The Lenovo Flex 5 16 offers higher performance for tasks like 3D and machine learning due to its more powerful processor and RAM, but it's less portable and more expensive. Its 16-inch display with higher resolution is better suited for multitasking and productivity. On the other hand, the Lenovo IdeaPad 5 15" is more budget-friendly and lightweight, making it highly portable. Though the IdeaPad's performance is slightly lower compared to the Flex 5 16, it still handles general use well. Both have touchscreens, but the Flex has a longer battery life, while the IdeaPad has a higher build quality and better keyboard. Both are not designed for intensive gaming. Give Feedback

The Lenovo Flex 5 16 has a better screen than the Lenovo IdeaPad 5 15" for general use, gaming and AI, engineering and design, and content creation.
The Lenovo Flex 5 16 has a high-resolution display that offers clear and sharp imagery, which is essential for general use and detailed engineering work, and it comes with good color accuracy that designers need. However, for gaming and 3D applications, despite its decent resolution, it falls short because it lacks a high refresh rate that would make fast-moving visuals smoother. On the other hand, the Lenovo IdeaPad 5 15" has a fair resolution and sufficient brightness for day-to-day tasks and engineering work, but it doesn't provide the wide color gamut for the most accurate color work, nor does it offer the refresh rates for optimal gaming and 3D experiences.

The Lenovo Flex 5 16 and Lenovo IdeaPad 5 15" are both only fair for gaming and AI.
The Lenovo Flex 5 16 and the Lenovo IdeaPad 5 15" are considered fair for gaming and 3D due to their integrated GPUs which, while capable, don't match the performance of dedicated gaming GPUs and only support basic screen refresh rates of 60Hz. The Flex 5 16 has a sharper display and better screen quality, but the IdeaPad 5 has a slightly better battery and is lighter, making it more portable albeit with less powerful graphics and RAM.

How the Lenovo Flex 5 16 and the Lenovo IdeaPad 5 15" compare to other laptops
"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 Lenovo IdeaPad 5 is convincing due to its long battery life. The device scores points especially with its large battery and long battery runtimes combined with its low consumption. The CPU and GPU perform in the test as one would expect, and in line with what was familiar from the somewhat smaller 14-inch sister model, the Lenovo IdeaPad 5 14."
