When deciding between the Dell Latitude 14 7490 and the Razer Blade 18, consider that the Latitude is more budget-friendly and offers solid performance for general business usage and everyday tasks, along with good portability due to its lighter weight and smaller size. Conversely, the Razer Blade 18 is priced at a premium but delivers significant power with advanced components, making it suitable for demanding tasks like 3D, machine learning or gaming. However, it's heavier and has a larger screen size, making it less portable. The Razer's higher cost reflects its performance capabilities and suitability for specialized intensive tasks. If portability and budget are key concerns, go for the Dell; if you need top performance for specialized work and gaming, consider the Razer, keeping in mind its higher price and lower portability.

The Razer Blade 18 has a better screen than the Dell Latitude 14 7490 for general use, gaming and AI, engineering and design, content creation, and software development.
If you prioritize sharpness and clarity for everyday tasks, the Dell Latitude's fair screen quality provides a balance between performance and cost, though it may not offer the vibrant colors and wider viewing angles of more premium screens. For engineering and design, the Razer Blade's superior color coverage ensures that your projects look accurate and vivid, vital for detail-oriented work. However, for immersive gaming and seamless 3D modeling, neither offers the high refresh rates needed for smooth motion and gameplay, making them less ideal for these specific purposes.

"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."

"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
