2.2 CoreMark®-Pro

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. The components of CoreMark-Pro utilizes all levels of cache with an up to 3MB data memory footprint. Many, but not all of the tests, are also using pthreads to allow utilization of multiple cores. The score scales with the number of cores but is always less than linear (dual core score is less than 2x single core).

CoreMark-Pro must not be confused with the smaller CoreMark which, like Dhrystone, is a microbenchmark contained in L1 caches of a modern processor.
