The Acer Nitro 5 17 is a more budget-friendly option with a midrange price and generally costs significantly less than the Lenovo Legion 9i, which has a high-end price. For more demanding applications like engineering and 3D modeling, the Lenovo Legion 9i may perform better with its superior processor and graphics card. The Lenovo also has a substantially larger battery capacity and higher screen resolution but offers less battery life than the Acer Nitro when it comes to typical usage. Although both have the same amount of storage, the Lenovo offers twice the RAM of the Acer. Portability is fairly similar, with the Lenovo being slightly lighter. If you prioritize performance and display quality and don't mind a higher cost, the Lenovo Legion 9i could be a better choice, whereas the Acer Nitro 5 17 offers a balance between price and performance for less-intensive gaming and general use.

The Lenovo Legion 9i has a better screen than the Acer Nitro 5 17 for general use, gaming and AI, engineering and design, content creation, and software development.
The Acer Nitro 5 17, with solid resolution and brightness, offers a comfortable viewing experience for everyday tasks and fine detail work required in engineering, but its lower refresh rate isn't ideal for smooth rendering in gaming and 3D applications.

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."

Matthew Buzzi | December 2023
"The Lenovo Legion 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."
