Windows 10 runs terribly on ARM

I hope Microsoft wasn't banking too heavily on Windows 10 on ARM competing with cheaper Chromebooks, because it's probably not in the cards. The performance simply isn't there, according to this article on SlashGear:
When it announced its Windows 10 on ARM, specifically on Snapdragon 835, thrust late last year, Microsoft emphasized power efficiency as the primary selling point. What it might not have disclosed is that those savings in battery life might come at the cost of a significant hit in performance. [...] Sadly, this Windows 10 on ARM sighting might be the worst we’ve seen so far.
This isn’t a case of Windows 10 on ARM vs Windows 10 on x86. It is, after, arguable that a quad-core Intel Core i7, even a fanless one, could outperform an octa-core Qualcomm Snapdragon 835 under certain condition. No, this is a case of Windows 10 on ARM versus, say, Android on ARM, running on the exact same chipset and closely similar hardware.
An Android device running on a Snapdragon 835 averages 2,200 on single-core and 7,700 on multi-core tests on Geekbench. Last week’s mysterious “Qualcomm CLS” device 1,202 and 4,263 on those same scores. This ASUSTeK TP370QL, in comparison, yields an embarrassing 889 in single-core performance and 3,174 in multi-core at its highest.
[...]
At this point, it isn’t clear where Microsoft wants to take Windows 10 on ARM anyway. It has all but lost interest in the mobile market, as far as pushing Windows 10 itself goes, and might be eyeing a very niche market for Windows 10 on Snapdragon-powered tablets, possibly for industry use. But with benchmark scores like that, it might be dead on arrival.
Ouch.

Intel wasn't at all happy about Windows 10 on ARM, which they saw as infringement of their x86 patents, but if these benchmarks are anything to go by, Intel needn't worry too much, since nobody will be buying ARM-based Windows 10 machines anytime soon. Whether they start buying x86-based Windows 10 machines again is still anyone's guess (although I still guess that they won't, because Moore's Law isn't a thing anymore).
