I've tested a set of different x86 CPUs on Linpack (n=100 and n=1000)
and found that in most cases Atlas gives more high performance.
But this may be because of using recursive LU in dgetrf of Atlas
(this algorithm is the most fast today) - but I don't know
about algorithms used in MKL 5.01 version of dgetrf.
