The Gigabyte Aorus 15X offers powerful performance for gaming and engineering tasks with its advanced processor and graphics card, making it suitable for intense computational tasks but at the expense of being heavier and having lower battery life. On the other hand, the Lenovo Legion Slim 7 16" is lighter and could be more comfortable for daily carry, yet still delivers high-quality performance, especially for general use. While both laptops have similar screen sizes and resolutions, the Lenovo model displays richer colors. If portability and screen quality are priorities, consider the Lenovo, but for top-tier gaming or engineering performance, the Gigabyte Aorus could be the better choice. Give Feedback

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 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."
