The Lenovo Flex 5 14 is more cost-effective and offers good general use with a touch screen and better portability due to its lighter weight and longer battery life, making it suitable for on-the-go usage. However, the Lenovo Legion Slim 5i, while less portable due to its weight and shorter battery life, offers a higher resolution and refresh rate display, along with a more powerful processor and dedicated graphics card, making it better suited for intensive gaming, 3D rendering, and engineering tasks. Both have ample storage and RAM, but the Legion Slim 5i provides a slight edge in performance for demanding applications. Give Feedback

The Lenovo Legion Slim 5i has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo Flex 5 has a screen that provides enough clarity and brightness for everyday tasks and standard office work which are typical in general use, but it lacks the wide color gamut needed for precision in engineering and design. The Lenovo Legion Slim 5i enhances visual experiences with its higher resolution and increased brightness, delivering vibrant and more accurate colors for engineering and design work, but for gaming and 3D applications, its lower refresh rate may not be as smooth as dedicated gaming laptops. Neither laptop has the high refresh rate screens that are ideal for gaming and 3D work where fluid motion and fast screen updates are critical for an immersive experience.

How the Lenovo Flex 5 14 and the Lenovo Legion Slim 5i 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 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."
