Not to be confused with Turbo Boost Technology (TBT).

Turbo Boost Max Technology (TBMT) 3.0 is a microprocessor technology developed by Intel that provides additional single-thread performance through higher clock speed based on the specific die characteristics. Despite its namesake, this feature is unrelated to Intel's Turbo Boost Technology.

Due to the manual configuration required, TBMT is almost always disabled by default.

History

Turbo Boost Max Technology 3.0 was announced around 2014 but it was only first introduced with the Broadwell E processors in 2016. In 2017, Intel expanded their offering with

Mechanism

Not two chips are the same; this is true even if both dies came from the very same wafer. Likewise, when stretching a processor to its limits, even the individual cores on a single monolithic integrated circuit produce slightly different performance characteristics. Testing individual cores by disabling all the other cores will reveal which ones happen to have better thermal and voltage properties and are stable at higher frequencies. They will each slightly differ. Note that this has to be done by the user on their very own chip.

Intel attempts to exploit those "better" cores with Turbo Boost Max Technology exploits.
