We can spend all day talking about the ton of features this device offers in its numerous configurations. It comes with an optional fingerprint reader, IR face recognition scanner, proximity sensor, 1080p Web camera, LTE support, and more. And this is great, don’t get us wrong. However, what is more, important to us, is to get an adequate base. Some might say, it’s au naturel. In our opinion, this is a great machine. At least from this perspective. It has a great performance for this type of product. It sustains 30W of TDP for long periods of time and can boost pretty high too. The cooling solution it is equipped with, does a great job of cooling the internals, without having a negative impact on comfort, both in terms of noise, and keyboard temperature. Dell Latitude 14 5431’s IPS panel has a Full HD resolution, comfortable viewing angles, and a good contrast ratio. Thankfully, its backlight doesn’t use PWM for brightness adjustment. On the other hand, the screen covers only 50% of the sRGB colors, which has two impacts. One – the image looks a bit dull, when compared to a full-coverage panel, and two – you can’t expect accurate colors. Be wary of a 768p TN display option, which is something you want to stay away from. On the bright side, you can pick a panel with full sRGB coverage, which will be ideal for color-related work. Furthermore, you get two SODIMM slots for memory expansion, which is not usual for 14-inch notebooks. But yet again, this is not an ordinary device. It is a business outfit, which provides more than you might need. What you really need, however, is long battery life. In this case, the 64Wh battery lasts for more than 13 hours of Web browsing, or about 9 hours of video playback. This way, it is almost sure that you will be able to get an entire workday on battery power. On the other hand, using more demanding software will obliterate the package quite quickly. Another aspect we really like is the port selection. Two Thunderbolt ports are joined by a couple of USB Type-As, a MicroSD card reader, an HDMI connector, and a LAN port. This makes it a strong opponent even to the boldest of Fujitsus out there.

The Dell Latitude 5450 is a snappy small office device that surprises us with its performance. Despite the modest-looking thermal system with just one fan and a single heat pipe, the Core Ultra 7 155U can sustain higher clocks in medium and long loads than the bigger Latitude 5550 with the same chip. Expectedly, the fan here is more audible but it’s not noisy. The keyboard is also warmer to the touch than the one of the 5550 version but it’s not scorching hot so we can call it a day. The battery life with the same 54Wh capacity is similar to the bigger “cousin” – around 9 hours of videos. Even the port selection is near equivalent – two Thunderbolt 4s and a pair of Type As (but the 14-incher doesn’t offer a MicroSD slot).

戴尔 Latitude 5450 是一款灵敏的小型办公设备，它的性能给我们带来了惊喜。尽管只有一个风扇和一根热管的散热系统看起来并不起眼，但酷睿超 7 155U 在中长期负载下仍能维持比采用相同芯片的大型 Latitude 5550 更高的时钟频率。可以预料的是，这里的风扇声音更大，但并不嘈杂。键盘的触感也比 5550 版本的键盘要热一些，但并不烫手，所以我们可以就此打住。电池容量同样为 54 瓦时，续航时间与更大的 “表亲 “相似–大约可播放 9 小时视频。就连端口选择也几乎相当–两个 Thunderbolt 4 和一对 Type As（但 14 英寸机型不提供 MicroSD 插槽）。您仍然可以获得两个 SODIMM 插槽，但存储空间受限，只有一个 2230 NVMe 硬盘插槽。如果你不是太自命不凡，1080p 60Hz IPS 面板（LG Display RNTRJ-140WFH (LGD0753)）就能满足你的需求。该屏幕不采用 PWM 技术，视角宽广，满足正常办公的所有需求。该面板的缺点是色彩覆盖面窄、最大亮度低。Latitude 5450 的紧凑尺寸、高性能、无 PWM 面板和漂亮的键盘给人留下了深刻印象。
Positive: Silent system; solid workmanship; comfortable keyboard; long battery life; nice webcam; fast fingerprint sensor; powerful processor. Negative: Overheats while using; poor display.

If you are purely a business user and got this laptop from your employer, you shouldn’t have any real complaints. What the device has going for it is very good build quality, a very good keyboard for typing content, an anti-glare display that works well in different lighting conditions, decent overall performance, and a day-long battery life. It is also really lightweight and comfortable to carry/use for long durations. Where it falters is that Windows on ARM still has bugs to iron out, and that’s more of a Qualcomm-Microsoft thing to fix. However, there are laptops in a similar price range that offer better battery life, and my biggest gripe is the lack of an HDMI port. For an asking price of Rs 1,19,950 + taxes for the configuration I have, it is a tad steep, especially if you compare it with Dell’s own lineup as well as the competition’s “non-business” laptop lineup. Then again, they wouldn’t come with Dell’s security features such as Dell SafeID and Secure BIOS, which is a big factor for business users.

For gaming enthusiasts, Dell's Alienware brand is for gaming notebooks.
Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards.
Intel Iris Xe G7 96EUs: Integrated graphics card in Intel Tiger Lake G4 SoCs based on the new Gen. 12 architecture with 96 EUs (Execution Units / Shader Cluster). The clock rate depends on the processor model. The Tiger Lake chips are produced in the modern 10nm+ process at Intel.
Intel Graphics 4-Core: Integrated graphics card based on the Xe LPG architecture (similar to the dedicated Arc GPUs, but with a focus on efficiency). Provides 4 Xe cores (64 Xe vector engines) and 4 ray tracing units.
Qualcomm Adreno X1-45 1.7 TFLOPS: An integrated graphics adapter that the Snapdragon X Plus 8-core X1P-42-100 SoC features. Compared to the faster 3.8 TFLOPS and 4.6 TFLOPS X1-85 iGPUs, this one does not just run at lower clock speeds but also has fewer unified shaders at its disposal, with 768 being the most likely number. The underlying architecture is reportedly not much different from what was used in the Adreno 730. As for its gaming performance, it's only just sufficient for pre-2020 games at resolutions such as HD 720p on low graphics settings.

14.00:
14 inch display size represents a middle ground between the small subnotebook formats and the screens of the standard 15 inch laptops.
The reason for the popularity of mid-sized displays is that this size is reasonably easy on the eyes, provides good resolutions with usable detail sizes, yet does not consume too much power and the devices can still be reasonably compact.
In the past, 14-inch devices were very rare, but now they are the standard for laptops after the 15-inchers.

75%: This rating is poor. More than three quarters of the models are rated better. That is rather not a purchase recommendation. Even if verbal ratings in this area do not sound that bad ("sufficient" or "satisfactory"), they are usually euphemisms that disguise a classification as a below-average laptop.
