12-Core Apple Silicon ‘M1X’ Supposedly Leaks, Surpasses M1

| 26 days ago


It’s been just over a week since Apple launched its M1 processor, and it already looks like a successor has been spotted.

Speculatively dubbed the ‘M1X’ from LeaksApplePro on Twitter, this next SoC (System on a Chip) from Apple is expected to double up on the number of high-performance cores found in the M1.

With a 12-core CPU—eight high-performance cores and four high-efficiency cores—the benchmarks could reveal double the performance or more.

In real-world use, the M1X’s main competitor in terms of speed will be its little brother, the M1.

No processor previously found in MacBooks has come close to the level of advancement brought about by the 5nm M1. In terms of specs, the M1’s CPU comprises four high efficiencies Icestorm cores and four high-performance Firestorm cores.

It brings an integrated 8-core GPU and 16-core Neural Engine that makes macOS absolutely fly. With the operating system able to access the full amount of memory, performance is much more consistent and snappy.


Currently, the M1 is used in the MacBook Air 13-inch, MacBook Pro 13-inch, and the new Mac mini. None of these models seem to sport drastically different designs.

However, after rumors emerged today from Ming-Chi Kuo and Twitter user L0vetodream, MacBooks available in late 2021 could see a design update. Hopefully, this means thinner bezels and innovations from the Cupertino-based tech giant.

The promise of an ‘M1X’ should take those improvements a step further. The hypothetical processor is said to first power the 16-inch MacBook Pro, which, according to LeaksApplePro, will arrive in the first quarter of 2021.

Other enthusiasts, including David Eden-Sangwell on YouTube, believe the M1X could be the larger processor meant for desktops like the rumored miniature Mac Pro.

While neither of these release options seems to line up with the rumors from Kuo and L0vetodream, it’s possible that this 16-inch MacBook Pro isn’t part of the lineup that will be receiving a new design.

With Q1 2021 just a few months away, we should have answered soon.
