Very little effect up until necking - although the square cross section corners should be slightly rounded to avoid stress concentrations. After necking, final failure may vary, although I do not know if it has been studied (but I am sure there is some old paper on it).

I found this visual to be very informative and easy to understand.

Given two tensile specimens with the same gauge cross sectional area, however one area is round and the other is rectangular/square; how would the shape of the area affect the yield, tensile and elongation results from a tensile test?
