The Lenovo IdeaPad Slim 5i offers a larger screen and a slightly better processor for general use, but with less portability due to its larger size and weight compared to the LG Ultra 13. The LG Ultra 13 has a smaller screen but is notably lighter and provides longer battery life, featuring an AMD processor that's competent for similar tasks. If portability and battery life are top priorities and you're okay with a smaller screen, the LG Ultra 13 is an excellent choice. On the other hand, if you prefer a larger display and can handle a bit extra weight, the Lenovo IdeaPad Slim 5i would suit you better. Both laptops are similarly priced, so the decision hinges on your preferences for screen size, weight, and battery life. Give Feedback

The LG Ultra 13 has a better screen than the Lenovo IdeaPad Slim 5i for general use, and engineering and design.
For general use, the Lenovo IdeaPad Slim 5i offers sufficient resolution and brightness, but the LG Ultra 13 might provide a sharper image and better visibility in various lighting conditions due to higher brightness and resolution. When considering engineering and design tasks, the LG Ultra 13's display covers a wider range of colors, allowing for more precise and vibrant visual work, while the Slim 5i may fall short in this aspect. For gaming and 3D applications, both laptops' displays lack the higher refresh rates demanded by these tasks for smooth visuals, despite their varying resolutions and panel types.

The Lenovo IdeaPad Slim 5i and LG Ultra 13 are both only fair for gaming and AI.
The Lenovo IdeaPad Slim 5i and the LG Ultra 13 are considered fair for gaming and 3D because both have integrated graphics with modest performance capabilities and screens with standard refresh rates. The IdeaPad Slim 5i employs Intel's Iris Xe graphics and a screen with moderate quality, while the LG Ultra opts for AMD's Vega 7 graphics and offers better color coverage, but neither is optimized for the high refresh rates (60Hz) or the powerful GPUs that demanding games and 3D applications often require.

Although they have very similar scores, PerfectRec considers Lenovo IdeaPad Slim 5i to be good for engineering and design, while the LG Ultra 13 is only fair.
The Lenovo IdeaPad Slim 5i is better suited for engineering and design due to its more powerful Intel i5 processor with Iris Xe graphics and a higher resolution 16:10 screen, providing both computational strength and screen space for complex tasks. In contrast, the LG Ultra 13, while more portable and with excellent build quality, has a weaker AMD Ryzen 7 processor with Vega 7 graphics and a standard 16:9 screen resolution, which may not be as effective for demanding engineering software and detailed design work.

"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."

"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."
