Choosing between the Lenovo Legion Slim 5i and the MSI GE66 Raider depends heavily on your priorities. If you're looking for a more affordable option with good performance for general use and some lighter engineering tasks, the Lenovo Legion Slim 5i is a smart pick. It also offers decent battery life and portability, which is great if you're often on the move. However, if you're involved in more demanding 3D work, machine learning, or gaming and are willing to invest in a higher cost, the MSI GE66 Raider brings more power and superior performance with its robust graphics card and processor. Its display also provides a sharper image, but as a tradeoff, you'll have less battery life and slightly less portability compared to the Lenovo. Give Feedback

The Lenovo Legion Slim 5i has a better screen than the MSI GE66 Raider for gaming and AI, while the MSI GE66 Raider has a better screen for general use, engineering and design, content creation, and software development.
For general use, the Lenovo Legion Slim 5i's panel type, resolution, and brightness provide clear and vibrant visuals that are easy on the eyes, making it very good for tasks like browsing and watching videos. In engineering and design, however, while its color accuracy meets the needs for precision work, it does not stand out as exceptional due to lesser coverage of professional color gamuts. Conversely, the MSI GE66 Raider excels in both general use and engineering/design applications with its superior color gamut coverage and also falls short for gaming and 3D because of its lower refresh rate, which is vital for smooth motion and rendering in fast-paced scenes.

PCMag
Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."

"The MSI Raider GE66 12UHS notebook passes with flying colors. The GE66 is a high-end notebook with strong performance. The keyboard and trackpad are still very good and score well with precise inputs as well as high build quality. Thanks to a new liquid metal cooling solution, the Intel Core i9 12900HK brings a performance increase of around 50 percent over the predecessor's Intel Core i9 10980HK. The installed graphics card in our device delivers up to 30 percent higher frame rates than the RTX 2070 Super in the MSI GE66 10SFS."
