Apple’s new M1 processor can run the ARM version of Windows 10 faster than the processor that comes in Microsoft’s Surface Pro X series.

This is based on theoretical measurements because the Arm version of Windows 10 is currently not officially licensed for Apple’s M1 processor. However, developers have managed to virtualize Windows on an M1 Mac using the QEMU service, reports Windows Latest.

When running the ARM version of Windows 10 the M1 processor sees impressive Geekbench scores: a single-core rating of 1,390 and a multi-core rating of 4,769.

This can be compared to the Surface Pro X, which instead gets 802 in single-core rating and 3,104 in multi-core rating. 

Surface Pro X uses a specially built ARM processor in the form of Qualcomm’s SQ1.

Both Microsoft and Qualcomm are expected to present new ARM hardware during the first half of 2021.
