The Gigabyte Aorus 15 is typically more expensive and offers a more powerful GPU and CPU, which makes it better suited for intensive gaming and engineering tasks. It also has a higher resolution display but shorter battery life compared to the Lenovo Legion Slim 7, which is lighter, making it more portable, and it offers longer battery life. If top-tier performance is a priority and you're less concerned about weight and battery life, the Gigabyte Aorus 15 is a good choice. However, if you prioritize a balance between performance, weight, and longer battery life for general use or on-the-go gaming, the Lenovo Legion Slim 7 would be a better fit. Give Feedback

The Gigabyte Aorus 15 is very good for gaming and AI, while the Lenovo Legion Slim 7 15.6" is good.
The Gigabyte Aorus 15 is equipped with a Nvidia RTX 3070 Ti GPU and a high-resolution screen offering great refresh rates, which are crucial for smooth and visually intense gaming and 3D applications, while the Lenovo Legion Slim 7 features a slightly less powerful Nvidia RTX 3060 GPU with a lower resolution screen but matches the refresh rate, providing a solid gaming experience but with less graphic detail. Both have powerful CPUs and high-quality, high-refresh-rate IPS displays which contribute to an immersive gaming experience, but the superior GPU in the Aorus 15 gives it an edge for the very highest gaming demands.

The Gigabyte Aorus 15 has a better screen than the Lenovo Legion Slim 7 for general use, engineering and design, and content creation.
The Gigabyte Aorus 15 boasts excellent resolution, panel quality, and brightness, making it ideal for everyday tasks and ensuring clarity and detail for intricate engineering and design work with its wide-ranging color gamut. However, its lower refresh rate diminishes the smoothness and responsiveness crucial for an immersive gaming and 3D experience.
The Lenovo Legion Slim 7 provides a good balance of screen quality with respectable brightness, resolution, and panel type suitable for general use and engineering tasks which require accurate color representation, but its less-than-optimal refresh rate limits its capability to deliver the fluid visuals that gaming and 3D applications demand.

How the Gigabyte Aorus 15 and the Lenovo Legion Slim 7 15.6" 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 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
