The MSI Stealth GS66 is good for gaming and AI, while the Lenovo IdeaPad Slim 7i is only fair.
The MSI Stealth GS66 outperforms the Lenovo IdeaPad Slim 7i in gaming and 3D because it comes with a more powerful Nvidia RTX 3070 Ti GPU, which is more capable of handling the demands of advanced gaming graphics and 3D rendering, and also has a significantly higher screen refresh rate, leading to smoother visuals in fast-paced games. The Lenovo, while having an adequate GPU for less intensive games, uses an Intel i7-1165G7 Iris Xe integrated graphics, which isn't as powerful, and it has a standard refresh rate, which is less suited for the high frame rates desired in gaming.

The MSI Stealth GS66 has a better screen than the Lenovo IdeaPad Slim 7i for general use, gaming and AI, and engineering and design.
For general use, both the Lenovo IdeaPad Slim 7i and the MSI Stealth GS66 offer bright displays with high resolution and quality panels that provide clarity and vibrant colors, making them suitable for everyday tasks and multimedia. Engineering and design users value accurate color reproduction, and these laptops deliver with displays covering a wide range of the color spectrum, but they may not reach the top-tier color fidelity demanded by some professionals. However, for gaming and 3D applications where fast-moving visuals are common, the lower refresh rates on these laptops mean less fluid motion and slower response times, which could detract from the immersive experience and hamper gameplay.

"Among Lenovo's multiple laptop brands, the IdeaPad family is decidedly the one designed for consumers: people who want decent performance at a reasonable price. Consider, then, this laptop a paragon for the pickier members of that crowd. With a 14-inch touch-enabled display, a comfortable keyboard, an Evo-certified Intel Core i7 11th Generation CPU, and the latest Windows 11 operating system, the IdeaPad Slim 7i Pro ultraportable ($1,199 as tested) is a slick mainstream machine at a bit of a premium price, and quite capable for everyday tasks."

"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
