Editing intel/turbo boost max technology

{{intel title|Turbo Boost Max Technology 3.0 (TBMT)}}{{confuse|intel/tbt|l1=Turbo Boost Technology (TBT)}}
'''Turbo Boost Max Technology 3.0''' ('''TBMT''') is a microprocessor technology developed by [[Intel]] that provides additional single-thread performance through higher clock speed of "superior cores" based on the specific [[die]] characteristics. Despite its namesake, this feature is unrelated to Intel's {{intel|Turbo Boost Technology}}.

== History ==
Turbo Boost Max Technology 3.0 was announced around 2014 but it was only first introduced with the {{intel|Broadwell E|l=core}} processors in 2016. In 2017, Intel expanded their offering with the introduction of the {{intel|Core X}} series family.

== Mechanism ==
[[File:tbmt software.jpg|thumb|The Intel software that is used to assign affinities to various software to take advantage of TBMT.]]
No 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.

[[Intel]] attempts to exploit those "superior cores" with Turbo Boost Max Technology. During the manufacturing process, Intel is able to test each die and determine which cores possess the best overclocking capabilities. That information is then stored in the CPU in order from best to worst.

With the help of the [[BIOS]] and the Intel driver for [[Windows]] or [[Linux]], demanding workloads will be migrated to the best available core. The processor will then attempt to temporary increase the frequency to TBMT range (somewhere around 200 MHz higher than {{intel|Turbo Boost}} maximum frequency). '''demanding workloads''' is workload that exceeds the configured utilization threshold (the default value given by Intel is 90%). Certain software can be manually tagged which will automatically affinitize them to the superior cores.

'''Note:'''

* For {{intel|Broadwell|l=arch}}, TBMT applies to 1 core.
* For {{intel|Skylake|l=arch}}, TBMT applies to 2 cores.

== Compatibility ==
TBMT was originally only supported on [[Windows]]. In earlier 2016 Intel announced that they do not intend on supporting [[Linux]] at all. In August Intel started patching the Linux kernel, reversing that decision.
