CoreMark
CoreMark is a third party tool that runs a set of benchmark tests in order to measure CPU performance. CoreMark is a preferred CPU benchmarking toolset because it is compiled to be specialized for the exact physical characteristics of the CPU on the system.
What is Being Measured?
CoreMark is designed to be a very simple benchmarking tool. It produces a single-number score that allows users to make quick comparisons between different processors. CoreMark is compiled on the system for which it will run in order to establish a precise test to evaluate the performance of the CPU.
CoreMark runs the following CPU-intensive algorithms in order to produce the single-number score.
| Name | Description |
|---|---|
| List Processing | Find and sort algorithm(s) |
| Matrix Manipulation | Common matrix operations |
| State Machine | Determine if an input stream contains valid numbers |
| CRC | Cyclic redundancy check |

CoreMark-Pro
CoreMark-PRO is a comprehensive, advanced processor benchmark that works with and enhances the market-proven industry-standard EEMBC CoreMark® benchmark. While CoreMark stresses the CPU pipeline, CoreMark-Pro tests the entire processor, adding comprehensive support for multicore technology, a combination of integer and floating-point workloads, and data sets for utilizing larger memory subsystems. Together, EEMBC CoreMark and CoreMark-PRO provide a standard benchmark covering the spectrum from low-end microcontrollers to high-performance computing processors.
