Models marked "thinks first" can write out their reasoning before they answer, so a job takes longer than the speed alone suggests.
Editing, gaming, CAD and other work
Each app below publishes a minimum and a recommended system requirement. We compare them with this laptop's memory and graphics memory. We do not judge the graphics chip's class, the processor generation or the operating system, because the makers describe those in words: check the source link for the exact card, processor and system they name. Many apps and games run only on Windows or only on macOS. Integrated graphics count as below any requirement for a dedicated card. Not known means the maker does not state this laptop's graphics memory.
Labels follow the makers' published lists. All use cases.
