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.
WPrime is popular in the overclocking community for testing the performance and stability of computer processors, as Super PI is single-threaded. Its popularity stemmed from being able to utilize 100% of a multi-core processor's computing time enabling its use as a multi-threaded benchmark application in competitions, [2] computing reviews, [3] and marketing campaigns.
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.
Intel i945GC northbridge with Pentium Dual-Core microprocessor. This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series).
A related-but-opposite technique is overclocking, whereby processor performance is increased by ramping the processor's (dynamic) frequency beyond the manufacturer's design specifications. One major difference between the two is that in modern PC systems overclocking is mostly done over the Front Side Bus (mainly because the multiplier is ...
In early processors, the TSC was a cycle counter, incrementing by 1 for each clock cycle (which could cause its rate to vary on processors that could change clock speed at runtime) – in later processors, it increments at a fixed rate that doesn't necessarily match the CPU clock speed.
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), Core 3-, Core 5-, and Core 7-branded processors.
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.
