This doesn't make sense: "Bin 0 for average quality, Bin 1 for good quality and Bin 2 for very good quality. ... ... 30%, 60% and 10% of the GeForce RTX 3080's dies belong to the Bin 0, Bin 1 and Bin 2, respectively."
How can the 30% worst samples be rated as "average"?
And then we have the unrelated issue of all the samples with flaws that make them unfit for use in a 3080. I suppose there's an average of five to ten flaws per manufactured chip (1-2 flaws per cm^2). Redundancy in the chip design allows some of the flaws to be ignored, but the yield shouldn't be stellar.
