When considering the Asus ROG Strix G15 and the Lenovo ThinkPad X13, remember the Asus typically offers superior performance for gaming and intensive tasks due to its powerful graphics and processing capabilities but tends to be heavier and have a shorter battery life, making it less ideal for frequent travel. The Lenovo ThinkPad X13, while typically more affordable and offering better portability and battery life, is better suited for general use and business applications but may not handle demanding graphics tasks as well. Choose the Asus if gaming or performance is a priority, or the Lenovo for a balance of cost, mobility, and battery for everyday tasks. Give Feedback

The ASUS ROG Strix G15 typically offers a high-end CPU, ample RAM, and a powerful GPU, which are excellent for demanding tasks in engineering and design, plus it often comes with a high-quality screen for precise visual work; however, it's less portable due to its size and weight.

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 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."
