Sorry for going a bit off-topic, but: do you have any links to the benchmarks? I googled around, but I haven't found anything. FWIW, on my own machines OpenBLAS is on par with MKL (on an i5 laptop and an older Xeon server) and actually slightly faster than ACML (on an FX8150) for my use cases (I mainly tested DGEMM/SGEMM, and a few LAPACK calls). So your claim is very surprising for me. Also, I'd be highly surprised if OpenBLAS would be slower than Eigen, given than the developers themselves say that Eigen is "nearly as fast as GotoBLAS"[1], and that OpenBLAS was originally forked from GotoBLAS.
