Quick answer
Does Quick CPU distinguish performance and efficiency cores?
Hybrid Intel CPUs have different types of cores, and not every setting or sensor maps one-to-one across them.
How to check this on your PC
- Check whether your CPU is a hybrid model
- Compare logical processor numbering with documented topology
- Observe per-core clocks and load during a short workload
How to confirm the result
Look for workload placement differences without changing affinity blindly.
When comparing results, use the same power scheme, similar ambient temperature and a fixed workload. Save your starting values before experimenting so you can return to them.
A per-thread percentage is not a direct measure of work completed.

What result should I check after this procedure?
Look for workload placement differences without changing affinity blindly. Compare the observation with a saved baseline before deciding whether to keep the change.
Which hardware limitation matters here?
A per-thread percentage is not a direct measure of work completed. Save original settings so you can reverse any unexpected behavior.
