The Dell Alienware X17 R2, while more expensive, is well-suited for intensive tasks like gaming, 3D rendering, and machine learning thanks to its powerful Intel i9 processor and Nvidia RTX 3080 Ti graphics card. With a larger display and high-end internals, it also offers an immersive experience but is heavier and less portable. On the other hand, the Dell Latitude 14 7490 is more budget-friendly and portable, making it a good fit for general use and business applications. Its Intel i7 processor and integrated graphics are capable for everyday tasks, but it won't handle demanding software as smoothly as the Alienware. Therefore, the Latitude is ideal if you prioritize portability and cost over high performance. Give Feedback

NotebookCheck

Allen Ngo | May 2022
"The Alienware x17 R2 recognizes targets a significantly higher TGP of 175 W for a roughly 30 percent performance boost over laptops running on the ~100 W GeForce RTX 3080 Ti like the Razer Blade 15 or Gigabyte Aero YE5. Similar results can be found through the CPU as well. This single aspect of the Alienware is perhaps the biggest differentiating factor between it and other ultrathin gaming laptops. Of course, the "performance at all cost" approach comes with drawbacks. Power consumption in particular is through the roof and battery life suffers because of it even when on the lowest performance settings."

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."
