Modular GPU architecture for clients and servers

A graphics processing apparatus including:

• a circuit board including a host interconnect;
• and
• a system on a chip integrated circuit (SoC) including an active base die including a fabric interconnect and a first chiplet including a switched fabric, wherein the first chiplet is configured to couple with the active base die via an array of interconnect structures, the array of interconnect structures additionally to couple the fabric interconnect with the switched fabric, the first chiplet including:
• a first modular interconnect configured to couple a block of graphics processing resources to the switched fabric, wherein the first modular interconnect is configured to selectively couple, to the switched fabric, one of a first block of graphics processing resources having a first number of graphics core clusters and a second block of graphics resources having a second number of graphics core clusters;
• a second modular interconnect configured to couple a memory interconnect of a memory subsystem with the switched fabric and the block of graphics processing resources, the memory interconnect including a set of memory controllers and a set of physical interfaces;
• and
• a tile-to-socket interface to couple a connectivity die to the first chiplet, the connectivity die to enable a multi-board graphics processor via a multi-board connection with an external general-purpose graphics processor, the multi-board connection established via the first chiplet.
