A computing system capable of parallelizing the operation of multiple graphics processing units (GPUs) supported on external graphics cards, employing a multi-mode parallel graphics rendering subsystem. The computing system includes (i) CPU memory space for storing one or more graphics-based applications, (ii) a CPU/GPU fusion-architecture chip including one or more CPUs, one or more GPUs, a memory controller for controlling the CPU memory space, and an interconnect network, and (iii) an external graphics cards supporting multiple GPUs and being connected to the CPU/GPU fusion-architecture chip by way of a data communication interface. The computing system also includes (iv) an external graphics card supporting multiple GPUs and being connected to the CPU/GPU fusion-architecture chip by way of a data communication interface, (v) the multi-mode parallel graphics rendering subsystem supporting multiple modes of parallel operation, (vi) a plurality of graphic processing pipelines (GPPLs) implemented using the GPUs, and (vii) an automatic mode control module. During the run-time of the graphics-based application, the automatic mode control module automatically controls the mode of parallel operation of the multi-mode parallel graphics rendering subsystem so that the GPUs are driven in a parallelized manner.
