The Lenovo Legion Slim 7 is typically more expensive but offers better performance for intensive tasks like gaming, 3D rendering, and engineering due to its powerful AMD Ryzen processor and Nvidia RTX graphics. It has a larger battery but is heavier, which slightly reduces its portability. Its screen has a higher resolution, better colour coverage, and faster refresh rate, which is excellent for both general use and specialized applications. On the other hand, the LG Ultra is much less expensive and more portable due to its lighter weight and longer battery life. Although it performs adequately for general use and has a silent, fanless operation, its integrated Vega graphics are less suited for demanding tasks. The decision between the two would rest on whether you prioritize performance for demanding applications and better display quality over cost savings and portability. Give Feedback

The Lenovo Legion Slim 7 has a better screen than the LG Ultra 16 for general use, gaming and AI, engineering and design, software development, and content creation.
If you prioritize a sharp and vibrant display for your daily tasks and professional design work, the Lenovo Legion Slim 7 with its higher resolution and bright display, as well as wide color gamuts, makes it an excellent choice despite its limitations for gaming due to a lower refresh rate. The LG Ultra, while offering a decent display for everyday productivity and some level of design work, might not be as crisp or as vivid due to its lower color coverage and brightness. However, both laptops may not be suitable for gaming or 3D applications that benefit from high refresh rates, which neither laptop prioritizes, potentially leading to less fluid visuals in fast-paced games.

Benjamin Herzig | November 2022
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."

"Unlike the gram, the Ultra PC isn't designed to be as lightweight as possible. The 16-inch laptop is a whole 400 g (0.88 lb) heavier than its 16-inch gram counterpart partly because its chassis is not made of magnesium. Other than that, the Ultra PC seems like a copy of the gram – but with longer battery life, lower noise levels, and a clean, delicate look."
