Right.  And to date, such routers make use of ASICs - i.e., 'hardware-based' routers, in the vernacular.  

Routers which use only centralized, general-purpose processors can't handle even a fraction of 'line-rate' without tanking, as innumerable real-world examples of said behavior over the years have repeatedly and conclusively demonstrated.
