One notable aspect of the M3 Max chip is that it will be manufactured using a new 3nm process, offering potential improvements in both performance and power efficiency compared to the M2 series, which used a 5nm process.
While details about the specific device in which Apple is testing the M3 Max remain undisclosed, it is reportedly an unreleased MacBook model with the codename “J514.” This aligns with previous leaks suggesting a 14-inch MacBook Pro with the same codename.
