CPU Core Voltage (SVI2 TFN) is the voltage value provided by the voltage regulator to the CPU (and the value the CPU uses for internal telemetry/power management).
This value is sensed directly by the VRM and in cases where it's possible to read VRM data, it should match the VOUT value from VRM.
Vcore is the value measured somewhere along the way via a third component (i.e. SIO like ITE or Nuvoton). This value is less precise.
This topic been discussed here already and especially on the overclock.net forum, where several members did measurements and explained in detail how this works and why there are differences (vdroop, etc.).

Thank you, Martin.
