The Gigabyte Aorus 15P offers more storage and double the RAM compared to the MSI Stealth GS66, which can be preferable for heavy multitasking and data-intensive tasks. However, the MSI has a newer processor, which may provide better performance for the latest software and games. Both laptops have similar battery capacities and high refresh rate displays but the MSI's display refreshes at a higher rate, which can be more appealing to gamers. While the Gigabyte is cheaper and might be more cost-effective, the MSI Stealth is slimmer and slightly lighter, enhancing portability. Consider the Aorus 15P if maximum performance for the price is critical, and the Stealth GS66 for a balance between performance and portability. Give Feedback

"The Aorus 15P is a high-end gaming laptop with fast 360 Hz display. Gaming performance in the Aorus 15P YD is very high thanks to the Nvidia GeForce RTX 3080 installed here. However, with the use of the Intel Core i7-11800H, CPU performance also closes in on the strong competition from AMD. SSD performance is excellent as well, and it leaves no room for criticism. Thanks to the built-in Intel Core i7-11800H, the system performance of the Aorus 15P YD increases significantly."

"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
