Processor performance states are defined by the Advanced Configuration and Power Interface (ACPI) specification, an open standard supported by all major operating systems; no additional software or drivers are required to support the technology. [1] The design concept behind Turbo Boost is commonly referred to as "dynamic overclocking". [2]
The latest badge promoting the Intel Core branding. The following is a list of Intel Core processors.This includes Intel's original Core (Solo/Duo) mobile series based on the Enhanced Pentium M microarchitecture, as well as its Core 2- (Solo/Duo/Quad/Extreme), Core i3-, Core i5-, Core i7-, Core i9-, Core M- (m3/m5/m7/m9), Core 3-, Core 5-, and Core 7- Core 9-, branded processors.
CPU-Z is more comprehensive in virtually all areas compared to the tools provided in Windows to identify various hardware components, and thus assists in identifying certain components without the need of opening the case; particularly the core revision and RAM clock rate. It also provides information on the system's GPU.
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.

With CPUs being multiplier locked, the only way to overclock is to increase the BClk, which can be raised by only 5–7% without other hardware components failing. As a work around, Intel made available K/X-series processors, which feature unlocked multipliers; with a multiplier cap of 57 for Sandy Bridge. [45]
The desktop CPUs now all have four non-SMT cores (like the i5-750), with the exception of the i5-2390T. The DMI bus runs at 5 GT/s. The DMI bus runs at 5 GT/s. The mobile Core i5-2xxxM processors are all dual-core and hyper-threaded chips like the previous Core i5-5xxM series, and share most of the features with that product line.
The 18th and most recent, M 136279841, was discovered in October 2024 using an Nvidia GPU, being the first GIMPS discovery to not have used Prime95 and its CPU computation. [ 8 ] [ 9 ] [ 10 ] 15 of the 17 primes discovered with Prime95 were the largest known prime number at the time of their respective discoveries, the exceptions being M ...
