The ASUS ROG Strix G18 is a high-performance laptop with a larger screen and higher refresh rate, making it suitable for gaming and intensive engineering work, but it is heavier and has a shorter battery life, making it less portable. On the other hand, the Lenovo ThinkPad Z13 offers portability with its lighter weight and longer battery life, as well as a touchscreen, and is designed as a premium business laptop, but it has a smaller screen with a lower refresh rate and may not handle intensive graphics tasks or gaming as well as the ASUS. If top-tier gaming and engineering capabilities are needed and portability is less of a concern, the ASUS could be the preferred choice, whereas for business purposes, daily carry, and general use, the Lenovo could be the more convenient option.

The ASUS ROG Strix G18 is very good for gaming and AI, while the Lenovo ThinkPad Z13 is only fair.
The ASUS ROG Strix G18 surpasses the Lenovo ThinkPad Z13 for gaming and 3D due to its significantly more powerful Nvidia RTX 4070 GPU and a much higher screen refresh rate, enhancing fluidity and detail in games and 3D applications. Conversely, the ThinkPad Z13, with its AMD Radeon 680M GPU and standard refresh rate, provides a level of performance that is adequate for less demanding gaming and 3D tasks but falls short for intense graphics needs.

The ASUS ROG Strix G18 has a better screen than the Lenovo ThinkPad Z13 for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, the ASUS and Lenovo both provide sharp, clear displays, but the ASUS might be preferred for its potentially higher resolution and brightness. Engineers and designers will appreciate the accurate color representation on both laptops, yet the ASUS may have a slight edge if it covers a wider range of color gamuts. However, gamers looking for smooth visuals in fast-paced games will find both lacking due to their lower refresh rates, making them less ideal for 3D gaming where fluid motion is key.

Florian Glaser | March 2023
"With the ROG Strix G18, Asus has made an almost consistently good debut in the still quite new 18-inch laptop segment. The base unit case shows a few signs of weakness in the area of stability and is something which has an effect on the perceived quality of the input devices (the chassis tends to rattle a bit). Nevertheless, thanks to generous port features (incl. Thunderbolt 4), a striking design, and extensive lighting (keyboard, LED strip on the front), gamers get a fitting gaming platform."

"In the premium ultraportable space, the Lenovo ThinkPad Z13 competes with the best of the best, and still manages to shine. The design is an impressive departure from the bland bare-metal laptop that's become so popular in recent years, and the AMD-powered system has performance that's just as impressive. It's a stark alternative to the Intel-based majority, and it stands up well enough to the impressive Apple M2 processor."
