The Acer Predator Helios 300 will serve better for intensive gaming and engineering tasks due to a more powerful GPU and CPU, particularly for 3D rendering and machine learning applications. However, it's heavier and has lower battery life, making it less portable. On the other hand, the Lenovo Flex 5 16, with its high-resolution touchscreen and longer battery life, is more suited for general use and is significantly lighter, which enhances portability. The Lenovo boasts a better color display which can be important for creative work. If portability and cost are priorities, you should lean toward the Lenovo. If performance in demanding tasks takes precedence and you don't mind the extra weight and cost, go for the Acer. 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 IdeaPad Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."
