If you’re looking for a more budget-friendly laptop for everyday tasks, the Dell Inspiron 15 3511 offers a balance between cost and capability, being less expensive with sufficient performance for general use. However, if high performance is key, especially for gaming, 3D rendering, or machine learning, the more expensive Razer Blade 18 is equipped with a significantly more powerful processor and graphics suitable for these tasks. The Razer Blade 18's large display with a higher refresh rate also provides a superior visual experience. The trade-off with the Razer comes in the form of reduced battery life and increased weight, making it less portable than the Dell Inspiron. Give Feedback

The Razer Blade 18 is very good for gaming and AI, while the Dell Inspiron 15 3511 is only fair.
The Dell Inspiron 15 3511 is fair for gaming and 3D because it uses an integrated Intel Iris Xe GPU, which is less powerful, and has a standard 60Hz screen refresh rate. The Razer Blade 18 excels due to its dedicated Nvidia RTX 4070 GPU which is significantly stronger for these tasks and offers a much higher 240Hz screen refresh rate, enhancing fluidity and responsiveness in games and 3D applications.

The Razer Blade 18 is excellent for engineering and design, while the Dell Inspiron 15 3511 is good.
The Razer Blade 18 surpasses the Dell Inspiron 15 3511 in engineering and design use due to its more powerful CPU and GPU, higher resolution and brighter screen, which caters to intensive tasks and visual accuracy. However, the Razer Blade 18 is less portable due to being heavier and having a larger screen, which could make it less convenient for on-the-go use compared to the lighter and more compact Dell Inspiron 15 3511.

The Razer Blade 18 has a better screen than the Dell Inspiron 15 3511 for general use, gaming and AI, engineering and design, content creation, and software development.
When considering screen quality, the Dell Inspiron 15 3511's display offers adequate resolution and brightness for browsing, document editing, and media consumption, which suffices for general tasks. However, the Razer Blade 18’s screen stands out with superior resolution and brightness, enhancing the visual experience for detailed work in engineering and design through richer colors and sharper images due to its higher color gamut coverage. Yet, for Gaming and 3D applications where smooth motion is key, both laptops fall short because they lack high refresh rates, which are crucial for fluid motion and reducing motion blur during fast-paced activities.

"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."

"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."
