Apple has today unveiled its next-generation M6 Apple silicon chip, as well as a powerful M5 Ultra. The new chips will debut in new versions of its Mac Mini and Mac Studio, respectively, available to pre-order from today.
The M6 is Apple's first chip on a 2-nanometer process, utilizing a 12-core CPU with two super cores, four performance cores, and six efficiency cores. The chip also features a 12-core GPU and a 12-core GPU featuring neural accelerators, alongside a "Dual 16-core Neural Engine." The top version of the chip has 170GB/s of memory bandwidth.
That dual 16-core neural engine means that there are indeed two neural engines. There's a connection between the engines, allowing them to run one model quickly across both, or two separate models independently.
The M5 Ultra is Apple's first chip using its UltraFusion technology to form a quad-die architecture (The M5 Max chips it is connecting both used two dies). The chip goes up to 36 cores on the CPU and up to 80 cores on the GPU, with 1.2TB/S of unified memory bandwidth, which Apple says is 50% higher than the M3 Ultra. Apple also claims the 36-core CPU with 12 super cores and 25 performance cores will offer "up to 1.25x higher single-threaded performance and up to 1.3x higher multithreaded performance than M3 Ultra."
