Its Cinebench 2024 multi-core score of 1510 trailed some Core Ultra 9 275HX/285HX laptops, though it was strong at archive decompression and Blender CPU rendering. After gaming the GPU peaked at 74 °C and fans were quiet in general use. The PCMark 10 battery test lasted about 63 minutes. Weight, size and short battery life were criticised; ports and cooling were praised.
PC Gamer: MSI Vector A18 HX reviewIn TechRadar’s three weeks with the UK model A9WIG-006UK, Indiana Jones and the Great Circle averaged 94 fps in Balanced mode and Cyberpunk 2077 at max settings (no ray tracing, DLSS Quality) about 77 fps in ECO-Silent mode. Even in Extreme Performance temperatures stayed around 77 °C, though fan noise rose noticeably. YouTube playback from full lasted about 3 hours 25 minutes and a full charge took about 2 hours. The 3.6 kg body and 400 W adapter were called hard to carry, the speakers weak and the adapter cable short.
