For better performance in 3D rendering, machine learning, and gaming, the ASUS Zenbook Pro 15 with its dedicated Nvidia RTX 3050 Ti graphics card outperforms the Lenovo Flex 5 14, which uses integrated graphics. However, the Lenovo Flex 5 14 is more portable due to its lighter weight and smaller size. The ASUS also has a higher quality OLED display, which may be better for tasks requiring color accuracy, but the Lenovo's IPS panel and higher resolution might suffice for general use and provide a sharper image. If battery life is crucial, be aware that the ASUS offers more hours of typical use, while the Lenovo has a slightly lower battery capacity. The price of the ASUS is higher, which aligns with its enhanced capabilities, whereas the Lenovo is priced lower, reflecting its position as a general-use laptop with decent performance for everyday tasks.

"The ASUS Zenbook Pro 15 offers a strong CPU, chassis, and display. One of the most popular 15.6-inch prosumer or multimedia laptops out there is the Dell XPS 15. Thus, comparisons between it and the Asus Zenbook Pro 15 are inevitable. Asus has a couple of tricks up its sleeve that XPS users are still missing out on including 1080p OLED and an AMD Ryzen CPU which help separate the Zenbook Pro 15 from the XPS 15. It also integrates a numpad and a few more port options albeit at the cost of a larger chassis size."

"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."
