Previously, when the ARM-based 12-inch MacBook specifications were provided by a tipster, the details mentioned an A14X Bionic SoC, which we believe is the same silicon expected to be found in the new iPad Pro models that will also provide 5G support. However, things have taken a different turn here because a different individual who goes by the name Jiorīku claims that the first ARM-based MacBook will feature a completely different chipset.

On Twitter, Jiorīku believes that the upcoming machine will not feature an A-series chipset that we’ve all known to come and love. Instead, it will be a completely different silicon sporting a new name. However, we’d like to think it as a chipset that may be a slightly altered version of the upcoming A14X Bionic that’s tailored to fit inside the chassis of a MacBook, not an iPad Pro. This can mean that the die size may be bigger than the size of the silicon running in the new iPad Pro models.
