Patent ID: 8319782

Claim:
An information handling system, comprising: a motherboard including circuitry; a first modular component including a first parallel graphics rendering graphics hub coupled by a first data bus to at least one first graphics processing unit (GPU) that is part of the first modular component, said first modular component being coupled to the motherboard of the information handling system such that said first parallel graphics rendering graphics hub receives signals from one or more components of said motherboard, and said first parallel graphics rendering graphics hub including a cascade-out port; and a first additional modular component separate from said first modular component, said first additional modular component including a second parallel graphics rendering graphics hub coupled to at least one second GPU that is part of said first additional modular component, the second parallel graphics rendering graphics hub having a cascade-in port coupled by a second data bus to the cascade-out port of the first parallel graphics rendering graphics hub with said first additional modular component being coupled to said first modular component such that said first and second parallel graphics rendering graphics hubs are coupled together in cascade relationship with said first parallel graphics rendering graphics hub being coupled between said second parallel graphics rendering graphics hub and said motherboard and such that the second parallel graphics rendering graphics hub is only configured to exchange signals with the motherboard through the cascade-out port of the first parallel graphics rendering graphics hub and the cascade-in port of the second parallel graphics rendering graphics hub; where the second parallel graphics rendering graphics hub of the first additional modular component further comprises a cascade-out port configured for coupling to a cascade-in port of a third parallel graphics rendering graphics hub of a second additional modular component separate from said first modular component and said first additional modular component; and wherein said first parallel graphics rendering graphics hub is further configured to provide signals to said first GPU by said first data bus and to said second GPU by said second data bus and said second parallel graphics rendering graphics hub to enable parallel graphics rendering using said first GPU and said second GPU.
