Rosetta 2 Benchmarks Surface From Mac Mini With A12Z Chip

Rosetta 2 Benchmarks Surface From Mac Mini With A12Z Chip

A week ago, Apple spelled out its plans to move to its own ARM-powered chips for future Macs.

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.

As part of the move to ARM chips, Apple is distributing Developer Transition Kits (DTKs) to developers, with an eye toward helping them get their apps ready for the new Apple Silicon Macs.

Even worse, the version of Geekbench 5 on the Mac Mini was running under Rosetta 2, Apple's x86 emulator for ARM, while the Surface Pro x was running an ARM-native version of Geekbench 5.

Multiple Geekbench results have indicated that the Developer Transition Kit features average single-core and multi-core scores of 811 and 2,871, respectively. For instance, Apple used Intel Pentium CPU's in DTK in 2009, however, they switched to much faster Intel Core i CPU's in the final product. It's also worth noting that Rosetta 2 appears to only use the A12Z chip's four "performance" cores and not its four "efficiency" cores. As far as clock speed is concerned, the A12Z is clocked at 2.4GHz.

13-inch MacBook Pro scores uploaded today using macOS 10.15 Catalina and an Intel Core i5-1038NG7 are seeing single-core scores around 1,200 and multi-core scores around 4,400, but those aren't using emulation.

During last week's Worldwide Developer Conference, Apple CEO Tim Cook announced that his company would ship its first Silicon Mac by the end of 2020, though there's no official release date for the hardware just yet.
