The Lenovo Flex 5 14 offers a lower price, longer battery life, and a touchscreen with a higher resolution than the MSI Stealth GS66. It's more suitable for general use and it's lighter, making it more portable. However, the MSI Stealth GS66 has a more powerful graphics card, faster processor, and higher screen refresh rate, which are beneficial for 3D work, machine learning, gaming, and engineering tasks. It also includes features like a backlit RGB keyboard and is built with higher quality materials but comes at a higher cost, is heavier, and has shorter battery life. Consider what's more important: portability and value, or performance and build quality. Give Feedback

The MSI Stealth GS66 is good for gaming and AI, while the Lenovo Flex 5 14 is only fair.
The Lenovo Flex 5 14's integrated graphics chip is significantly less powerful compared to the dedicated Nvidia graphics card in the MSI Stealth GS66, which directly impacts gaming and 3D performance. Additionally, the MSI has a notably higher screen refresh rate, which makes for smoother visuals in games and dynamic content, whereas the Lenovo's lower refresh rate may lead to less fluid motion.

The MSI Stealth GS66 has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, and engineering and design.
For general use, the Lenovo Flex 5 14's screen offers adequate resolution and brightness, but its panel type may not provide the wide viewing angles and color vivacity that the MSI Stealth GS66's superior panel does. When it comes to engineering and design, the MSI Stealth GS66 stands out due to its better color accuracy and wider color gamuts, which are crucial for professional color work, while the Lenovo Flex 5 14 may fall short in displaying precise colors. For gaming and 3D applications, the MSI Stealth GS66’s display lacks the high refresh rate needed for smooth visuals, and this limitation also affects the Lenovo Flex 5 14; both may not deliver the desired fluidity in fast-paced visual content.

How the Lenovo Flex 5 14 and the MSI Stealth GS66 compare to other laptops
"The highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
"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."
