If your priority is longer battery life and a slightly more portable design with a more vibrant screen, the Razer Book 13 stands out; however, it's also more expensive than the Dell Inspiron 14 7420. The Dell has a slightly larger screen and is more affordable, but it offers a lower battery life and the screen isn't as bright or colorful. Both laptops have similar storage, RAM, and central processing units, making them capable for general use, but for intensive tasks such as 3D rendering, machine learning, or gaming, both may not be the optimal choice due to their integrated graphics units. If typing experience and build quality are important to you, the Razer Book again has the edge but expect to pay more for those incremental benefits. Give Feedback

The Razer Book 13 has a better screen than the Dell Inspiron 14 7420 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Inspiron 14 7420, with its fair screen quality, offers a balance of resolution and brightness suitable for everyday tasks and basic engineering, but its lower refresh rate and limited color gamut may not satisfy the demands of high-end gaming and professional design work. The Razer Book 13's good screen quality means higher resolution and brightness, enhancing both general use and design tasks with more accurate color representation thanks to its wider color gamut, yet it still falls short for gaming due to a refresh rate that's not high enough for optimum gaming performance. Therefore, while both laptops can serve well for casual use and professional design, neither is optimal for gaming or 3D applications where a fast refresh rate is crucial for smooth visuals.

The Razer Book 13 and Dell Inspiron 14 7420 are both only fair for gaming and AI.
The Dell Inspiron 14 7420 and the Razer Book 13 are considered fair for gaming and 3D tasks primarily because they both have integrated GPUs, which are less powerful than dedicated gaming graphics cards, and their screens have a typical refresh rate of 60Hz which is not ideal for high-frame-rate gaming. Additionally, while both have capable CPUs and high-quality screens, these components are not as crucial as the GPU and refresh rate for gaming performance.

"Notable qualities of the Inspiron 7420 2-in-1 include the 16:10 aspect ratio, strong hinges, 12th gen Intel CPU with optional GeForce MX graphics, and easy serviceability. Such features would typically cost hundreds of dollars more on higher-end alternatives from competing manufacturers. The value proposition is therefore relatively high for users looking to maximize bang for the buck."

"The Razer Book is like an XPS 13, but faster. The Book 13 combines the design philosophy and performance of a Blade Stealth with the 16:10 display of a Dell XPS 13 for an impressive piece of hardware. Office users who want something more stylish than the typical Dell, HP or Lenovo will certainly find themselves drawn to this Razer subnotebook. If your priorities are to have the best-looking and fastest 13-inch laptop in the office over auxiliary features, however, then the Book 13 proudly fulfills that niche."
