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).
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 ...
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 ...
A multi-core processor (MCP) is a microprocessor on a single integrated circuit (IC) with two or more separate central processing units (CPUs), called cores to emphasize their multiplicity (for example, dual-core or quad-core). Each core reads and executes program instructions, [1] specifically ordinary CPU instructions (such as add, move data ...

When a program wants to time its own operation, it can use a function like the POSIX clock() function, which returns the CPU time used by the program. POSIX allows this clock to start at an arbitrary value, so to measure elapsed time, a program calls clock(), does some work, then calls clock() again. [1] The difference is the time needed to do ...

The Intel 8080 ("eighty-eighty") is the second 8-bit microprocessor designed and manufactured by Intel.It first appeared in April 1974 and is an extended and enhanced variant of the earlier 8008 design, although without binary compatibility. [3]
