The Acer Predator Helios 300 leans more towards gamers with its gaming laptop appearance, RGB keyboard backlighting, and higher capability for fast motion and gaming. It's a bit heavier and has lower battery life, making it less portable. On the other hand, the Lenovo Slim Pro 9i offers more storage, more RAM, and is significantly lighter and thinner, which enhances its portability. It features a high-resolution mini LED display with touchscreen, making it more suitable for high-quality media consumption and professional tasks. If you want powerful performance for intensive tasks like 3D or machine learning and don't mind investing a bit more, the Lenovo could be a better pick; however, if budget and gaming are your focus, the Acer may be more appealing.

Christian Hintze | November 2022
"The Acer Predator Helios 300 review is an overclocked gaming laptop with a good display. The Predator is large, heavy, and loud, but also offers plenty of performance according to gamers. An overclocked gaming laptop - or its user - also has to struggle with the usual disadvantages we mentioned above. On the other hand, overclocking is optional, and those who like it quieter and can live with a few less frames per second can also switch to the significantly more moderate Standard mode. Then the Helios 300 won't be any louder than the competitors."

"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."
