If you need a laptop primarily for gaming or engineering software that demands a strong graphics card, the Acer Predator Helios 300 would be a better choice due to its dedicated Nvidia RTX 3060 GPU. However, it's heavier and has a shorter battery life, making it less ideal for frequent travel. On the other hand, the Lenovo Flex 5 14 offers better portability with a lighter design and longer battery life, touch screen, and a higher resolution display, but it has integrated graphics, making it better suited for general use and not for graphic-intensive tasks. The Lenovo is also typically less expensive than 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 highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
