Hello

Intervlan routing is usually applied on a L3 capable switch to allow communication between different vlans on your network -(inter-vlan routing) meaning the switch is able of perform routing functions just like a physical router can do

However the L3 switch can also be just a HOST switch or access layer switch, meaning if it doesn’t have to perform any routing then you can you disable ip routing.

Hi

Its too enable ip routing on a switch that is L3 capable

but L3 switches cant do things like NAT which a router can so there are limitations doing routing on L3 switch compared to an actual router , also a router would process traffic faster than an L3 switch usually

L3 switch wont generally have wan type ports either or except wan modules  , packet forwarding on routers is in software compared to ASIC on switches , switches dont support all version and styles of QOS either compared to routers

these are just some of the known differences of why you might require router over an L3 switch
