Microsoft’s August Windows 11 update expands its Low Latency Profile beyond system-interface elements to application startup. Instead of allowing CPU frequency to rise gradually as load increases, Windows requests a rapid burst near the processor’s maximum frequency, completes the work sooner and then returns the CPU to a deeper idle state. The E-cores reportedly reached approximately 80% of their maximum frequency during the startup interval. The profile can potentially improve responsiveness without increasing average energy consumption, because the processor spends less time in an intermediate active state.
