> For Windows, binary compatibility with 3rd party apps is extremely important, at least for the apps that aren't browsers running JavaScript, so, what Qualcomm could aim to do is to optimize the heck of their ARM offerings for x86 emulation/JITing, and efficient JavaScript execution, more or less what Apple did.
I found this remark by HN user dwaite very informative: https://news.ycombinator.com/item?id=37327938 https://news.ycombinator.com/item?id=37327938
TL;DR emulated x86-32 performance on ARM is poor, and is going to stay poor because of the memory model. Whether this strategy is going to be successful largely depends on how important/prevalent legacy 32bit apps are.
