This reminds me a lot of the processor clock speed arms race that desktop computing went through a few years ago. Mobile devices have the added constraints of heat dissipation and battery life. I'd love to have a quad-core 2.5ghz phone to develop games for but if I can't expect users to have more than 5 minutes of battery life then what's the point?
Yes, I read the article, but nothing was said about the conditions under which those power reductions happen. Is it 75% at max load? Probably not. Is it 75% to achieve the same data processing throughput? I'd believe that.
