The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the Dell Latitude 14 7490 is poor.
The Dell Latitude 14 7490's integrated Intel UHD Graphics 620 and standard 60Hz screen refresh rate limit gaming and 3D performance, while the Lenovo Legion Slim 7 is equipped with a more powerful Nvidia RTX 3060 GPU and a higher 165Hz refresh rate display, better suited for gaming and high frame rate applications.

The Lenovo Legion Slim 7 15.6" is 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 having an older generation CPU and integrated graphics, which are less powerful for tasks such as 3D modeling and simulations compared to the Lenovo Legion Slim 7's newer CPU and dedicated Nvidia graphics. Additionally, while both have high-quality IPS displays, the Legion Slim's screen is brighter and offers a higher refresh rate, which enhances the visual experience for design work, but it is heavier and less portable.

The Lenovo Legion Slim 7 has a better screen than the Dell Latitude 14 7490 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the Dell Latitude’s screen provides clarity and comfort for everyday tasks like browsing and document editing, while the Lenovo Legion’s higher resolution and brightness offer a more vibrant viewing experience. Engineering and design professionals will appreciate the Dell's good color accuracy for precision work, yet the Lenovo matches this with similar color gamut coverage, crucial for tasks such as photo editing or CAD work. However, for gaming and 3D applications where fluid motion is key, both laptops fall short due to lower refresh rates, which can lead to less smooth visuals compared to screens designed specifically for fast-paced games.

"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 Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
