If you're prioritizing cost savings and need a laptop for everyday tasks like browsing and office work, the Dell Latitude 14 7490 offers affordability and sufficient performance for general use with the added benefit of being lighter and more portable, which is great if you move around a lot. However, if your focus is on high-end gaming, 3D rendering, or machine learning tasks, the Lenovo Legion 7, while more expensive, provides significantly better performance, a more powerful graphics card, and a stronger cooling system, which are essential for those activities, but it's also heavier which makes it less portable. Keep in mind that with the Lenovo, you may also get a better screen and sound for multimedia purposes, but at the cost of shorter battery life compared to the Dell. Give Feedback

The Lenovo Legion 7 is very good for engineering and design, while the Dell Latitude 14 7490 is only fair.
The Dell Latitude 14 7490 is considered fair for engineering and design due to its older generation Intel i7 processor and integrated Intel UHD Graphics, making it less suited for demanding graphics and computational tasks compared to the Lenovo Legion 7, which features a more powerful AMD Ryzen 7 processor and Nvidia RTX 3070 graphics card, providing very good performance for engineering applications that require intensive computing and high-quality visuals. The Dell, however, is lighter and more portable with longer battery life, which may be beneficial for users who prioritize mobility and off-charger work time over raw performance.

"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 Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."
