The tubes that make up the core are dimpled, this creates more surface area inside the tube. It also will force more turbulence in the flow thru the tubes. That will help prevent a boundary layer in the tube and expose more coolant to the surface of the tube to allow better heat transfer. A high density(or high efficiency) core has the tubes closer together, allowing more tubes per row, and will normally have more fins per inch. Also available is a core with seamless or welded tubes, no soldier seam in the tube to corrode. Something else to look at is the fins, are they flat or do they have louvers in them(better) have to look very close!
