If you prioritize a more budget-friendly option, the Dell Inspiron 16 5620 is significantly less expensive and offers a solid balance for everyday tasks and lightweight engineering work, though it wouldn't be ideal for intensive gaming or heavy 3D/machine learning tasks. On the other hand, the Razer Blade 18, while more expensive, is designed for high performance and could be excellent for gaming, 3D rendering, machine learning, and demanding engineering applications. However, the Razer Blade 18 is heavier, which impacts portability. Both laptops have a similar screen aspect ratio and neither has a touchscreen, but the Razer features a higher refresh rate which may be beneficial for fast-paced visual tasks. Give Feedback

The Razer Blade 18 has a better screen than the Dell Inspiron 16 5620 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Inspiron 16 5620's fair general use and engineering screen quality stems from an acceptable resolution and brightness, but it lacks the wide color gamut needed for high-end design work. The Razer Blade 18 shines with a very good quality display for both general use and professional design, largely due to its high resolution, brightness, and wide color coverage that satisfies demanding color accuracy needs. However, the poor 3D quality rating for both laptops suggests that they have lower refresh rates, which falls short for gaming and 3D applications where smooth motion is crucial.

"If the world is exciting enough right now, you can do far worse than a solid performer that you know will get the job done. Our review model is as powerful as you'd want an office machine to be unless you're performing specialist tasks and the price point is pretty attractive (unless work will let you have a MacBook Air instead)."

Matthew Buzzi | March 2023
"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."
