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

Henry T. Casey | April 2018
"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."
