If performance for intensive tasks like 3D modeling, machine learning or gaming is paramount, the ASUS ROG Flow X13 will serve you well, albeit with a higher price tag. However, if you seek a balance between cost and capability for general use, the Lenovo IdeaPad 3 15" could be more suitable. The ASUS model's portability and high performance may attract those who need power on the go, whereas the Lenovo offers a more affordable option with respectable performance for everyday tasks. Remember, the ASUS also typically has less battery life due to its powerful hardware, while the Lenovo may last longer but offer less in terms of graphics and processing power. Choose the ASUS if top-tier performance and portability outrank budget and battery life or the Lenovo for a wallet-friendly, long-lasting laptop primarily for general use. Give Feedback

The ASUS ROG Flow X13 has a better screen than the Lenovo IdeaPad 3 15" for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Flow X13 has a high-resolution display and vivid colors which cater well to engineering and design tasks that require accuracy, but its lower refresh rate can be a drawback for gaming where smooth visuals are key.

Sebastian Bade | February 2021
"The Asus ROG Flow X13 is not an off-the-shelf convertible. This quickly becomes clear when you take a closer look at the technical specs. The AMD Ryzen 9 5980HS is a state-of-the-art SoC with 8 cores and 16 threads, which also makes the 2-in-1 interesting as a work device. With 32 GB of RAM and a 1 TB SSD, gamers are also well taken care of. The dedicated Nvidia GeForce GTX 1650 Max-Q fits well into the overall concept and ensures a solid 3D performance. With the eGPU dock, which is equipped with a GeForce RTX 3080, the small convertible transforms into a full-fledged desktop replacement in terms of performance."

"The Lenovo IdeaPad 3 is an enduring office notebook with a powerful Ryzen APU. Lenovo's office all-rounder easily handles office and internet applications as well as modest games - the Ryzen 5 5625U APU and 16 GB of RAM make this possible. The CPU and GPU can work at consistently high clock rates. The emission values are okay, but the noise emissions should be lower under medium to full load. The relatively light notebook (approx. 1.6 kg) achieves practical battery runtimes of about 10 to 11 hours."
