Took so long I thought they might not be reviewing it.
As usual it's great to have a review that gets into the technical details which can give us a broader picture of Apple's strategy as opposed to another review that only covers the basic experience.
Footnotes:
- Wifi battery test is basically equivalent to the iPad Air. (Better on wifi, worse on LTE). Makes me wonder if the battery reports we are seeing are 'new device syndrome' or if the additional RAM is dragging down overall life through sleep drain which was not tested.
- Absolutely class leading cpu performance. Crazy how fast these are getting, and this explains why I am such an iPad geek. Looking at the browser tests, the iPad is a web browsing computer, perfected. It's now desktop class fast, and in my experience these optimizations actually make it faster and smoother than my i7 Thinkpad for general web browsing, including videos.
- the Imagination PowerVR GX6650 move from a 4 cluster layout to a 6 cluster, accounting for much of the 50% increase which brings near top of class graphics, and those ahead are largely devices dedicated to gaming.
- doubling the Ram doubles the memory Bus width to 128 bit and bandwidth to 25.6 GB/S which accounts for a further speed increase. This means the A8x should be bottle necked by memory bandwidth far less frequently than A7 even with the additional GPU clusters.
- NAND performance is class leading in sequential read/writes but just above average for random performance.
- the author believes that while the software is class leading, they are falling behind on extending the use cases for the iPad because they have such a comfortable lead. I somewhat agree. On the other hand, I think that Apple is so stretched for software development today that they'd be better served to slow down and polish what they are releasing a bit better before trying to pack in even more features.
