HWiNFO has just released a Beta version which includes a new metric called "Power Reporting Deviation".
In short, some motherboard manufacturers are misreporting the power being supplied to Ryzen CPUs. This allows the CPU to draw more power than specified, which gives it better performance on that vendor's motherboard. The downside of this is that the CPU also generates more heat.
Testing for this must be done under full load, and Cinebench R20 is suggested. Normal values for the "Power Reporting Deviation" setting should be 95%-105%, with values lower than 95% indicating that the manufacturer is overpowering the CPU.
A full writeup related to this can be found on the HWiNFO forums here:

IMPORTANT - Explaining the AMD Ryzen "Power Reporting Deviation" -metric in HWiNFO
Ryzen CPUs for AM4 platform rely on external, motherboard sourced telemetry to determine their power consumption. The voltage, current and power telemetry is provided to the processor by the motherboard VRM controller through the AMD SVI2 interface. This information is consumed by the processors...
