According to 9to5Mac, unnamed “independent sources” have confirmed that Apple’s upcoming 13-inch and 15-inch MacBook Airs will be powered by the M3 chip. The source further claimed that both devices will only get the base M3, and not a more powerful version of it, like the M3 Pro, for instance.
The M3 is expected to come with an 8-core CPU like the M1 and M2, so it isn’t immediately clear how it will differ from those two chips. The report further claims that while the 13-inch model is codenamed J513, the 15-inch variant is codenamed J515.
