‘Uncore’ roughly equates to logic outside the CPU cores but residing on the same die. Traffic (for example, Data Reads) generated by threads executing on CPU cores or IO devices may be operated on by logic in the Uncore. Logic responsible for managing coherency, managing access to the DIMMs, managing power distribution and sleep states, and so forth.
