In one embodiment, a processor includes interconnect circuitry, processing circuitry, a first cache, and cache controller circuitry. The interconnect circuitry communicates over a processor interconnect with a second processor that includes a second cache. The processing circuitry generates a memory read request for a corresponding memory address of a memory. Based on the memory read request, the cache controller circuitry detects a cache miss in the first cache, which indicates that the first cache does not contain a valid copy of data for the corresponding memory address. Based on the cache miss, the cache controller circuitry requests the data from the second cache or the memory based on a current bandwidth utilization of the processor interconnect.
