The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the LG Gram 16 is only fair.
The Lenovo Legion Slim 7 offers superior gaming and 3D capabilities because it includes a dedicated Nvidia RTX 3060 graphics card and a high screen refresh rate of 165Hz, both key for smooth visuals and rendering complex scenes. In contrast, the LG Gram 16, while offering good screen quality, depends on an integrated Intel Iris Xe graphics solution and a lower refresh rate of 60Hz, which are less optimal for demanding gaming and 3D tasks.

The Lenovo Legion Slim 7 has a better screen than the LG Gram 16 for gaming and AI, while the LG Gram 16 has a better screen for content creation.
The Lenovo Legion Slim 7's screen offers crisp visuals and accurate colors due to its high resolution and color gamut coverage, great for detailed engineering work as well as everyday tasks; however, its refresh rate isn't high enough for the smooth visuals that gamers typically seek in fast-paced 3D environments. The LG Gram 16 also boasts a high-resolution display with a wide color gamut that suits general usage and professional design needs, ensuring that colors are well-reproduced and detail is sharp. Nevertheless, like the Legion Slim 7, the LG Gram 16's refresh rate is lower, so it won't deliver the fluid motion that gaming and high-end 3D graphics require.

How the Lenovo Legion Slim 7 15.6" and the LG Gram 16 compare to other laptops
"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."
"The LG Gram 16 is a lightweight device with stability issues. The LG Gram 16Z90Q with a Core i7-1260P is made with portability in mind and places less of a focus on users with high demands on performance. The compact and light chassis is particularly practical when you are on the go. The device is not only comfortably small and lightweight, it also boasts a great battery life. When connected to mains, on the other hand, the 16-inch device is rather disappointing. The standard cooling mode causes extreme volatility in terms of CPU, SSD and iGPU performance. The meager stability of the chassis may also put off some potential buyers."
