It doesn't matter matter how fast you are, if you get hit hard enough by a well timed shot then you will go down. In the "real world" Muhammed Ali, George Foreman, and Mike Tyson proved that on a regular basis.
Against some insanely powerful people, Superman has done all out speed blitzes, and used his speed to dodge punches....also the OP says Superman is not holding back, so I'm assuming he's using all his powers to their full potential.
