Benchmark Intel

The purpose of this page is to show the comparison of the best performing BLAS/LAPACK implementations and Eigen2 on an Intel(R) Pentium(R) D CPU. By best performing I mean Intel MKL, GotoBLAS, ATLAS, and ACML (by AMD). Other implementations of BLAS/LAPACK are notably slower (see benchmark) and therefore not worth testing (and using). ACML was not included in the original benchmark.
