The Dell Latitude 14 7490 offers a larger solid-state drive and more memory, potentially making it a better fit if you need storage space and multitasking ability, which could benefit intensive tasks. It is powered by an Intel i7 processor with integrated graphics, making it suitable for general use and less graphical engineering tasks. On the other hand, the Lenovo IdeaPad 3 14" has a newer AMD Ryzen processor with better integrated graphics, which might be preferable for light 3D applications and media enjoyment. It comes with a smaller solid-state drive and less memory, which might be less optimal for heavy workloads but may suffice for everyday tasks. The Lenovo also runs on the newer Windows 11, whereas the Dell comes with Windows 10 Pro. Give Feedback

The Dell Latitude 14 7490 has a better screen than the Lenovo IdeaPad 3 14" for general use, engineering and design, and content creation.
For general use, the Dell Latitude's better resolution and brightness offer clearer and more vibrant visuals than the Lenovo IdeaPad, making it more suitable for everyday tasks that involve reading text or viewing images. The Dell's screen can display a wider range of colors, which is critical for engineering and design applications where precision in color representation is key. However, for gaming and 3D applications, the lower refresh rate of the Dell Latitude's display compared to what gamers usually seek means a less smooth visual experience, while the Lenovo IdeaPad faces similar challenges but also lacks the higher color accuracy of the Dell.

Although they have very similar scores, PerfectRec considers Lenovo IdeaPad 3 14" to be only fair for gaming and AI, while the Dell Latitude 14 7490 is poor.
The Dell Latitude 14 7490 and the Lenovo IdeaPad 3 14" are both equipped with integrated graphics—Intel UHD Graphics 620 and AMD Vega 7 respectively—which are less powerful than dedicated gaming GPUs, limiting their capability for gaming and 3D tasks. Furthermore, both have the same screen refresh rate of 60Hz, which is lower than the higher rates preferred in gaming for smoother visuals, and while their CPUs and screen qualities are adequate, they don't compensate for the GPU and refresh rate limitations for gaming and 3D performance.

The Dell Latitude 14 7490 and Lenovo IdeaPad 3 14" are both only fair for engineering and design.
The Dell Latitude 14 7490 with its higher RAM, superior CPU, and greater storage is more capable for engineering tasks than the Lenovo IdeaPad 3, although both have fair performance due to their integrated graphics which limit design capabilities, and comparable screen quality. While the Dell has a slightly larger battery and better ports, making it better for extended work sessions, the Lenovo shines in portability and quieter operation, important for mobile usage and work environments where noise is a concern.

How the Dell Latitude 14 7490 and the Lenovo IdeaPad 3 14" compare to other laptops
"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 low-priced IdeaPad 3 14 delivers on core functionality. Lenovo's IdeaPad 3 14 meets all the basic requirements for an inexpensive office laptop. The matte IPS display is bright enough, the performance is high for the class, and the input devices are rock solid. In addition, the mostly quiet operation including the useful performance modes, cool surface temperatures, easy maintainability as well as expandable working and mass storage all contribute to the IdeaPad 3 14's value proposition."
