The Lenovo IdeaPad Slim 3 is more budget-friendly and offers more storage out of the box, but it has less memory and a less powerful CPU compared to the LG Ultra 13. With a larger screen, the Lenovo could be more suitable for users who prefer a bigger display for their tasks, yet this makes it less portable than the LG. The LG, while more expensive, has a better CPU and more memory, which may make it better for intensive tasks and multitasking. It's also lighter with a higher portability score, thus more convenient for travel. The Lenovo has a dedicated number pad, beneficial for those who frequently input numbers, but the LG's keyboard has a better quality score. Both have similar battery life for typical usage, so your choice may lean towards the LG for performance or the Lenovo for cost-saving and a larger screen. Give Feedback

The LG Ultra 13 and Lenovo IdeaPad Slim 3 are both only fair for engineering and design, though the LG Ultra 13 is somewhat better.
The Lenovo IdeaPad Slim 3, with its AMD Ryzen 3 processor and 8GB of RAM, may face limitations in heavy engineering software, while its larger screen can benefit design work but compromises portability. Conversely, the LG Ultra 13's more powerful AMD Ryzen 7 processor and double the RAM are better suited for complex tasks, although its smaller storage and screen may restrict extensive design projects and multitasking.

The LG Ultra 13 has a better screen than the Lenovo IdeaPad Slim 3 for general use, and engineering and design.
The Lenovo IdeaPad Slim 3 offers sufficient resolution and brightness for everyday tasks but lacks a high-quality panel and wide color gamut, making it less vibrant for detailed engineering work and subpar for the fast-moving visuals in gaming. The LG Ultra 13 provides better screen quality overall with higher resolution and brightness, as well as more accurate colors, benefiting engineers and designers in need of precise color representation, but falls short for gaming due to its standard refresh rate. Neither model is ideal for 3D work or gaming where high refresh rates are crucial for smooth visuals, though the LG's superior display may offer a slightly better experience in less demanding scenarios.

Although they have very similar scores, PerfectRec considers LG Ultra 13 to be only fair for gaming and AI, while the Lenovo IdeaPad Slim 3 is poor.
The Lenovo IdeaPad Slim 3 is equipped with a Vega 6 GPU and a screen that refreshes 60 times per second, which is just adequate for casual gaming and 3D applications, but the larger 15.6-inch screen may offer a more immersive experience despite its modest performance hardware.

Olivier Martin, Ryan Lim, and John Peroramas | May 2023
"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."

Joshua Goldman | April 2017
"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."
