If you prioritize a lighter and thinner laptop with longer battery life for portability and travel convenience, the Lenovo Legion Slim 7 is a compelling choice with a still respectable performance for general use and gaming. On the other hand, the Lenovo Legion 7, while heavier and with a shorter battery life, offers a larger and more vivid screen with superior color coverage, stronger performance for 3D tasks, machine learning applications, and engineering software, making it suitable for more demanding computing activities. Keep in mind, the Legion 7 tends to be slightly more expensive than its Slim counterpart. Give Feedback

The Lenovo Legion 7 has a better screen than the Lenovo Legion Slim 7 for general use, gaming and AI, engineering and design, and content creation.
The Lenovo Legion 7 boasts a high-resolution display with bright and vivid colors, which enhances the viewing experience for general tasks and detailed engineering work, but for gaming and 3D, its lower refresh rate may not deliver the smooth visuals that fast-paced action requires. The Lenovo Legion Slim 7 offers a similarly impressive display that works well for everyday use and is adequate for design applications with accurate color representation, although like its counterpart, it lacks the higher refresh rate desired for gaming and immersive 3D environments. Screen quality in both models is tailored more towards professional and general use rather than the high-speed demands of gaming and 3D graphics.

"The Lenovo Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."

"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."
