I wish that they'd throw us integer guys a bone too. Adding
the instructions for floating point is nice, but it would be
nice to have those for integer instructions too for those of
us that don't need the accuracy of floating point.

They can each do 4 FOPS per clock, but 2 adds + 2 multiplies is hardly any better than 2 adds + 1 multiply, in most applications.

Wrong. Most of the important HPC/technical computational
kernels are well balanced between add/multiply - matrix
multiply, matrix decomposition, dot product, polynominal
evaluation, digital filter evaluation etc.
