The M1X will be the next step towards Apple’s transition to using custom silicon for its Macs, and like the M1, we should be impressed with what it has to offer. Just like its previous SoCs, Apple is said to be launching the upcoming chipset in two variants, and unlike the M1, that difference could be more pronounced and might result in delivering the biggest performance improvements.

Where the M1 was offered in 7-core and 8-core GPU configurations, the M1X could arrive in 16-core and 32-core configurations, according to Bloomberg’s Mark Gurman. While the reporter does mention that we should expect Apple’s redesigned MacBook Pro models later this month, MacRumors does not mention if customers will have a free hand in configuring both the 14-inch and 16-inch variants with top-tier chipset specifications.
