The Lenovo Flex 5 14 is less expensive, has a higher resolution touchscreen, and a longer battery life, making it suitable for everyday use and better for on-the-go tasks. In contrast, the Lenovo Legion Slim 7 15.6" is slightly more expensive, features a more powerful Nvidia graphics card, and a faster refresh rate display, which suits intensive gaming, 3D work, or engineering applications but comes with reduced battery life and portability. If budget and tactile interaction with your device matter most to you, the Flex 5 is a sound choice, but if performance in graphics-intense tasks is a priority and you can handle a slightly heavier device, the Legion Slim 7 would be the better option.

The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the Lenovo Flex 5 14 is only fair.
The Lenovo Legion Slim 7 15.6” outperforms the Lenovo Flex 5 14 in gaming and 3D tasks mainly because it has a superior Nvidia RTX 3060 GPU and a higher screen refresh rate of 165Hz, compared to the Flex 5’s integrated AMD Ryzen 7 7730U Vega 8 GPU and 60Hz refresh rate. Additionally, the CPU and screen quality are better in the Legion Slim 7, contributing to its stronger performance in these areas.

The Lenovo Legion Slim 7 has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, and engineering and design.
When choosing between the Lenovo Flex 5 and the Lenovo Legion Slim 7, consider that for general use, both laptops provide pleasant visuals due to their respectable resolution and brightness, but the Legion Slim 7 has an edge with a sharper and more vibrant display. For engineering and design, the Legion Slim 7 is favored because it offers a broader color spectrum, meeting higher standards in color accuracy which is critical for detailed work. However, for gaming and 3D tasks, both fall short as they lack high refresh rates, which are vital for smooth motion rendering, and the Legion doesn't offer enough advantage in this scenario to justify the cost.

How the Lenovo Flex 5 14 and the Lenovo Legion Slim 7 15.6" 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 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
