Choosing between the Acer Predator Helios 300 and the Lenovo Legion Slim 7 16" depends on what's most important to you. If you value a higher resolution and lighter weight for better portability, along with superior performance in 3D rendering and machine learning, the Legion Slim 7 would be the better option. It also has a longer battery life which is convenient if you're often on the go. However, the Helios 300, while heavier, may come at a slightly lower price and still delivers solid gaming and engineering performance. If budget is a concern and you don't mind the extra weight, the Helios 300 could accommodate your needs well. Both have similar RAM and storage configurations, but note that the Helios 300 comes with a lower resolution display and less impressive battery life. Give Feedback

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 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."
