AnandTech on Apple's A7 processor:

I suspect Apple has more tricks up its sleeve than that however. Swift and Cyclone were two tocks in a row by Intel's definition, a third in 3 years would be unusual but not impossible (Intel sort of committed to doing the same with Saltwell/Silvermont/Airmont in 2012 - 2014).

Looking at Cyclone makes one thing very clear: the rest of the players in the ultra mobile CPU space didn't aim high enough. I wonder what happens next round.

This is one area where Apple really took everyone by surprise recently. When people talk about Apple losing its taste for disruption, they usually disregard the things they do not understand - such as hardcore processor design.

Note that even though the transition from 32bit to 64bit address space was quite boring in x86 and ARM, it doesn't *have* to be this way: in the Mill project they use the 64-bit address space to have unified address space (but still with memory protection) which allow them to have to more efficient memory subsystem ( ) and yes not be restricted to a tiny TLB is very important (think about the advantages for multiple processes).

I think that it would be great also if CPUs would use 64-bit pointer to allow you to have efficiently a tag field in the higher bits (which has benefits over using the lower bits as it is compatible with packed data(unaligned)) for tagging pointers (efficient GCs), tagging integers (efficient big-ints implementations)..
