The Lenovo Legion Slim 7 is ideal for performance-intensive tasks such as gaming, 3D rendering, and machine learning, offering a more powerful processor and graphics card, as well as greater memory and storage capacity. However, it is also pricier and less portable than the Lenovo IdeaPad Slim 3. On the other hand, the IdeaPad Slim 3 is a budget-friendly option suitable for general use like web browsing, office work, and media consumption, with respectable battery life and lighter weight making it easy to carry around. If you're focusing on value and regular tasks, the IdeaPad Slim 3 is a solid choice, but for high-end tasks and better display quality, the Legion Slim 7 is the stronger, though more expensive, contender.

The Lenovo Legion Slim 7 16" is very good for gaming and AI, while the Lenovo IdeaPad Slim 3 is poor.
The Lenovo Legion Slim 7 16" outperforms the IdeaPad Slim 3 in gaming and 3D tasks primarily because it features a more powerful Nvidia RTX 4060 graphics card and a higher screen refresh rate of 240 Hz, compared to the Slim 3's integrated AMD Vega 6 graphics and a 60 Hz refresh rate. The CPU and screen quality, such as resolution and color performance, are also superior in the Legion Slim 7, enhancing the overall experience in demanding applications.

The Lenovo Legion Slim 7 16" is very good for engineering and design, while the Lenovo IdeaPad Slim 3 is only fair.
The Lenovo IdeaPad Slim 3 has a less powerful processor and graphics, less RAM, and a lower screen resolution, making it suited for lighter engineering tasks, while the Lenovo Legion Slim 7 16" boasts a more robust processor, superior graphics, double the RAM, and a higher-resolution screen tailored for more demanding engineering and design applications. Despite the IdeaPad Slim 3 being lighter and thus more portable, the Legion Slim 7’s high-quality keyboard, lower operating noise, and better screen quality enhance the user experience for intensive tasks, justifying its increased weight and somewhat lower battery life.

The Lenovo Legion Slim 7 has a better screen than the Lenovo IdeaPad Slim 3 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the Lenovo IdeaPad Slim 3 offers a basic display that meets everyday needs with sufficient resolution and brightness, but it lacks the higher quality panel found in the Legion Slim 7, which has superior brightness and resolution for sharper and more vivid visuals. When it comes to engineering and design, the Legion Slim 7 pulls ahead with a wider color coverage that accurately represents a broader spectrum, enhancing detailed work where color precision is critical. However, for gaming and 3D applications, both laptops fall short as neither is equipped with the high refresh rate screens that are crucial for smooth motion and an immersive experience.

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."

"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."
