8MP vs 6MP is simple to calculate in terms of larger print sizes while maintaining same image quality
your print can now be ~15% wider AND ~15% taller with same absolute (dpi) quality level. If aspect ratio wasn't locked it would be easy to see the gain. You could make a print 33% wider, just like HDTV is 33% wider than the old 4x3 SDTV. I don't know how you can come up with "1 inch bigger" without specifing the original. and it would never be 1 inch bigger in BOTH dimensions if he aspect ration doesn't change it would be 1 inch bigger on one dimension and 1.5 inch bigger on the other or 0.666 ich bigger on the other. Cant be 1" on BOTH dimesions with same aspect ratio. As and example if you had 6Mp 4x6 print, with 8MP you could do roughly a 4.5 by 7 inch print with same absolute dpi. but if you start with 8x12 print, then obviously the 8Mp could do 9 by 14.

Definitely a slight improvement, in the real world, you can make a print 1 inch bigger in both dimensions before resorting to interpolation, presuming a print resolution of 320ppi (the accepted standard in my end of the industry) William Robb
