The ASUS ROG Strix G15 is tailored for gaming, with higher performance suitable for 3D, machine learning tasks, and an emphasis on fast motion thanks to its superior GPU and higher-refresh-rate screen. However, it is heavier and less portable, making it less convenient if mobility is important. The LG Ultra 13, in contrast, is lighter and highly portable with a premium build quality, and while it can handle general use and engineering tasks, its integrated graphics may struggle with intensive gaming and complex 3D tasks. Consider the G15 if gaming or high-performance computing is crucial, and the Ultra 13 if you prioritize portability and build quality for everyday tasks and lighter engineering work. Give Feedback

The ASUS ROG Strix G15 is good for engineering and design, while the LG Ultra 13 is only fair.
The ASUS ROG Strix G15 is better for engineering and design due to its more powerful AMD Ryzen 9 processor and dedicated Nvidia RTX 3050 Ti graphics card. In contrast, while the LG Ultra 13 offers excellent portability and a higher resolution screen, its integrated graphics in the AMD Ryzen 7 and lesser storage make it less suited for demanding design tasks.

The ASUS ROG Strix G15 has a better screen than the LG Ultra 13 for gaming and AI, and content creation.
The ASUS ROG Strix G15 and LG Ultra 13 both boast high-resolution displays and bright panels, ensuring sharp text and vivid images for everyday tasks and detailed engineering work, but their screens don't offer the high refresh rates preferred for smooth motion in 3D applications and fast-paced gaming. For those involved in engineering and design, both laptops provide wide color gamuts, crucial for color-sensitive work, yet these displays may not deliver the ultra-vivid experience a professional might expect for color grading in video or digital artistry. General users will appreciate the clarity and brightness of both laptops for reading and multimedia consumption, but gamers and 3D designers should consider models specifically tailored to their high-refresh needs.

How the ASUS ROG Strix G15 and the LG Ultra 13 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 13.3-inch LG Gram is a fine fit if you need to travel as light as possible for as long as possible without spending a fortune to do it. It might not be particularly sturdy or have an eye-catching design and its webcam is less than ideal, but with its sharp touch display, comfortable backlit keyboard, responsive touchpad and a fingerprint reader for extra security, the Gram makes a respectible everyday laptop for business or school work."
