Selecting between the Acer Aspire 5 17 and the Lenovo Slim Pro 9i involves considering your priorities. If a larger screen and a lower cost are important, the Acer might be the better choice, although it has less power and shorter battery life. On the other hand, the Lenovo offers a smaller yet higher-quality display, a substantial boost in performance suitable for 3D, machine learning, and engineering tasks, and longer battery life, but it comes at a higher price. The Lenovo is also more portable, with a lighter weight, and features a higher-quality keyboard, webcam, and speakers, along with cutting-edge gaming capabilities like hardware ray tracing and DLSS. If your work demands intensive computing or you need the best portability and screen quality, the Lenovo would be recommended, despite the added expense. Give Feedback

However, for 3D tasks and gaming, where smooth motion is key, both laptops may fall short due to lower refresh rates, even though the Lenovo's higher resolution and panel quality partially compensate in terms of clarity and image quality.

Marcus Schwarten | March 2021
"The Acer Aspire 5 17 laptop shows the expected strengths in the test. Besides the usual high build quality, the configuration convinces in most benchmarks and tests. The combination of CPU, GPU, and RAM is absolutely sufficient for the everyday office and browsing tasks of a laptop. It also renders the odd game passably if the requirements aren't too high. We liked the matte display in the test as well as the fairly manageable dimensions despite the screen size. It can also be used outdoors, even if it's certainly not a laptop designed for mobility."

"The Lenovo Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."
