When comparing the Dell Inspiron 14 5420 and the Lenovo LOQ 15, consider the following: The Dell Inspiron has a more compact and lighter design, which makes it more portable; however, it offers a less powerful Nvidia MX570 graphics card compared to the Lenovo's more capable Nvidia RTX 4050, which is better for demanding visual work or gaming. The Dell's screen has a higher resolution, which can give crisper visuals for media and productivity, yet the Lenovo has a larger display and a much higher refresh rate ideal for smoother gameplay. The Dell runs on an Intel processor and Windows 11 Pro, while the Lenovo uses an AMD processor with Windows 11 Home, which might have implications for specific software preferences. The Lenovo also brings extra gaming features like a higher refresh rate and a newer release date, indicating more up-to-date hardware. In terms of weight and size, the Dell is more travel-friendly, but if performance, especially in graphics-intensive tasks, is a priority, the Lenovo is the stronger choice. Give Feedback

"If laptops were food, then the Dell Inspiron 14 5420 is arguably a Big Mac. There are cheaper and more expensive options, but this arguably represents the baseline of quality and value in the world of mobile computing… something that’s underlined by the attractive $1,279 price tag."

"Even after a short time with the LOQ 15, you'll find it has a lot going for it, but ultimately it's just "good"—not quite a star. The performance is respectable for the hardware it’s running, but Lenovo had to make some design sacrifices to trim the price. One of the better aspects is the keyboard, making it one of the better low-cost gaming laptops to actually put your hands on."
