What is difference between Ifort and Gfortran?

gfortran auto-vectorization isn’t implied until -O3, while ifort -O2 implies it. auto-vectorization of sum reductions generally improves accuracy, more so with ifort than with gfortran, as ifort uses more partial sums. The options quoted above turn off vector sum reduction for both compilers.
