The ASUS ROG Flow X16 offers higher performance, with a potent AMD processor and Nvidia graphics, suitable for demanding tasks like gaming, 3D modeling, or machine learning. It's a 2-in-1 convertible, allowing it to double as a tablet, and sports a higher-resolution touch display. However, it's heavier and less portable compared to the Dell Latitude 14 7490. The Dell Latitude is more affordable, with modest performance catered to general use, like office work or web browsing, thanks to its Intel processor and integrated graphics. It is also lighter and better in terms of battery life, making it ideal for users who prioritize portability and battery life over high-end performance. Give Feedback

The ASUS ROG Flow X16 has a better screen than the Dell Latitude 14 7490 for general use, gaming and AI, engineering and design, software development, and content creation.
If you need exceptional visual fidelity for tasks like photo editing or graphical work, the ASUS with its superior color accuracy will be a better fit, but keep in mind it's not optimal for fast-paced gaming due to its lower refresh rate. The Dell, with fair overall screen traits, offers a good balance for everyday tasks and engineering software that might not demand the highest color range or brightness, but won't stand up to the needs of gaming or high-frame-rate 3D applications. Ultimately, you'll want to weigh the importance of color precision and screen brightness for your professional tasks against the need for smooth visuals in gaming or animation when making your choice.

"Above all else, the Asus ROG Flow X16 is one thing - versatile! It is a thin, mobile work device, it's a 2-in-1, tablet, a powerful workstation and even a gaming PC. But something even more surprising: It does all of these things really well without making any big blunders. It's anything but a lazy compromise. Because, despite its compact dimensions and 2-in-1 functionality, the hardware isn't throttled and boasts, at least in turbo mode, above-average 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."
