As of 2018, many Intel microprocessors are able to exceed a base clock speed of 4 GHz (Intel Core i7-7700K and i3-7350K have a base clock speed of 4.20 GHz, for example). In 2011, AMD was first able to break the 4 GHz barrier for x86 microprocessors with the debut of the initial Bulldozer based AMD FX CPUs. In June 2013, AMD released the FX ...
The clock rate of the first generation of computers was measured in hertz or kilohertz (kHz), the first personal computers (PCs) to arrive throughout the 1970s and 1980s had clock rates measured in megahertz (MHz), and in the 21st century the speed of modern CPUs is commonly advertised in gigahertz (GHz).
For example, a system with an external clock of 100 MHz and a 36x clock multiplier will have an internal CPU clock of 3.6 GHz. The external address and data buses of the CPU (often collectively termed front side bus (FSB) in PC contexts) also use the external clock as a fundamental timing base; however, they could also employ a (small) multiple ...
There has been a clock speed regression for Lion Cove P-cores in Arrow Lake-S desktop processors. [17] The Core Ultra 9 285K has a peak clock speed of 5.7 GHz compared to the higher 6.2 GHz clock speed of the Raptor Lake Core i9-14900KS.

The Infinity Cache is made up of two sets of 64 MB cache that can run on its own clock rate independent from the GPU cores. The Infinity Cache has a peak internal transfer bandwidth of 1986.6 GB/s and results in less reliance being placed on the GPU's GDDR6 memory controllers. [ 8 ]
The central processing unit (CPU) consists of two x86-64 quad-core modules for a total of eight cores, [43] which are based on the Jaguar CPU architecture from AMD. [28] Each core has 32 kB L1 instruction and data caches, with one shared 2 MB L2 cache per four-core module. [44] The CPU's base clock speed is said [citation needed] to be 1.6 GHz.
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.
