Surface Pro 9 SQ3 Arm, 8GB VS Surface Pro X SQ1 ARM, 8GB
Fabulous performance by the 3 year older Surface Pro X but obviously couldn't hold of the might of the newer SQ3 ARM based chip in the Surface Pro 9!
Testement to what a great job that Microsoft have done with the emulation layer in Windows for ARM as both very resepectable results here.
