The ASUS ROG Strix G15 leans more toward gaming and performance-heavy tasks with a high refresh rate screen and a more capable dedicated graphics card. In contrast, the LG Gram 16 prioritizes portability and long battery life, with a lightweight design and a larger, higher-resolution screen that's great for productivity and media consumption. The Strix has a slightly better overall performance for engineering and 3D tasks, while the Gram offers a quieter, cooler, fanless operation. If gaming or performance-intensive applications are your main focus, the ASUS might suit you, but for travel and longer working sessions, the LG Gram could be more convenient. Give Feedback

The ASUS ROG Strix G15 has a better screen than the LG Gram 16 for gaming and AI, while the LG Gram 16 has a better screen for general use, engineering and design, and content creation.
For general use, the ASUS ROG Strix G15 and LG Gram 16 both offer screens that are bright, have high resolution, and use panel types that provide clear and vivid image quality, making for a pleasant viewing experience in everyday tasks. When it comes to engineering and design, both laptops have displays that cover a broad range of colors, vital for accurately rendering designs, but their lower color gamut coverage compared to industry-leading screens might not satisfy professionals who need the utmost color precision. However, for gaming and 3D applications, their lower refresh rates detract from the smoothness and responsiveness critical in these scenarios, potentially making them less ideal for hardcore gamers or professionals in animation and real-time 3D modeling.

How the ASUS ROG Strix G15 and the LG Gram 16 compare to other laptops
"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 LG Gram 16 is a lightweight device with stability issues. The LG Gram 16Z90Q with a Core i7-1260P is made with portability in mind and places less of a focus on users with high demands on performance. The compact and light chassis is particularly practical when you are on the go. The device is not only comfortably small and lightweight, it also boasts a great battery life. When connected to mains, on the other hand, the 16-inch device is rather disappointing. The standard cooling mode causes extreme volatility in terms of CPU, SSD and iGPU performance. The meager stability of the chassis may also put off some potential buyers."
