 100% plastic, providing a sensation that is not particularly premium or robust. The black-toned casing tends to cater more towards male users.
The hinge mechanism has received quite a bit of mixed feedback. Although it enhances typing comfort, it also has to withstand considerable force from the machine's body and the user's typing force.

Stable Configuration for Office Work
In terms of technical specifications, the Dell Inspiron 15 3520 is equipped with the following configuration:
- CPU: Intel Core i5-1235U
- RAM: 8GB DDR4 2666MHz
- SSD: 256GB NVMe
- GPU: Intel Iris Xe/Intel UHD Graphics
The chip in the Inspiron 15 3520 boasts up to 10 cores, 12 threads, and 2 P-Cores. Given the current price range of 15-16 million VND, users can mostly find machines equipped with 6-core, 12-thread processors. Moreover, the number of cores, threads, and clock speed of the chip are all higher than last year's i5 generation. According to the Cinebench R23 score, the single-core and multi-core scores of the Core i5-1235U are even comparable to the i7-1165G7 chip.
During real-world usage, Dell Inspiron 15 3520 delivers a smooth experience for office work, reading news, and web browsing. Despite having only 8GB of RAM and a 256GB SSD, there's no need to worry as both are upgradeable.
Especially, the chip also features a seamless integration of P-Cores and E-Cores with Intel 7 process technology. This ensures the machine operates smoothly while being power-efficient.

High Refresh Rate 15.6-inch Display up to 120Hz
The screen specifications of the Dell Inspiron 15 3520 laptop are as follows:
- Size: 15.6 inches
- Color Coverage: 63% sRGB
- Panel Type: WVA
- Brightness: 250nit
- Refresh Rate: 120Hz
Inspiron 15 3520 impresses with its high refresh rate display, reaching up to 120Hz. This feature is usually found only in gaming laptops priced below 20 million VND. Compared to the 60Hz refresh rate, the 120Hz display provides a smoother image experience, significantly reducing eye strain. Additionally, being equipped with a WVA panel also significantly widens the viewing angles.
Reviewing other features of the Dell Inspiron 15 3520 laptop
The machine uses a full-size chiclet keyboard with a fairly shallow key travel and no LED backlighting. The laptop is also not equipped with a fingerprint sensor, lacks Thunderbolt and USB Type-C charging ports...
Overall, the equipment of the Inspiron 15 3520 is quite basic and somewhat inferior compared to other laptops in the 15-16 million VND price range. However, each detail is meticulously invested in to provide the best user experience. For example, the computer speakers are of extremely good quality, producing loud and clear sound rather than just being there for show like some other laptop models.

The Dell Inspiron 15 3520 laptop can be considered an extremely optimized choice for light tasks. Whether it's office work, online studying, running ads... the laptop still handles tasks very smoothly and quickly. Although the color coverage of the screen is not good enough for graphic design or color grading, the 120Hz screen also meets entertainment, gaming, and work needs very well.
