SPEC INT is a computer benchmark specification for CPU integer processing power. It is maintained by the Standard Performance Evaluation Corporation (SPEC). SPEC INT is the integer performance testing component of the SPEC test suite. The first SPEC test suite, CPU92, was announced in 1992. It was followed by CPU95, CPU2000, and CPU2006.
The actual performance will always be lower than the peak performance. [2] 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 ...
A graphical demo running as a benchmark of the OGRE engine. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it.
In computing, computer performance is the amount of useful work accomplished by a computer system.Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions.
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 ...
Before standard benchmarks were available, average speed rating of computers was based on calculations for a mix of instructions with the results given in kilo instructions per second (kIPS). The most famous was the Gibson Mix , [ 2 ] produced by Jack Clark Gibson of IBM for scientific applications in 1959.

There are many other factors to consider when comparing the performance of CPUs, like the width of the CPU's data bus, the latency of the memory, and the cache architecture. The clock rate alone is generally considered to be an inaccurate measure of performance when comparing different CPUs families. Software benchmarks are more useful. Clock ...
