When deciding between the ASUS ROG Zephyrus G15 and the Lenovo ThinkPad X13, consider that the ASUS is tailored for high-performance tasks like gaming, 3D modelling, and video editing due to its robust hardware, but it's less portable and usually has a shorter battery life. If portability and battery duration are priorities, and you primarily engage in general computing tasks, the Lenovo might be a better choice. The ThinkPad also traditionally offers a more business-oriented design with durability and enterprise features. However, its performance in resource-heavy applications won't match that of the ASUS. Choose the ThinkPad for work and travel, or the ASUS for demanding multimedia tasks and gaming. Give Feedback

The ASUS ROG Zephyrus G15 has a better screen than the Lenovo ThinkPad X13 for general use, gaming and AI, and engineering and design, while the Lenovo ThinkPad X13 has a better screen for content creation.
For general use, you'll appreciate the ASUS ROG Zephyrus G15's high-resolution, bright display that makes text and images crisp and vibrant, but its refresh rate isn't as high as gaming-specific models, which could disappoint gamers looking for fluid motion. The Lenovo ThinkPad X13 also offers a good quality screen with solid brightness and resolution, but like the ASUS, it's not optimized for gaming, meaning it lacks the high refresh rate that's crucial for fast-paced action. Both laptops can handle engineering and design tasks well with wide color gamuts for precise color work, but designers focused on 3D applications might find the lower refresh rates limiting.

"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."

"The Lenovo ThinkPad X13 G4 has very good input devices, a wide array of security features and ports as well as 5G in the tested configuration. It is more compact and lightweight compared with its predecessor, and it has improved speakers and a slightly better webcam. On the other hand, the fan is more annoying and the performance is barely improved. The battery is worse as well, but this is primarily attributable to the OLED screen - if this aspect is important, buyers should choose the IPS Low Power LCD."
