Yes, same idea, this on another computer, Debian packaged ATLAS:

Sympy high-precision pinv SSE
72.0232781366615313
Local numpy 1.10.4 linalg pinv
72.0232781366614176
Local scipy 0.16.0 linalg pinv
72.0232781366600392
Local scipy 0.17.0 linalg pinv
72.0232781368149233

Difference at 10th dp, but still two orders of magnitude different
from the other variations.
