The Acer Nitro 5 17, with its powerful Nvidia RTX 3080 graphics card, is more suited for intensive gaming and engineering applications that require high performance. It also has a larger screen, which might be preferable if screen size is a priority. However, it is heavier and thus less portable than the Lenovo Flex 5 14, which has a smaller screen but offers higher portability, touch capabilities, and longer battery life, making it a better choice for general use, taking notes, drawing, or frequent travel.

The Acer Nitro 5 17 has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, engineering and design, and content creation.
For general use, the Acer Nitro 5 17's superior resolution and brightness make the display more vivid and clear compared to the Lenovo Flex 5 14, providing a more comfortable viewing experience for everyday tasks. When it comes to engineering and design, the Acer's coverage of color gamuts such as DCI-P3 and Adobe RGB is higher, offering more accurate color reproduction necessary for professional creative work. However, for gaming and 3D applications, the lower refresh rate of the Acer's panel makes it less suitable as it can’t display as many frames per second as a gaming-optimized screen, leading to less fluid motion during fast-paced scenes.

Sascha Mölck | August 2021
"The Acer Nitro 5 17 is a solid mid-range gamer. The Nitro 5 does not belong to the top group of RTX 3070 notebooks: Compared with the RTX 3070 notebooks tested so far, the computer delivers below-average frame rates - this is due to the 100-watt TGP. The GPU performance can be increased a bit with a firmware update. The device scores with a high level of CPU performance. Throttling is not a concern. CPU and GPU can produce their performance constantly. The laptop heats up moderately under load. The noise development is on the usual class level."

"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."
