Windows Task Manager Performance tab CPU utilization

Affected Platforms:

  • Latitude 5340
  • Latitude 5540
  • Latitude 7340
  • Latitude 7440
  • Latitude 7640
  • Precision 3580
  • Precision 3581

Cause

The Intel generation 13 processor Raptor Lake (RPL-U15) has a 15W thermal design power (TDP). Intel has confirmed that the utilization reaches 100% only when the CPU power is higher than the TDP power. Once the TDP is not higher than the level recommended by Intel, the utilization is lower than 100%. The only way to determine when the CPU power is higher than the TDP power is by using third-party utilities.

Resolution

This is expected behavior. This is working as designed as confirmed by Intel.
