Graphics processing device

A graphics processing device comprising circuit chips and an external circuit, each of the circuit chips being a system on a chip (SoC), and the circuit chips being configured to cooperate and including a first SoC and a second SoC, wherein:

• the first SoC includes:
• a first graphics processing unit (GPU) configured to divide to-be-processed data into multiple input parts including a first input part and a second input part in a performance-enhancing mode, and to process the first input part to generate and output first output data in the performance-enhancing mode;
• and
• a first transceiver circuit coupled to the first GPU, and configured to transmit the second input part to the second SoC via the external circuit in the performance-enhancing mode, and further configured to receive second output data from the external circuit to forward the second output data in the performance-enhancing mode;
• the external circuit is set outside any of the first SoC and the second SoC;
• and
• the second SoC includes:
• a second transceiver circuit configured to receive the second input part from the external circuit in the performance-enhancing mode, and further configured to transmit the second output data to the first SoC via the external circuit in the performance-enhancing mode;
• and
• a second GPU coupled to the second transceiver circuit, and configured to receive and process the second input part to generate the second output data in the performance-enhancing mode, and then output the second output data to the second transceiver circuit in the performance-enhancing mode.
