They increase the % of the good chips per wafer because they can use chips with 2 bad CUs.
It is like.
+ 50% of the chips have all the CUs good.
+ 25% of the chips have 19 CUs good.
+ 10% of the chips have 18 CUs good.
- 15% or the chips have less than 18 CUs good.
So disabling two CUs they can use up to 85% of the chips in my example... if they use just the 100% good chips they will use only 50% of the chips.
I made my numbers but is is like that but if the production is really good they can have chips only with 19 or 20 CUs good... so they can enable them in a late patch.
