The Lenovo Legion Slim 5i offers better performance for intensive tasks like 3D rendering or machine learning with its high-end processor and dedicated graphics. It's suitable for gaming and engineering but less portable and more expensive. The LG Ultra 16 is more affordable with a solid processor for general use, offers longer battery life, and is lighter, making it highly portable. However, it has lower storage capacity and its integrated graphics limits performance for heavy tasks compared to the Lenovo. Choose the Lenovo if performance is a priority or the LG for cost savings and portability with competent general use capabilities. Give Feedback

The Lenovo Legion Slim 5i is very good for engineering and design, while the LG Ultra 16 is good.
The Lenovo Legion Slim 5i is more suited for engineering and design thanks to its powerful Intel i7 processor, superior Nvidia graphics card, and larger, higher resolution display, which is essential for detailed work, but it is heavier and less portable than the LG Ultra 16. The LG Ultra 16, on the other hand, with its AMD Ryzen processor and integrated Vega graphics, offers adequate performance for most engineering tasks and excels in portability and longer battery life, making it a practical choice for on-the-go productivity.

The Lenovo Legion Slim 5i has a better screen than the LG Ultra 16 for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, the Lenovo Legion Slim 5i offers a high-resolution and bright display with a panel that delivers sharp and vibrant visuals, making it superior to the LG Ultra 16's fair resolution and brightness which provides adequate but less impressive image quality. In engineering and design, the Legion Slim 5i's screen displays a wider range of colors, important for accuracy in these fields, whereas the LG Ultra 16 has more limited color representation. However, for gaming and 3D, the Legion Slim 5i's low refresh rate can lead to less fluid motion compared to what's often desired, despite its higher resolution and decent panel type, the refresh rate is a critical aspect for these activities where the LG Ultra also falls short.

"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."

"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."
