Performance drops in CPU core speed during testing
Performance drops in CPU core speed during testing
When the CPU is idle, it maintains its top speed (4.9GHz) thanks to turbo settings. Under stress tests like CPU-Z or Intel's AVX test, it drops to 4.5GHz, which seems unexpected since it should operate at full capacity. This behavior appears only during multi-core assessments; single-core performance remains at maximum. This variation is normal depending on the workload type.
The maximum sustained boost is 4.9 GHz for single-core or short-term multi-core performance. Intel specifications indicate it shouldn't maintain that speed continuously, as it would surpass the standard power limits of 125W or 150W. You'll notice brief spikes reaching about 4.5 GHz during full workload or stress tests.
Open BIOS and adjust the default power settings to run at 4.9GHz across all tasks. This will increase temperatures and power usage, but performance will also improve slightly.
