Would be fun to compare 384 kepler cores(GT 730) vs 384 Maxwell cores(GT 940m) vs 384 Pascal cores(GT 1030)
However Maxwell 940m has ddr3 memory so its a bit slower than Kepler GT 730.
To get an idea 940m scores 2300 in 3Dmark11 while 730 kepler scores 2500,Pascal 1030 is expected to score around 4000 so around 60% better.
So 1.6 Kepler core= 1 Pascal core
