What does benchmark mean in computers

Benchmark

Benchmark tests are comparative tests with which the computing power of central processing units (CPU), electronic components and devices as well as software are examined under application and boundary conditions with the help of an evaluation program. It is a benchmark for comparing the performance of different data processing systems.


In order not to limit the comparability to the comparison of purely technical performance data, the processing time of several jobs, especially in simultaneous processing, is measured and assessed using benchmarking methods. The Standard Performance Evaluation Corporation (SPEC) has developed corresponding benchmarks for the comparability of computing power and constantly adapts them to the current development of central units and computers.

In addition to the SPEC benchmarks, there are also the Whetstone test and Dhrystone test, which are carried out during an application, and the benchmarks of the Embedded Microprocessor Benchmark Consortium (EEMBC). The Whetstone benchmark measures the arithmetic computing power of coprocessors. It is about how often the coprocessor can perform small arithmetic operations within a unit of time. Dhrystone and Whetstone benchmarks are no longer frequently referenced because of their misleading measurement results and interpretations.

In addition to these, there is also the core test for determining the speed of the hard drives and the landmark test.
