As expected, developers with early access to Apple silicon-based transition kits have leaked some early benchmark scores. And it’s bad news for Surface Pro X and Windows 10 on ARM fans.
According to multiple Geekbench scores, the Apple Developer Transition Kit—a Mac Mini-like device with an Apple A12Z system-on-a-chip (SoC), 16 GB of RAM, and 512 GB of SSD storage—delivers an average single-core score of 811 and an average multi-core score of 2871. Those scores represent the performance of the device running emulated x86/64 code under macOS Big Sur’s Rosetta 2 emulator.
Compared to modern PCs with native Intel-type chipsets, that’s not all that impressive, but that’s to be expected since it’s emulated. But compared to Microsoft’s Surface Pro X, which has the fastest available Qualcomm-based ARM chipset and can run Geekbench natively—not emulated—it’s amazing: Surface Pro X only averages 764 on the single-core test and 2983 in multi-core.
Right. The emulated performance of the Apple silicon is as good or better than the native performance of the SQ-1-based Surface Pro X. This suggests that the performance of native code on Apple silicon will be quite impressive, and will leave Surface Pro X and WOA in the dust.
