The ASUS Zenbook Pro 16X offers superior performance for intensive 3D, machine learning, and engineering tasks with its powerful processor and dedicated graphics card, making it an excellent choice for demanding applications and creative professionals. Its OLED screen delivers stunning visuals with high resolution and color accuracy, but it comes at a higher price and more weight, which may not be ideal for frequent travelers. On the other hand, the Lenovo Flex 5 14 is more affordable and lighter, making it more portable, with sufficient capabilities for general use and casual creative work. Its battery life is longer than the ASUS, which is advantageous for on-the-go use, although its performance in demanding tasks and screen quality isn't as high-end as the ASUS. Give Feedback

The ASUS Zenbook Pro 16X has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS Zenbook Pro 16X boasts a high-resolution display with vibrant colors and brightness that make it excellent for general use and detailed engineering tasks which require accurate color representation. Its screen is less suitable for gaming due to a lower refresh rate, which is essential for smooth gameplay. On the other hand, the Lenovo Flex 5 14 offers a decent resolution for everyday tasks and is adequate for engineering work, but its color range and lower brightness levels are not on par with the Zenbook, and it also falls short in gaming performance because of its modest refresh rate.

Marc Herter, Alex Wätzel | November 2023
"The new Zenbook Pro 16X is more powerful, quieter and doesn't need to shy away from dedicated workstations and gamers. It is also comparatively compact, and our test device is the best Zenbook that we've reviewed so far. It seems equally suitable for content creators and gamers or anyone looking for a very powerful laptop that is still slim."

Allen Ngo | May 2021
"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."
