How the Gigabyte Aorus 15 and the MSI Stealth GS66 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 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."
