The Dell G15 5520 offers strong performance for intensive tasks like gaming, 3D rendering, or engineering due to its powerful processor and dedicated graphics card, making it suitable for demanding applications but it is heavier and has shorter battery life, thus less portable. In contrast, the Lenovo IdeaPad 5 15" is generally less expensive and lighter with longer battery life, and features an integrated graphics chip that is suitable for general use and light workloads; it is highly portable but not ideal for graphics-intensive tasks. Choose the Dell if you need high performance for specialized tasks, and the Lenovo for cost efficiency and better portability in everyday use. Give Feedback

The Dell G15 5520 is good for gaming and AI, while the Lenovo IdeaPad 5 15" is only fair.
The Dell G15 5520 offers superior gaming and 3D performance due to its dedicated Nvidia RTX 3060 graphics card and a higher screen refresh rate, conducive to smoother visuals, while the Lenovo IdeaPad 5 uses an integrated GPU in the AMD Ryzen 7 processor with a lower refresh rate, resulting in less graphics processing power and potentially choppier gameplay.

The Dell G15 5520 has a better screen than the Lenovo IdeaPad 5 15" for general use, gaming and AI, engineering and design, and content creation.
The Dell G15 5520, with its higher resolution and brightness, provides a vibrant and sharp image that enhances the experience for general use and intricate tasks like engineering and design, where crisp visuals matter, but falls short in gaming due to a lower refresh rate which is crucial for fluid motion. The Lenovo IdeaPad 5, while offering acceptable clarity and brightness for everyday tasks and some design work, doesn't excel in any specific area due to its average color representation and might disappoint in high-paced gaming environments. For those involved in 3D work or intense gaming sessions, the lack of a high refresh rate on both models could be a significant drawback, as it prevents the smooth visual flow that such activities demand.

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."

"The Lenovo IdeaPad 5 is convincing due to its long battery life. The device scores points especially with its large battery and long battery runtimes combined with its low consumption. The CPU and GPU perform in the test as one would expect, and in line with what was familiar from the somewhat smaller 14-inch sister model, the Lenovo IdeaPad 5 14."
