But what effect do they have in the end? That is what I am getting at. The concentrations are different, but the quantities are not the same either, so you really cannot compare them like that, what change do they make on the chemistry of the water?

Wow! We've sorta' hijacked the thread but to clarify a little:
1 lb of Cal Hypo will raise Cl 8ppm in a 10k pool
1 gal of 6% bleach will raise the same pool 6ppm
With bleach, you get almost nothing unwanted except a little salt
With Cal Hypo, you'll add a fairly good amount of Calcium which you may or may not want.
I'm making some assumptions here that I'm not sure are absolutely accurate, but this is close enough for g-work.
Using about 8.3 lbs/gallon of water, a gallon of 6% sodium hypochlorite bleach should contain about 8 oz. of sodium hypochlorite. A pound of calcium hypochlorite at 65% should give you about 10.4 oz of the calcium hypochlorite. As someone else said, about 25% more active ingredient in the cal-hypo.
I had some of the same questions. This thread may help you:
