Nehalem / n ə ˈ h eɪ l əm / [1] is the codename for Intel's 45 nm microarchitecture released in November 2008. [2] It was used in the first generation of the Intel Core i5 and i7 processors, and succeeds the older Core microarchitecture used on Core 2 processors. [3]
An Intel November 2008 white paper [10] discusses "Turbo Boost" technology as a new feature incorporated into Nehalem-based processors released in the same month. [11]A similar feature called Intel Dynamic Acceleration (IDA) was first available with Core 2 Duo, which was based on the Santa Rosa platform and was released on May 10, 2007.
The Intel Core i7-975 Extreme Edition was considered the world's fastest desktop processor (until the i7-980x) by a review from Hot Hardware. It runs at a clock rate of 3.33 GHz with Turbo Boost clock rates running the processor up 3.46 GHz with all four cores put at work and 3.6 GHz with a single core at work.
Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors (Core i7, i5, i3). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors , from the former generation's 32 nm Sandy Bridge microarchitecture—also known as tick–tock model .
On February 9, 2016, Intel announced that it would no longer allow such overclocking of non-K processors, and that it had issued a CPU microcode update that removes the function. [32] [33] [34] In April 2016, ASRock started selling motherboards that allow overclocking of unsupported CPUs using an external clock generator. [35] [36]
The purpose of overclocking is to increase the operating speed of a given component. [3] Normally, on modern systems, the target of overclocking is increasing the performance of a major chip or subsystem, such as the main processor or graphics controller, but other components, such as system memory or system buses (generally on the motherboard), are commonly involved.
