The Acer Swift X is designed for general use and is quite portable with good battery life, ideal for on-the-go tasks like presentations or writing. On the other hand, the Lenovo Legion Slim 7 is more suitable for gaming, 3D work, or machine learning applications due to its higher performance hardware, but it's bulkier and typically has shorter battery life. If you prioritize performance for intensive tasks and don't mind sacrificing portability and endurance, go for the Lenovo. However, if you want something lighter, easier to carry, and with longer battery life for everyday tasks, the Acer is the better choice. Give Feedback

The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the Acer Swift X (2021) is only fair.
The Lenovo Legion Slim 7 15.6" offers a superior gaming and 3D experience over the Acer Swift X (2021) primarily because it has a more powerful GPU, the Nvidia RTX 3060, compared to the Acer's RTX 3050, and it also boasts a higher screen refresh rate at 165 Hz versus the Acer's 60 Hz. Additionally, the Lenovo is equipped with a better CPU, the AMD Ryzen 7 5800H, which outperforms the Acer's Ryzen 5 5600U, and although both have IPS screens with similar resolutions, the higher refresh rate and stronger GPU on the Lenovo make it better suited for fast-paced gaming and detailed 3D work.

The Lenovo Legion Slim 7 has a better screen than the Acer Swift X for general use, gaming and AI, engineering and design, and software development.
For general use, both the Acer Swift X and the Lenovo Legion Slim 7 have screens that offer clear visuals and bright displays, making them suitable for everyday tasks such as browsing the internet and working with office applications. With respect to engineering and design, these laptops have screens that can represent a wide range of colors accurately, which is crucial for professionals working with visual content, although they may not cover the full spectrum needed by the most demanding designers. However, for gaming and 3D applications, the screens on these laptops fall short due to a lower refresh rate that might not keep up with fast-paced visuals, despite their sufficient resolution and panel type that provide clear and sharp images.

How the Acer Swift X (2021) and the Lenovo Legion Slim 7 15.6" compare to other laptops
"The Swift X is an Acer for entry-level gaming. With the entry-level graphics chip, our Acer not only beats every single current AMD and Intel iGPU, but also Intel's dGPU Iris Xe Max. However, despite being a GDDR6 version, the GTX does not match the expectations set by its own counterparts from our database. This may be a result of the single fan, which only produces moderate noise levels under load. The performance level of the thin and light 1.4 kg (~3.09 lbs) 14-inch laptop is impressive nonetheless."
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
