"What might be "acceptable yields" for a 120mm^2 CPU may not be acceptable for a 230mm^2 CPU in an increasingly competitive pricing environment."

It isn't an issue of yields. In fact, because the increase is purely in a structure that is protected with redundant cells, the percentage of die lost due to defect density will be lower with the larger caches.

Now a 230 mm^2 die means about 250 die candidates per wafer. 183 mm^2 dies means about 330 die candidates. So that is the equivalent of increasing production by about 30%.
