Frequency increases occur in increments of 133 MHz for Nehalem processors and 100 MHz for Sandy Bridge, Ivy Bridge, Haswell and Skylake processors. When any electrical or thermal limits are exceeded, the operating frequency automatically decreases in decrements of 133 or 100 MHz until the processor is again operating within its design limits. Turbo Boost 2.0 was introduced in 2011 with the Sandy Bridge microarchitecture, while Intel Turbo Boost Max 3.0 was introduced in 2016 with the Broadwell-E
microarchitecture. A feature of Turbo Boost 2.0 is that it introduced time windows with different levels of power limits, so that a processor can boost to a higher frequency for a few seconds. These limits are configurable in software for unlocked processors. Some motherboard vendors intentionally use values higher than Intel's default for performance, causing the processor to exceed its
thermal design power (TDP). Some Intel Core X Processors and some newer Intel Core Processors (e.g. 10th-geneneration desktop
Core i7) support Intel Turbo Boost Max 3.0 Technology, as well as the more aggressive Intel Thermal Velocity Boost Technology, those based on ACPI CPPC. Newer version
Windows 10 and
Linux kernel support Intel Turbo Boost Max 3.0 Technology and Intel Thermal Velocity Boost Technology. == History ==
