The Acer Swift X offers excellent value for general use and light gaming with its Ryzen 5 5600U processor and RTX 3050 graphics card, providing good performance without breaking the bank. It's also quite portable, with a slim design and decent battery life. However, its screen isn't as vibrant as some competitors, and it lacks the touchscreen functionality that some users might miss. On the other hand, the Lenovo Yoga Pro 9i is a premium choice with a high-resolution Mini LED touchscreen that delivers exceptional color accuracy and brightness, making it ideal for creative professionals and those who demand the best display quality. Its Core Ultra 7 155H processor and RTX 4050 graphics offer superior performance for more demanding tasks like 3D rendering and machine learning. It's also well-equipped for productivity with a backlit keyboard, number pad, and robust build quality. However, this performance and quality come at a higher price point, and it's slightly heavier, which might affect its portability for some users. In summary, if you prioritize a high-quality display, top-tier performance, and a premium build, and are willing to pay more and carry a bit more weight, the Lenovo Yoga Pro 9i is the way to go. But if you're looking for a cost-effective, portable laptop for everyday tasks and some light gaming, the Acer Swift X is a strong contender. Give Feedback

Sebastian Jentsch | March 2022
"The Swift X is an Acer for entry-level gaming. With the entry-level graphics chip, our Acer not only beats every single current AMD and Intel iGPU, but also Intel's dGPU Iris Xe Max. However, despite being a GDDR6 version, the GTX does not match the expectations set by its own counterparts from our database. This may be a result of the single fan, which only produces moderate noise levels under load. The performance level of the thin and light 1.4 kg (~3.09 lbs) 14-inch laptop is impressive nonetheless."
