Benchmark of Apple’s New ARM Mac-Based CPU Appears

Apple developers allegedly have started receiving its Apple ARM transition kits, and now some reference numbers for those development kits have also appeared in the wild. Sighted by 9to5Mac, the benchmarks for the Developer Transition Kit appeared to have appeared on Geekbench, despite strict confidentiality clauses in the developer agreement that prohibit the execution of benchmarks.

There will be many eyes on the benchmarks released for the new Bionic A12Z CPU intended for macOS. While Apple showed it at WWDC, didn’t actually show his performance in super tangible ways. Most estimates of its performance have been based on the Bionic A12Z chip found in the latest iPad Pro. But rumors suggest the chips are not identical. Unfortunately, Apple hasn’t gone into detail about the structural differences between the CPUs, either.

There are some caveats about these new numbers available on Geekbench. It seems that development kits only run on four cores instead of rumored twelve that will be available in the product when it ships, and I assume those four cores are the dedicated performance cores (the product, when shipped, is rumored have eight out of twelve dedicated to performance).

If true, that could partly explain why development kit scores are lower than those of the iPad A12Z: Geekbench takes into account the four energy-efficient cores in the iPad A12Z, while the silicon development kit Apple lacks those cores. The highest score for New Apple Silicon at the time of writing this is 844 for single core and 2958 for multi-core, while a 4th generation iPad Pro he got 1118 for single core and 4726 for multiple core. The iPad A12Z also operates at a higher frequency, 2490 MHz, compared to the 2400 MHz development kits.

9to5Mac says dev kits run Geekbench 5 non-native via Rosetta 2, which might explain the ‘VirtualApple’ nickname listed in the Processor Info section, but it’s odd that Geekbench 5 runs via Rosetta 2 since there is already an ARM version of for iPad.However, iPad runs iOS on ARM, so Geekbench 5 may still need to run Rosetta 2 because there is still no macOS ARM version of the reference software.

Beyond the iPad, the closest thing we have to compare to the alleged development kits at the moment are the Intel cores, specifically a Intel Core i5-1038NG7 (4 cores, 2000 MHz) since mid-2020 MacBook Pro. According to Geekbench 5, one of the highest single-core scores is 1244, and one of the highest multi-core scores is 4526. That Intel core runs 400 MHz less per core than Apple ARM development kits, and it has the same number of cores, however its performance is leaping. Again, this could be because Geekbench 5 is not optimized for Apple’s silicon on macOS. Or it could be for him difference in how Apple ARM and Intel processors execute instructions.

Future Apple ARM processors are supposed to be upgraded versions of the A12Z, purportedly 12-core with eight dedicated cores for performance, which will definitely help Apple’s silicon compete against Intel and AMD. Judging from these numbers, you will need those additional cores. The first ARM Macs should appear At the end of this yearBut Apple will still launch new Intel models even after the transition begins, and its Intel devices should be compatible for at least five years from now. So if you are thinking of getting a macOS device, it may be smart to get it now.
