For a fee, SPEC distributes source code files to users wanting to test their systems. These files are written in a standard programming language, which is then compiled for each particular CPU architecture and operating system. Thus, the performance measured is that of the CPU, RAM, and compiler, and does not test I/O, networking, or graphics.

The performance of a computer is a complex issue that depends on many interconnected variables. The performance measured by the LINPACK benchmark consists of the number of 64-bit floating-point operations, generally additions and multiplications, a computer can perform per second, also known as FLOPS. However, a computer's performance when ...
SPEC was founded in 1988 and its membership comprises over 120 computer hardware and software vendors, educational institutions, research organizations, and government agencies internationally. SPEC benchmarks and tools are widely used to evaluate the performance of computer systems; the test results are published on the SPEC website.
The Whetstone benchmark is a synthetic benchmark for evaluating the performance of computers. [1] It was first written in ALGOL 60 in 1972 at the Technical Support Unit of the Department of Trade and Industry (later part of the Central Computer and Telecommunications Agency) in the United Kingdom.
Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.

CoreMark is a benchmark that measures the performance of central processing units (CPU) used in embedded systems.It was developed in 2009 [1] by Shay Gal-On at EEMBC and is intended to become an industry standard, replacing the Dhrystone benchmark. [2]
