Comparison of speeds of matrix multiplication for IA32 and EM64T

Comparison of speeds of matrix multiplication for IA32 and EM64T

If you use in calculations BLAS Level 3 I advise to pass to technology EM64T since speeds EM64T and IA32 differ almost on 50 %.
It would be desirable to note, that for IA32 dgemm in Intel MKL it is realized inefficiently (see: http://www.thesa-store.com/products/ ).
