If your priority is gaming and handling graphically-intensive tasks, the Acer Nitro 5 15 with its dedicated Nvidia RTX GPU is a superior choice. However, for daily tasks, the Lenovo Flex 5 16 is more portable, offers a higher-resolution and brighter touchscreen, and has longer battery life, making it better for productivity and on-the-go use. The tradeoff is that while the Lenovo has good overall performance, it may not handle heavy engineering applications or gaming as well as the Acer. Both laptops are similarly priced and come well-equipped for general use with ample storage and memory. Give Feedback

Sascha Mölck | June 2022
"The Acer Nitro 5 is a fast QHD gaming notebook. The Nitro 5 is a well-balanced gaming laptop for just under US$ 2400. A Core i7-12700H CPU and a GeForce RTX 3070 Ti Laptop GPU enable QHD gaming at high to maximum settings, accompanied by fast PCIe-4-SSD (1 TB) and 16 GB of RAM. Acer delivers a solid QHD gaming notebook with the Nitro 5 AN515-58. However, the laptop is not completely free of shortcomings. The CPU and GPU can work at consistently high clock rates. The laptop heats up noticeably under load, but not excessively. Noise development is on the usual class level. Once again, however, Acer needs to improve the fan control."

Andreas Osthoff | April 2023
"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."
