Abstract

Described is a solid state graphics (SSG) subsystem including a die and a package, where the die includes a memory hub, graphics processing unit(s) (GPU(s)) connected to the memory hub, first memory architecture controller(s) connected to the memory hub and directly controlling access to first memory architecture(s), second memory architecture controller associated with each GPU and each second memory architecture controller connected to the memory hub and second memory architecture(s), an expansion bus first memory architecture controller connected to the memory hub and being an endpoint for a host system and an expansion bus controller coupled to the expansion bus first memory architecture controller and capable of connecting to the host system. The first memory architecture(s) and the second memory architecture(s) are either located on the SSG subsystem, located on the package, or a combination thereof.

Claims
