The Gigabyte Aorus 15, at an upper midrange price, is better suited for intensive tasks including gaming, 3D rendering, and machine learning due to its high-performance GPU and CPU but is less portable and has a shorter battery life. The Lenovo Legion Slim 5i, priced lower, offers great value with balanced performance for engineering and general use, a slightly better battery life and portability, and a higher quality keyboard and webcam. Choose the Gigabyte if performance is paramount and cost is less of a concern; opt for the Lenovo if you prioritize portability, battery life, and savings. Give Feedback

The Gigabyte Aorus 15 has a better screen than the Lenovo Legion Slim 5i for engineering and design, while the Lenovo Legion Slim 5i has a better screen for gaming and AI.
The Gigabyte Aorus 15 offers strong resolution and brightness, making it well-suited for everyday tasks and critical for detailed engineering work, plus it covers a wide color gamut, which is essential for accurate design visuals. However, its lower refresh rate is a downside for gaming and 3D, where swift motion rendering is crucial. The Lenovo Legion Slim 5i, while providing similar benefits for general and engineering uses with good resolution, brightness, and decent color gamut coverage, also falls short for gaming and 3D due to its refresh rate limitations.

How the Gigabyte Aorus 15 and the Lenovo Legion Slim 5i compare to other laptops
"The Gigabyte Aorus 15 is a power-hungry gaming beast. The Aorus 15 is designed to run games at QHD and high to max settings. But it also cuts a good figure in other demanding applications such as video editing and rendering. This is made possible by the Core i7 12700H and GeForce RTX 3070 Ti Laptop inside the machine. A lightning-fast PCIe 4.0 SSD (1 TB) allows for short loading times."
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
