Our Verdict
Lenovo IdeaPad 5 15 (2021)
Lenovo IdeaPad 3 15 (2021)
The Lenovo IdeaPad 5 15 (2021) and the Lenovo IdeaPad 3 15 (2021) are very similar overall, as the IdeaPad 5 is essentially a higher-tier model of the same lineup. The IdeaPad 5 provides a better user experience as its keyboard feels more comfortable to type on, and its touchpad tracks better. Also, the IdeaPad 5's USB-C port supports charging and video output, whereas the IdeaPad 3's USB-C can only transfer data. The IdeaPad 5's Intel 11th Gen processors perform better than the IdeaPad 3's AMD Ryzen 5000-series CPUs, but they aren't as power-efficient, meaning battery life is better on the IdeaPad 3, especially for video playback.
