Abstract: Disclosed Methods, Apparatus, and articles of manufacture to dynamically enable and/or disable prefetchers are disclosed. An example apparatus include an interface to access telemetry data, the telemetry data corresponding to a counter of a core in a central processing unit, the counter corresponding to a first phase of a workload executed at the central processing unit; a prefetcher state selector to select a prefetcher state for a subsequent phase based on the telemetry data; and the interface to instruct the core in the central processing unit to operate in the subsequent phase according to the prefetcher state.

Abstract: In one embodiment, a processor includes: at least one first core to execute instructions; at least one second core to execute instructions; and a control circuit coupled to the at least one first core and the at least one second core. The control circuit may be configured to: receive workload telemetry information regarding a workload for execution on the processor; determine a QoS distribution based at least in part on the workload telemetry information; receive a predicted workload type, the predicted workload type based at least in part on the QoS distribution; and cause at least one of the at least one first core or the at least one second core to be parked based on the predicted workload type and the QoS distribution. Other embodiments are described and claimed.
