There is provided a multichip ray tracing device. The multichip ray tracing device includes a plurality of memory units; an acceleration structure division processing unit that divides an acceleration structure (AS) into a plurality of divided acceleration structures and stores each of the plurality of divided acceleration structures in a corresponding memory unit among the plurality of memory units; and a plurality of ray tracing core units connected to the plurality of memory units. Each of the plurality of ray tracing core units performs an internal ray tracing (Internal RT) operation for a corresponding divided acceleration structure and transmits corresponding ray information to a corresponding ray tracing core unit to perform an external ray tracing (External RT) operation when attempting to access a data node that is not in the corresponding divided acceleration structure in the process of the internal ray tracing operation.
