The Gigabyte Aorus 15X offers higher graphics performance, better suited for intensive gaming, machine learning, and engineering software, but it's heavier which affects portability. Conversely, the Lenovo Slim Pro 9i, while less powerful in graphics, has a higher quality display and is significantly lighter, making it more portable, but has lower battery life. If top-tier graphic capabilities are a priority and you don't mind extra weight, the Aorus 15X is preferable. However, if you prioritize a better display, lighter design for ease of carrying and can manage with slightly less graphics performance, the Slim Pro 9i would be a better fit. Give Feedback

The Lenovo Slim Pro 9i is very good for general use, while the Gigabyte Aorus 15X is good.
The Gigabyte Aorus 15X offers powerful performance suitable for various uses due to its high-end CPU and ample RAM, alongside a quality screen; however, it is less portable and has shorter battery life compared to the Lenovo Slim Pro 9i, which is extremely portable with its lighter weight and provides a high-quality, color-accurate screen that excels in displaying sharp visuals. While both have excellent storage capacity, the Lenovo's advanced screen technology and more substantial RAM make it a compelling choice for those prioritizing media and multitasking, if they can accept a tradeoff in graphical and processing performance compared to the Gigabyte.

Tom's Hardware
Brandon Hill | February 2023
"The Gigabyte Aorus 15X is a strong showing of Raptor Lake and RTX 4000 series. While the Aorus had trouble keeping up in older games like Grand Theft Auto V, it nudged past the competition in Shadow of the Tomb Raider. It also flexed its next-generation muscle in Far Cry 6 and Borderlands 3. While we were impressed with the overall build quality and design of the Aorus 15X, the keyboard lacked good tactile feedback. The display performed well in real-world testing despite its on-paper shortcoming with brightness, but the speakers are lackluster at best."

"The Lenovo Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."
