One embodiment of the invention sets forth a technique for efficiently combining two graphics processing units (“GPUs”) to enable an improved price-performance tradeoff and better scalability relative to prior art multi-GPU designs. Each GPU's memory interface is split into a first part coupling the GPU to its respective frame buffer and a second part coupling the GPU directly to the other GPU, creating an inter-GPU private bus. The private bus enables higher bandwidth communications between the GPUs compared to conventional communications through a PCI Express™ bus.
Performance and scalability are further improved through render target interleaving; render-to-texture data duplication; data compression; using variable-length packets in GPU-to-GPU transmissions; using the non-data pins of the frame buffer interfaces to transmit data signals; duplicating vertex data, geometry data and push buffer commands across both GPUs; and performing all geometry processing on each GPU.
