Apple’s DTK development kit, the Mac mini with the A12Z bionic chip, has reached the hands of many developers, and we’ve seen the A12Z run. Based on Geekbench’s multiple running points, the DTK A12Z has a single-core average of 811 and a multicore average of 2871.
According to developer Steve Troughton-Smith, the A12Z chip on the Mac mini was Apple’s two-year-old work, but its performance has already beaten Microsoft’s ARM chip Surface Pro X, and the A12Z is still translated from Rosetta 2 x86_64 code. Surface Pro X runs native ARM apps.
Microsoft’s Surface Pro X’s Geekbench runs a single-core 726, multicore 2831, which means the A12Z single-core surpasses Surface Pro X and is slightly higher than surface Pro X.
Surface Pro X features a Microsoft-designed 3GHz ARM chip based on qualms on the Qualcomm SQ1 chip. The A12Z chip in the Apple DTK is the same as the A12X in the 2018 iPad Pro, but turns on an extra GPU core.
In the future, ARM chips that will appear on Mac computers will be developed based on the A14 chip, which will debut on the iPhone in 2020 using a 5nm process.
Apple says its self-research chips offer higher performance and better energy efficiency.
