The ASUS ROG Strix G15 offers a balance between price and performance, especially for general use and gaming, with its AMD Ryzen 9 processor and Nvidia RTX 3050 Ti graphics. It's slightly more portable and provides a decent battery life. On the other hand, the Lenovo Legion 5i Pro boasts a more powerful Intel i7 processor and Nvidia RTX 4060 graphics, making it better suited for intensive 3D rendering, machine learning, and engineering tasks. The Legion also has a larger and higher resolution display which offers better color accuracy, but it’s heavier and has a lower battery life, making it less portable. Give Feedback

The Lenovo Legion Pro 5i is very good for engineering and design, while the ASUS ROG Strix G15 is good.
The Lenovo Legion 5i Pro is rated higher for engineering and design use largely because it features a more powerful GPU and a higher resolution screen with better color coverage, which are critical for design tasks and engineering simulations. Meanwhile, the ASUS ROG Strix G15, while still competent, has a less powerful GPU and lower screen resolution, aspects that are less suited for highly demanding design work.

The Lenovo Legion Pro 5i has a better screen than the ASUS ROG Strix G15 for general use, gaming and AI, engineering and design, and content creation.
For general use, the Lenovo Legion Pro 5i stands out with higher resolution and brightness, which results in clearer and more vivid visuals, while the ASUS ROG Strix G15 has adequate quality but it may not be as sharp or bright. When considering engineering and design tasks, the Lenovo likely has better color accuracy and range, essential for precise color work, whereas the ASUS might not reproduce the same level of detail within color gamuts. However, both the ASUS and Lenovo have screens that aren't ideal for 3D tasks or gaming, as they lack the high refresh rates needed for smooth motion rendering, although they may be sufficient for less demanding visual work.

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."

"The midpriced Lenovo Legion Pro 5i Gen 8 follows some of our favorite gaming machines, including last year's model and the higher-end Legion Pro 7i Gen 8 tested earlier this year. But pedigree doesn't count for much in the computer world, and gaming laptops require a certain level of power and graphics performance to justify their prices. The Pro 5i Gen 8 just doesn't do that, offering middling CPU and GPU performance rather than the sort of muscle that would make it a great value."
