I learned this lesson the hard way during the AMD Phenom era. Core count are not a good representation of performance because the 8 "big" cores could be blazing fast or be secretly powered by a hamster on a wheel. What is the actual benchmark performance on real applications you might use? Thats what matters at the end of the day.
Having worked with Windows on ARM in the past, I _hope_ you're right. But my experience has been that a ton of code is still going through the x86 emulation layer, which IMO is woefully lacking in performance, particularly compared to Apple's Rosetta 2 (which is a magical marvel of engineering).
