Florian Glaser | August 2022
"Users who travel frequently and are looking for a portable laptop are in the right place with the Asus ZenBook 14. The sleek case is extremely light (1.2 kg) and surprisingly thin (1.5 cm). Outdoor use is also enjoyable thanks to the bright Full HD display, which is something that can rarely be said about laptops with TN or IPS panels. The excellent battery life complements this as well. Longer trips are no problem with the ZenBook 14. Another plus point is the high-performance Ryzen 7 5700U, which often leaves the Intel competition in the dust thanks to its large number of cores."

"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."
