How the Acer Swift X (2023) and the Lenovo Legion 9i compare to other laptops
"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."
"The Lenovo Legion 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."
