When choosing between the Acer Nitro 5 15 and the Lenovo Flex 5 14, consider the following: the Acer provides more power for 3D, machine learning, and gaming tasks and has a dedicated GPU, while the Lenovo is more portable and has a longer battery life which makes it better suited for general use and mobility. The Lenovo also has a touchscreen and a higher resolution screen, beneficial for productivity and media consumption. On the other hand, the Acer's larger size and higher refresh rate display will be an advantage for gaming and intensive tasks; however, it's heavier and has a shorter battery life, making it less ideal for on-the-go use.

"The Acer Nitro 5 is a fast QHD gaming notebook. The Nitro 5 is a well-balanced gaming laptop for just under US$ 2400. A Core i7-12700H CPU and a GeForce RTX 3070 Ti Laptop GPU enable QHD gaming at high to maximum settings, accompanied by fast PCIe-4-SSD (1 TB) and 16 GB of RAM. Acer delivers a solid QHD gaming notebook with the Nitro 5 AN515-58. However, the laptop is not completely free of shortcomings. The CPU and GPU can work at consistently high clock rates. The laptop heats up noticeably under load, but not excessively. Noise development is on the usual class level. Once again, however, Acer needs to improve the fan control."

"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."
