The Acer Nitro 5 15 is less expensive, which makes it an attractive option if you're on a budget. It has a solid mid-range processor and graphics card suitable for general use and moderate gaming or engineering tasks. However, the Lenovo Legion 9i, while more expensive, offers significant improvements in performance, with a top-end processor and graphics card that can handle intensive 3D, machine learning, and gaming applications much more efficiently. It also has a higher resolution display with better color accuracy, which can be a big plus for creative work. As for battery life and portability, the Acer offers longer usage on a single charge and is slightly lighter, making it more convenient if you need to take your laptop on the go frequently. The Lenovo, in contrast, has a higher quality build but is heavier, which might be less ideal for frequent travel. Depending on your priorities—whether cost, performance, or portability—either of these laptops could fit the bill, but each excels in different aspects. Give Feedback

The Lenovo Legion 9i has a better screen than the Acer Nitro 5 15 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the Lenovo Legion 9i stands out with its high-resolution, bright display, offering crisp and vibrant visuals, while the Acer Nitro 5's display, although adequate, lacks the same level of clarity and illumination. Engineering and design professionals would prefer the Legion 9i for its superior color accuracy and wider color gamut coverage, ensuring that designs are viewed with the truest colors possible, a feature where the Nitro 5 falls short. However, for gaming and 3D applications, both laptops might disappoint due to lower refresh rates, which are crucial for smooth motion rendering, though they may still deliver acceptable performance for casual gaming or less demanding 3D tasks.

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."

"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."
