Learning objectives

What you should understand

  1. Connect frequency and idle states to latency variance
  2. Distinguish turbo benefit from thermal instability
  3. Record power policy as part of the experiment

Lab

Hands-on exercise

Measure warm-up, idle wake-up and sustained-load behavior.

Deliverable

Evidence of completion

A frequency/temperature/latency timeline with chosen operating policy.
