The Dell Latitude 14 7490 is a more budget-friendly option and serves well for general and business use with good portability and battery life. However, if you need superior performance for tasks like gaming, 3D applications, or machine learning, the Lenovo IdeaPad Gaming 3, while more expensive, offers a powerful graphics card and higher refresh rate screen but at the cost of being heavier and having shorter battery life. The Dell is also equipped with more RAM, which aids in multitasking, whereas the Lenovo comes with a newer processor and operating system. Consider your primary use case and whether the additional cost for gaming and performance capabilities is justified. Give Feedback

"The Dell Latitude 7490's got the speed you need (and then some), a keyboard that's comfortable enough for writing all day long and a battery that supports a full 8-hour workday. If only the display were brighter and it managed heat better. If you need every minute of battery life you can get, the extended-battery version of the Lenovo ThinkPad T480 lasts 8 hours longer than the Latitude 7490, but its display is much less colorful."

"The Lenovo IdeaPad Gaming 3 is one of the most powerful RTX 3050 Ti laptops. If you disregard the mediocre quality of the case in terms of the material and workmanship, Lenovo has created a successful budget gaming laptop with the IdeaPad Gaming. Thanks to high TDPs and constant performance development, the Core i5-12500H and GeForce RTX 3050 Ti are able to show their full power, while in contrast, the (mostly slower) competitors deliver a better battery life. However, hardly any of the alternative laptops are able to reach the image quality of the Gaming 3. Most of the competitors are left behind in terms of the color space and brightness."
