This means that Turbo Boost will always engage, but only if the aforementioned limits have not been hit. More importantly, this version does not have a 'turbo time limit' (also known as Tau by Intel's definition). If the TjMax limit has been exceeded, the CPU will not clock itself back to its base clock frequency, but modulate at the lowest possible clock frequency to reduce heat as much as possible. If any of these limits are exceeded, Turbo Boost will disengage (it will not disable itself, it'll just turn inactive) and the CPU will slow itself down back to its base clock frequency.

This version of Turbo Boost does not allow a Turbo Boost-enabled CPU to exceed its rated TDP (thermal design power/point), TDC (thermal design current), and TjMax (maximum junction temperature). Note that this version of Turbo Boost was also implemented in 'Westmere-EX', 'Westmere-EP', 'Westmere-WS', 'Nehalem-EX', 'Nehalem-EP', 'Nehalem-WS', 'Gulftown', 'Beckton', 'Jasper Forest', 'Lynnfield', 'Clarksfield', 'Clarkdale', and 'Arrandale' architectures. This was historically a big problem for those who were stuck with applications that couldn't recognize or fully utilize CPUs with more than 2 cores, leaving them with unsatisfactory performance. Multi-thread Intel Turbo Boost Technology 1.0įirst introduced in the 'Bloomfield' Core i7-9xx CPUs, it was meant to reduce the single-threaded disadvantage that plagued the older 2-core+ Intel CPUs. However, the same limitations apply to the GPU as well. If there is an on-die GPU integrated into the CPU's substrate or core, the GPU will also utilize Turbo Boost to increase its speed. This technology allows Intel's CPUs to increase their speed on-demand, given that the thermal design point and temperature limits have not been exceeded. It could be also considered the direct successor of Intel's older (Dual) Dynamic Acceleration Technology, as both technologies would allow an active core to increase its speed if an inactive core was present. It is technically the spiritual successor of Foxton (Enhanced Intel SpeedStep Technology), seeing as they both had similar purposes to fulfill. On November 17th, 2008, Intel released its Core i7-920 CPU with its proprietary performance-enhancing technology called Turbo Boost. 2.1 Intel Turbo Boost Max Technology 3.0.
