Apple M1X leak suggests MacBooks are in line for a major performance boost

The M1 successor could boast double the GPU performance.

An apparent benchmark listing for the so-called Apple M1X CPU may have given us a glimpse at next-generation Apple Silicon.

The leak shows an Apple M1X with 12 cores, according to CPU Monkey, an increase over its predecessor’s 8, which will reportedly arrive in the form of 8 highperformance ‘Firestorm’ cores coupled with 4 efficient ‘Ice Storm cores’.

The CPU will allegedly see an even more impressive upgrade in the graphics department. The leaked benchmarks, which are said to come from a “presample” of the M1X, suggests the processor will feature a 16-core GPU with 256 execution units.

The M1, found in Apple’s latest MacBook Pro and MacBook Air devices, features an 8-core GPU with 128 execution units, which suggests that its incoming successor could offer up to double the graphics performance.

The Apple M1X will also feature an increased TDP of 35W-45W, according to the listing, and support for up to 32GB of LPDDR4X memory and PCIe 4.0 storage.
