Apple's A12Z Under Rosetta Outperforms Microsoft's Native Arm-Based Surface Pro X

Apple's Developer Transition Kit equipped with an A12Z iPad Pro chip began arriving in the hands of developers this morning to help them get their apps ready for Macs running Apple Silicon, and though forbidden, the first thing some developers did was benchmark the machine.

Multiple Geekbench results have indicated that the Developer Transition Kit, which is a Mac mini with an ‌iPad Pro‌ chip, features average single-core and multi-core scores of 811 and 2,871, respectively.

As developer Steve Troughton-Smith points out, the two-year-old A12Z in the ‌Mac mini‌ outperforms Microsoft's Arm-based Surface Pro X in Geekbench performance, running x86_64 code in emulation faster than the Surface Pro X can run an Arm version natively.

So the DTK with a two year old iPad chip runs x86_64 code, in emulation, faster than the Surface Pro X runs it natively 😅 Oh boy Qualcomm, what are you even doing? https://t.co/UAlZiwSsF8 — Steve Troughton-Smith (@stroughtonsmith) June 29, 2020

    The chip is installed in a Mac mini. They don't have to care about battery life, so they may have clocked it higher, added more cache and given it a deeper pipeline.

    Or, it is Microsoft for ARM. William of Ockham has a razor he would like to demonstrate for you.

      Will it shave off that horrible so-last-decade goatee?

        You confuse Ockham with Hanlon, whose razor may also be applicable in this situation.
