The ASUS ROG Zephyrus G15 is the better performer for intensive engineering tasks, 3D rendering, machine learning, and gaming, thanks to its high-end processor and graphics card. However, it's heavier and has a shorter battery life compared to the LG Gram 16, which offers exceptional portability and a longer battery life, making it a good fit for general use and productivity on the go. The LG Gram 16 is also typically less expensive but is not suited for high-performance needs like gaming or engineering software. Both laptops have good screens and build quality, but the ASUS has a higher refresh rate for smoother visuals, which is important for fast-paced games. Give Feedback

"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 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."
