Exactly, that's what I was getting at. It's similar to Intel chip production and binning. Take Skylake for example: if a 4 core i7 chip had a core that didn't pass testing, they would disable the bad core and one more and process the chip as an i3. i5 chips were just i7 silicon with hyperthreading disabled. Same chip fab, same production cost, but the failed chips became a lower tier that sold for 35% and 70% of the top tier product. In the case of the PS5 chips, the performance difference between binned and pristine chips was even less, it still had 75% of the cores usable.
