Allen Ngo | May 2021
"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 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."
