Sebastian Jentsch | March 2022
"The Swift X is an Acer for entry-level gaming. With the entry-level graphics chip, our Acer not only beats every single current AMD and Intel iGPU, but also Intel's dGPU Iris Xe Max. However, despite being a GDDR6 version, the GTX does not match the expectations set by its own counterparts from our database. This may be a result of the single fan, which only produces moderate noise levels under load. The performance level of the thin and light 1.4 kg (~3.09 lbs) 14-inch laptop is impressive nonetheless."

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."
