What is sharper

So what is sharper?
smc PENTAX FA 50mm F1,4
Nikkor AF 50mm F1,8 D

I think that the nikkor is sharper.

The test results at photozone indicate that the Nikkor has better center sharpness at f/2 but marginal border sharpness until f/4. The Pentax is sharper overall beyond f/4.

Nikkor AF 50mm f/1.8 D - Review / Test Report

Pentax SMC-FA 50mm f/1.4 - Review / Lab Test Report

Having made the comparison, it is good to remember that photozone cautions against comparing lenses cross-platform. It is probably enough to conclude that both lenses represent substantial value for the money and that both are better than the substantially more expensive Nikkor AF 50/1.4.

The nikon is probably sharper wide open, but unfortunately has terrible bokeh. So does the Nikon 50mm f/1.4. Hopefully Nikon's new 50mm lens fixes that. Check out Welcome to Photozone! for lens resolution tests. You can't compare the different systems exactly, but it gives you a rough idea.

lenses optimized for wider apertures usually need to be more stopped down to get sharp
