The ASUS ROG Strix G15, being more expensive, offers powerful performance suited for gaming and intensive tasks due to its high-end processor and dedicated graphics card and is optimized for intensive engineering applications. However, it has a shorter battery life and is a bit heavier, making it less portable. On the other hand, the Dell Inspiron 16 5620 is more budget-friendly and lighter, with a longer battery life, making it more portable and better suited for general use and everyday productivity; though it may not handle demanding engineering software or gaming as well as the ASUS. Both laptops have similar screen sizes, good build quality, and come equipped with Windows and backlit keyboards, but the ASUS edges ahead with better graphics performance. Give Feedback

The ASUS ROG Strix G15 and Dell Inspiron 16 5620 are both good for engineering and design, though the ASUS ROG Strix G15 is somewhat better.
The ASUS ROG Strix G15 boasts a high-performance AMD Ryzen 9 CPU and Nvidia RTX 3050 Ti GPU, which are ideal for demanding engineering software and design tasks, but it is heavier and has a shorter battery life. In contrast, the Dell Inspiron 16 5620 has an Intel i5 CPU with integrated Iris Xe graphics, which, although less powerful, offers a lighter design with a longer-lasting battery and a larger 16:10 screen that could benefit design work requiring more vertical screen space.

The ASUS ROG Strix G15 has a better screen than the Dell Inspiron 16 5620 for general use, gaming and AI, and engineering and design, while the Dell Inspiron 16 5620 has a better screen for content creation.
The ASUS ROG Strix G15, with its higher resolution and brightness, offers clearer and more vibrant visuals for everyday tasks and detailed engineering work, but its lower refresh rate hinders the smoothness needed for immersive gaming and 3D applications. On the other hand, the Dell Inspiron 16 5620 provides adequate display performance for both general use and technical tasks thanks to respectable resolution and color accuracy, but like the ASUS, it falls short for gaming due to a lackluster refresh rate. For both, the lack of a high refresh rate means gamers and 3D designers won't experience the fluid motion that's crucial for their applications.

Marius Schell | February 2021
"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."

"If the world is exciting enough right now, you can do far worse than a solid performer that you know will get the job done. Our review model is as powerful as you'd want an office machine to be unless you're performing specialist tasks and the price point is pretty attractive (unless work will let you have a MacBook Air instead)."
