Damn--- if they double it again for the iPad5, it'll be getting close to my old macbook pro in geekbench.
I just checked, and apparently it's only 640 points slower than *my* old (not current) MacBook Pro (2006 - 2Ghz CD).
That really put it into perspective! In fact, it'll only take 2 doublings for it to clean the clock of my *current* MacBook Pro (2010 - 17" 2.8GHz i7).
4th Gen iPad:1757
My first MacBook Pro: 2397
My current MacBook Pro: 5802
So, 2012 ARM is close to 2006 Intel, and (extrapolating) a 2014 ARM will be better than a 2010 Intel. Going just by this metric, it puts the CPU-power cross-over for Intel vs. ARM somewhere around 2016! It probably won't be the case in reality, but it's certainly not going to be too long before ARM CPUs are perfectly suited for normal peoples' desktop needs. (Heck, they might actually be there already, since an iPad will actually do most/all of what most normal people need out of a computer.)
