Jeg ved ingenting, men jeg tror ikke på Tim Cook ville gå med til at sælge defekt hardware

Noget lignende har vi for nyligt set med A12X vs. A12Z:
https://www.macrumors.com/guide/a12z-vs-a12x/
"Evidence from teardown site TechInsights indicates that the A12X chip physically has an 8-core GPU with one of the cores disabled, which means the A12Z is the same version of the chip with the disabled core enabled.
It's not unusual for chip manufacturers to render one core of a processor inoperable when it isn't meeting yield levels, and that appears to be what Apple has done now. The manufacturing of the A12X chip has improved enough that yields have gotten better and all 8 cores are functional."
Som sagt: Det er helt normal praksis.
