 My hunch is that Intel's been suffering through some strategy tax or product segmentation tax for awhile. Obviously, Atom was created for Netbooks, so it naturally had to perform not as good as Core processors and relied on n-1 nodes to make them cheap. Then for 3 straight years, they tried to shoehorn the in-order core into a smartphone SoC. They got a couple of very minor wins (Razr i, Yolo), but I view those as more concept phones (read: concept car) then a serious...
 Maybe. I use 2 to 4 Watt to be safer, and it just feels more than 1 or 2 Watt based on the battery tests I've seen. I'm relatively certain you can burn down an iPad Air battery in 6 to 7 hours by turning the screen brightness down to the lowest setting (probably 1 to 2 Watts) and running a complex game or application. So, the SoC is probably hitting somewhere between 2 to 4 Watts. Lastly, 4 Watt TDP for the tablet is likely the limit due to skin temperatures, and it's...
 My take on benefits of 64-bit is that it's a holistic one for the consumer. The big benefit will be for developers (Apple software included) and customers get a downstream effect of better software. Virtual address space goes to whatever terabyte or exabyte levels it will be, instead of the 4 GB it is today. This will make it easier for them to make more complex software. So, for obvious things like video, 3D, big computation applications, developers can get going...
Intel is indeed a dangerous competitor, and could come up with quite a few wins for Merrifield in 1H 14. But what you list isn't proof. These are all tablets with 4 to 8 W TDP. Smartphones will be in 2 to 4 W TDP levels. Wait and see on whether Merrifield can compete with Snapdragon 805 next year.
 I'll take you on that bet. I'll bet that Samsung basically knew no more than Chipworks did. They didn't know it was 64-bit, and they didn't know any details of the CPU. They only thing they could really know was the generic type things Chipworks could identify. Things like "this looks like the GPU, this is where the CPU is, this looks like L1 cache, this looks like the memory bus" yes, but zilch on any architecture details. We only know scant architecture details from...
 Yup. People hanging on to the idea that since Samsung Semi fabbed Apple's SoCs, it was really Samsung who "built" the chip, and therefore can easily ramp up a 64-bit SoC on their own are pretty desperate for it to be true. It's like saying since Foxconn manufactures the iPhone, Foxconn will be able to ship their own iPhone in 6 months. The business relationships and the manufacturing process just don't work that way. To make a poor analogy, it's like saying the workers of...
Beautifully designed machine.
 Luck of the draw. It's the same display, but Apple's sourcing it from 3 different companies or so. There will be small variations in display performance from an individual companies line too, as well as variation among the different companies. Apple likely has a set of performance criteria for accepting a display or failing it. Inevitably, someone will get one that passed, but it was on the ragged edge.
 For those who don't know, Intrinsity, an Austin, TX based firm, traces it roots back to the PowerPC x704 in the 1990s. For those who weren't born or were still babies at the time, the PowerPC x704 was a high clock rate PowerPC processor (~500 MHz!) that they tried to sell to Apple for use in Apple PowerPC Macs. It caused quite the stir at the time as they were using an "exotic" biCMOS process to get those clock rates. Anyways, Apple killed Mac clones, and that basically...
As others have said, ARM SoCs can't improve 2x every year forever. ARM has run out of the low hanging fruit with the latest generation of CPUs where 3-issue out-of-order execution architectures were introduced with Krait, Swift and A15 cores. For a period of 4 or 5 years or so, ARM went from simple 1-issue, in-order, non-superscalar architectures to modern techniques (superscalar, wider issue widths, branch prediction, out-of-order, SMP) on a yearly cycle. They...
