The MSI Stealth GS66 is good for gaming and AI, while the Lenovo ThinkBook 13x is only fair.
The MSI Stealth GS66's higher screen refresh rate and more powerful GPU make it more suitable for smooth, responsive gaming and 3D applications than the Lenovo ThinkBook 13x, which may not perform as well in these areas due to its less capable GPU and lower refresh rate. Although the CPU and screen quality are also important and the ThinkBook 13x may compete well in these aspects, they don’t outweigh the significant advantages that the MSI's superior GPU and screen refresh rate provide for gaming and 3D tasks.

Florian Glaser | February 2022
"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."
