The Dell Inspiron 15 3511 is more affordable and provides a larger 15.6-inch screen which is great for productivity and media consumption, but is heavier and has a generally lower battery life. In contrast, the Razer Book 13 is more expensive, offers a more compact 13.4-inch display with a higher resolution and superior color, and it's lighter, making it ideal for portability. The Razer also has a more powerful processor for demanding tasks and potentially better build quality. Choose the Dell for budget-friendliness and a larger screen, or the Razer for enhanced portability, performance, and display quality. Give Feedback

The Razer Book 13 has a better screen than the Dell Inspiron 15 3511 for general use, gaming and AI, engineering and design, and content creation.
If you prioritize vibrant displays and accurate colors for tasks like photo editing or engineering design, the Razer Book 13 delivers superior visuals with its high-resolution screen and coverage of color gamuts. However, for fast-paced gaming or 3D modeling, neither laptop is ideal due to their lower refresh rates, which could lead to less smooth visuals. The Dell Inspiron is a more budget-friendly option for everyday tasks, offering satisfactory display quality, but it falls short in color accuracy and resolution compared to the Razer Book 13.

The Dell Inspiron 15 3511 and Razer Book 13 are both good for general use.
The Dell Inspiron 15 3511, with its ample RAM and large screen, is suited for general use where multitasking and screen real estate are valued, but its bulk and moderate battery life make it less portable. The Razer Book 13, while more portable with a higher battery life and a smaller, sharper display that's touch-enabled, offers less storage and RAM, making it a premium choice for mobility over extensive storage capacity and multitasking prowess.

The Razer Book 13 and Dell Inspiron 15 3511 are both only fair for gaming and AI.
The Dell Inspiron 15 3511 and Razer Book 13 are considered fair for gaming and 3D because both utilize integrated graphics with comparable performance, specifically the Intel Iris Xe in an i5 for the Dell and an i7 for the Razer, neither of which match the power of dedicated gaming GPUs. Additionally, while both have 60Hz screen refresh rates which are adequate for casual gaming, they do not offer the higher refresh rates preferred for competitive gaming, and their CPUs and screen quality, although reasonable, are not top-of-the-line for these activities.

Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

"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."
