The Lenovo IdeaPad Slim 3 is a budget-friendly option that is significantly less expensive and offers decent performance for general use, with enough power for casual tasks and a touchscreen feature. On the other hand, the LG Ultra 16, though pricier, comes with more advanced features and better performance, especially for engineering and work that requires more computing power. It has a larger, more vibrant display, more RAM for multitasking, and a higher battery capacity for longer use without charging. The LG Ultra also boasts a higher quality build, a quieter operating experience, and is noted for intensive gaming capabilities. If portability is a factor, both are quite portable, but the IdeaPad Slim 3 is slightly lighter. Each choice caters to different needs; the IdeaPad for cost-effective, everyday computing, and the Ultra 16 for more demanding tasks and better all-around performance. Give Feedback

The LG Ultra 16 and Lenovo IdeaPad Slim 3 are both good for general use, though the LG Ultra 16 is somewhat better.
The Lenovo IdeaPad Slim 3, with its AMD Ryzen 3 processor and 8GB of RAM, provides adequate performance for everyday tasks, but the LG Ultra 16 with a more robust Ryzen 7 processor and double the RAM at 16GB is better suited for more demanding general use applications. While both laptops have comparable storage and screen resolution, the LG's higher battery capacity and better screen aspect ratio enhance its usability over the Lenovo, which may affect your experience if portability and prolonged use without charging are important to you.

The Lenovo IdeaPad Slim 3 has a better screen than the LG Ultra 16 for engineering and design, while the LG Ultra 16 has a better screen for content creation, and software development.
For general use, the Lenovo IdeaPad Slim 3 and the LG Ultra 16 may have screens with adequate resolution and brightness, making them suitable for tasks like browsing and video streaming, but their panel type may not provide the most vivid colors or viewing angles. In engineering and design, both laptops' displays may not cover the wider color gamuts required for professional photo editing or CAD work, meaning colors might not be as accurate or consistent as needed. When it comes to gaming and 3D applications, the lower refresh rates on these laptops could lead to less smooth visuals, and the moderate importance of resolution and panel type may affect image clarity and depth perception.

Although they have very similar scores, PerfectRec considers LG Ultra 16 to be only fair for gaming and AI, while the Lenovo IdeaPad Slim 3 is poor.
The Lenovo IdeaPad Slim 3 and the LG Ultra 16 are both fair for gaming and 3D due to their decent integrated Vega graphics but may not handle intensive gaming at high settings because their GPUs are less powerful than dedicated gaming GPUs. While the IdeaPad has a standard refresh rate which can limit gameplay smoothness, the LG Ultra has a slightly larger and higher-resolution screen for better screen quality but also sticks to a standard refresh rate which is less optimal for fast-paced games. Both laptops have competent CPUs that support general gaming but aren't top-of-line for the most demanding tasks.

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."

"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."
