    C.1.1 The UPA is a cache-coherent processor-to-memory interconnect. A key advantage of the UPA processor-to-memory interconnect is a scalable bandwidth through the support of multiple bussed interconnects for both data and address. Other advantages include more bandwidth, high-performance graphics support with two-cycle, single-word writes on the 64-bit UPA data bus, and centralized coherence and memory controller functions (see ).
