The ASUS ROG Zephyrus G15 is very good for engineering and design, while the Acer Swift X (2021) is good.
The ASUS ROG Zephyrus G15 is very good for engineering and design use due to its higher performance processor, double the RAM, and a significantly better GPU compared to the Acer Swift X, all of which contribute to more efficient processing of demanding tasks and better handling of complex graphics. Additionally, the ASUS has a superior screen with better resolution and quality, including color space coverage which is crucial for design accuracy, but it's heavier and might be less portable, with a slightly shorter battery life compared to the Acer Swift X which trades some performance for better portability and slightly longer unplugged use.

The ASUS ROG Zephyrus G15 has a better screen than the Acer Swift X for general use, gaming and AI, engineering and design, and software development.
For general use, where clarity, sharpness, and the ability to use the laptop in various lighting conditions are key, both the Acer Swift X and ASUS ROG Zephyrus G15 offer high-resolution displays with bright panels, ensuring text and images are crisp and easy to read. In engineering and design, accurate colors are crucial, and the ASUS ROG Zephyrus G15's display covers a wider color gamut, providing a broader range of colors which is essential for professional color work. However, for gaming and 3D applications that benefit from smoother motion and quicker feedback, the Acer Swift X falls short as it lacks a high refresh rate display that the ASUS ROG Zephyrus G15 also does not provide, making neither ideal for the most immersive visual experience in fast-paced games or 3D simulations.

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."

"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."
