The Dell G15 5520 is a good fit for you if high performance for activities like gaming, 3D modeling, or machine learning is a priority, as it has a more powerful GPU. However, it's heavier and has a shorter battery life, which makes it less portable. On the other hand, the Dell Inspiron 14 7435 offers greater portability due to its lighter weight and longer battery life, and it has a touchscreen with a higher resolution that may be preferred for general use or productivity tasks. If budget is a concern, the Inspiron 14 is usually less expensive, but with reduced performance for intensive tasks compared to the G15. Give Feedback

The Dell G15 5520 is good for gaming and AI, while the Dell Inpsiron 14 7435 is only fair.
Due to technical limitations, I am unable to access the document that contains the specific details on the Dell G15 5520 and the Dell Inspiron 14 7435 laptops. However, I can provide a general explanation for the differences based on the typical specifications for such laptops.
Gaming and 3D applications demand powerful graphics processing units (GPUs) and high screen refresh rates for smooth visuals, which are very important factors for performance. The Dell G15 5520 likely has a higher-end GPU and a faster screen refresh rate compared to the Dell Inspiron 14 7435, which would make it more suitable for gaming and 3D tasks, offering better performance in graphics-intensive applications. While the CPU and screen quality, being somewhat important, also influence performance and visual experience, it's typically the GPU and refresh rate that most directly impact a laptop's ability to handle gaming and 3D applications effectively.

The Dell G15 5520 has a better screen than the Dell Inpsiron 14 7435 for general use, gaming and AI, engineering and design, and content creation.
The Dell G15 5520 offers a high-resolution display with good brightness, enhancing visibility and clarity for general tasks and detailed engineering work, but its modest refresh rate falls short for the fast-paced visual requirements of gaming and 3D rendering. On the other hand, the Dell Inspiron 14 7435 provides a balance suitable for daily activities and some technical applications, with its resolution and brightness being adequate, but not exceptional, for both scenarios; however, it lacks in color accuracy for professional design tasks. Neither model excels in 3D environments due to lower refresh rates, making fast-moving images less smooth compared to displays optimized for gaming.

Olivier Martin, Ryan Lim, and John Peroramas | April 2023
"The Dell G15 (2022) is a 15.6-inch budget gaming laptop, and is great for gaming. You can configure the laptop with powerful Intel 12th Gen. CPUs and various NVIDIA dedicated GPUs, all of which deliver a smooth gaming experience at 1080p. There's also a QHD 240Hz display option if you want better visuals, though you'll have to pair it with the top-end NVIDIA GeForce RTX 3070 Ti to get good frame rates. It doesn't get overly hot or loud under load, and there's no noticeable throttling on the CPU or GPU. Unfortunately, the 120Hz panel has a slow response time, causing noticeable ghosting, and it doesn't support variable refresh rate."

"We see no shame in an economy laptop missing the four-star mark. Frankly, we considered giving the Inspiron 14 2-in-1 three-and-a-half stars for its low price, competitive performance, and long battery life. Unfortunately, working with a screen that can't deliver at least 300 nits of brightness is simply no fun to the point of detrimental. Still, if you're looking for a convertible laptop on a tight budget, it's worth keeping an eye on Dell's sales and discounts. That Lavender Blue model is fairly tempting."
