The Lenovo Flex 5 is often slightly less expensive and offers a larger 16-inch screen, longer battery life, and is equipped with an i7 processor which is great for multitasking. However, it's heavier and has a lower portability score. The Lenovo IdeaPad Slim 7i Pro is more portable owing to its lighter weight and smaller 14-inch screen, it has a slightly better display quality with a higher resolution and refresh rate, and it is equipped with an i5 processor well-suited for everyday tasks. The 7i Pro also has a higher build quality score and slightly better keyboard quality, but it has a shorter battery life. If portability and screen quality are your top priorities, the IdeaPad Slim 7i Pro is the better option, while the Flex 5 is more suitable for those who prioritize screen size and battery life. Both laptops have similar storage, RAM, and integrated graphics, making them capable of handling general use, but not ideal for intensive gaming or heavy engineering software. Give Feedback

The Lenovo IdeaPad Slim 7i Pro has a better screen than the Lenovo Flex 5 16 for general use, gaming and AI, and engineering and design.
For general use, where clarity, sharpness, and comfortable viewing are key, both the Lenovo Flex 5 16 and IdeaPad Slim 7i Pro provide satisfactory experiences with their resolutions and bright panels, but the Slim 7i Pro offers superior screen quality with better visibility and detail. In engineering and design tasks, accurate color representation is essential; the Slim 7i Pro stands out with a wider color gamut, making it a stronger choice for professionals needing precise color matching. However, for gaming and 3D applications that benefit from smoother motion and quick screen response, both laptops are limited by lower refresh rates, which could hamper the experience compared to models specifically designed for such demanding graphics requirements.

The Lenovo Flex 5 16 and Lenovo IdeaPad Slim 7i Pro are both good for general use.
The Lenovo Flex 5 16 is well-suited for general use due to its solid performance from the Intel i7 processor and integrated graphics, ample RAM, and a high-quality touchscreen with a decent battery life, although it is heavier and thicker, which affects portability. Conversely, the Lenovo IdeaPad Slim 7i Pro, with a slightly lower-tier Intel i5 processor, also offers sufficient power for day-to-day tasks, high screen resolution, and better portability because of its lighter and thinner design, making it a favorable choice for users who prioritize ease of carrying and longer battery life.

The Lenovo Flex 5 16 and Lenovo IdeaPad Slim 7i Pro are both only fair for gaming and AI.
The Lenovo Flex 5 16 offers a fair gaming experience with an integrated GPU suitable for light gaming and a standard screen refresh rate of 60Hz, which limits its ability to display fast-moving visuals smoothly. In contrast, the Lenovo IdeaPad Slim 7i Pro also features an integrated GPU but has a higher screen refresh rate of 90Hz, which is better for gaming and 3D applications but still may struggle with more demanding tasks compared to laptops with dedicated GPUs.

The Lenovo Flex 5 16 and Lenovo IdeaPad Slim 7i Pro are both good for engineering and design.
The Lenovo Flex 5 16 is well-suited for engineering and design due to its powerful processor, high amount of RAM, capable GPU, and high-quality screen; the Lenovo IdeaPad Slim 7i Pro is also optimal for these tasks for similar reasons, with a comparably high performance CPU, ample RAM, a robust GPU, and a screen with high resolution and color accuracy. Both laptops offer the essential features for demanding engineering software and detailed design work, while tradeoffs include the Flex 5 16 being less portable and the Slim 7i Pro having a potentially less comfortable keyboard and louder operating noise.

Andreas Osthoff | April 2023
"The Lenovo IdeaPad Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."

"The main selling point of the IdeaPad Slim 7i Pro versus a regular IdeaPad Slim 7 is its faster Core H-series CPU. In reality, the Core i7-11370H is only marginally faster than the U-series Core i7-1165G7 to the point where most users are not likely to notice the benefits. The slight performance uptick comes at the cost of slightly higher power consumption as well meaning owners will have to deal with potentially warmer temperatures or louder fans to compensate. Unless if you happen to be a power user, then the regular non-Pro model will be more than enough. Once you go 90 Hz, you can't go back."
