With numerous rumors talking about the resurrection of the 12-inch MacBook, one major difference is that this model will reportedly feature the company’s custom silicon, or in this case, the A14X Bionic, according to the latest info. Strange enough, this chipset is also said to be found in the new iPad models, but a tipster claims that it will be found in the 12-inch MacBook, transforming it into one powerful and portable machine. There are other rumored hardware specifications of the 12-inch MacBook, so let us talk about them in more detail.

A tweet from tipster Komiya highlights the internal specs for the upcoming 12-inch MacBook. This model is said to be offered in 8GB or 16GB RAM configurations, along with 256GB, 512GB, or 1TB storage options. One of the biggest selling points of the ARM-based 12-inch MacBook is that it is said to offer between a whopping 15-20 hours of battery life, and that’s a major step-up compared to the 8-10 hour endurance you’re getting with Intel-based MacBook models.
