87.2% Dell Latitude 7400 Laptop Review: Even the high end is not free from weaknesses | Notebookcheck
Dell's 14-inch business laptop boasts a long battery life, an excellent keyboard and a fast NVMe SSD. The matte IPS display, however, could have a greater maximum brightness. In addition, the fan emits a high-pitched whistling noise.

70% Dell Latitude 7400 laptop review: A step in the right direction
Source: Gadgets Now English
Dell’s Latitude range of laptops has always been unique in its own ways. While the design is sturdy and looks elegant for the most part, the features inside add to the overall package without much corner cutting. With this, Dell seems to have successfully managed to club design with mobility and the required power so it can be used literally anywhere with ease. However, if you are a Dell fan and need a powerful device that looks much premium and is more portable, go for the XPS series.

Model: The Dell Latitude 7400-8N6DH is a business laptop hailing from the United States multinational computer technology company built with the vision of empowering productivity through an assortment of quirks that are guaranteed to function in accordance to one’s convenience. It is featured to be Dell’s smallest premium business-class laptop to this date. Improved connectivity enables users to automatically connect to the fastest Wi-Fi signal within their immediate proximity. The Dell Latitude 7400-8N6DH makes a strong impression through its smarter and lighter overall design. With the rise of awareness when it comes to environmental consciousness from around the globe, the Dell Latitude 7400-8N6DH makes its support towards the global movement resoundingly clear through its new angled design alone. The new angled design which serves as the blueprint in its production reduces the footprint by more than 6 % from previous Dell Latitude generation. This new angled design is the very reason that the Dell Latitude 7400-8N6DH can achieve a compact size of 14 inch in measurement. Apart from that, the Dell Latitude 7400-8N6DH is also assisting in the preservation of the planet by using water-based paints in order to reduce VOC emissions.

Privacy concerns can always be a major issue when navigating through the web on any technological device. Dell makes an effort to put user’s mind at ease through the introduction of several security features in both physical and virtual forms. For instance, Dell mimics the smart and intuitive design of the ThinkShutter mechanism by Lenovo and introduces their own rendition of a camera shutter. The Dell Latitude 7400-8N6DH also introduces a new security feature aptly named as the SafeScreen. The SafeScreen feature takes safeguarding concerns one step further by functioning as both a dynamic privacy panel option that provides better power efficiency as well as a contrast ratio to prevent people from peeping whatever is displayed on the screen. Not only that, the Dell Latitude 7400-8N6DH promotes a seamless sign-on experience through the integration of the SafeID technology. SafeID protects end users credentials and information with an optional biometric fingerprint reader inlaid on the power button. The Smart Card reader works in tandem with this fingerprint reading measure shielding electronic processes such as personal identification, access control, authentication and etc from leakage of confidential information. The ExpressConnect feature undoubtedly requires further elaboration as to the nature of how it functions in terms of securing the fastest Wi-Fi signal possible. The Dell Latitude 7400-8N6DH has a built-in 4x4 dynamic antenna tuning solution inside of its body and it is capable of providing reliable mobile broadband, especially in weak signal areas. The antennas function as receptors, which attract signal coverage, and has been tested to result in 70 % faster Internet connection speed.

Intel UHD Graphics 620: Integrated GPU (GT2, 24 EUs) found on some Kaby-Lake-Refresh CPU models (15 W ULV series). Technically identical to the previous Kaby-Lake GPU called HD Graphics 620.

Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards.

» Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.

Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.  

i7-8665U: Whiskey Lake based low power quad-core processor (technically identical to Kaby Lake but produced in a further improved 14nm++ process). The four cores are clocked between 1.9 and 4.8 GHz (Turbo Boost) and support HyperThreading.» Further information can be found in our Comparison of Mobile Processsors.


Above all, this display size is used for subnotebooks, ultrabooks and convertibles. For all three types, this size is quite large. The biggest variety of subnotebooks is represented with this size.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

» To find out how fine a display is, see our DPI List.

1.535 kg:

This weight is typical for very big tablets, subnotebooks, ultrabooks and convertibles with a 11-13 inch display-diagonal.

Dell: Dell Inc. is a multinational technology corporation that develops, manufactures, sells, and supports personal computers and other computer-related products. Based in Texas, Dell employs more than 82,700 people worldwide (2009). In 2006, Dell purchased the computer hardware manufacturer Alienware.

In 2014, the global market share of Dell laptops was 12.3% and it is 14% in 2016.

76.8%: This rating is not convincing. The laptop is evaluated below average, this is not really a recommendation for purchase.
