The Acer Nitro 5 is typically less expensive and offers a solid experience for general use and gaming with a good processor and capable graphics card. However, it has less storage compared to the Lenovo Legion Slim 5i, which might be a factor if you plan to store a lot of data or games. The Lenovo Legion Slim 5i is often a bit pricier but comes with a higher resolution screen, which can be better for engineering and design tasks that benefit from extra screen real estate and clarity. Additionally, the Lenovo has a more powerful processor and graphics, which is important for demanding 3D work and machine learning tasks, alongside a larger battery for longer unplanned work sessions. If portability is a key consideration, the Legion Slim 5i is also slightly lighter. Both laptops have a backlit keyboard and plenty of ports for peripherals, but the Lenovo offers a higher screen refresh rate, which is favorable for fast-paced gaming. Give Feedback

NotebookCheck

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."

PCMag

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
