I've said it before and will say it again,... Once ARM gets dragged into a competition on performance,... They are dead meat. Their entire success has been in fine tuning power efficiency around a design point where performance was moderate at best.
Move them off balance where they have to scale performance in order to compete, and their power efficiency will then become their Achilles heel, no longer their strength and selling point.
Intel has been designing power efficient solutions that have been centered around much higher and more upward scalable performance design points. Have been doing this for the past decade and a half. Now we are laying the track for good scaling power/perf downward as well, both in architecture and process technology.
I say good luck to all who have bought into the ARMH hype, and please be careful with your kid's college fund savings. I won't accuse you of being a snob for having aspirations for your kids to get a higher education and make something of themselves.
