Very interesting anandtech article on the A7 soc
A very insightful read as per usual from Anand, what I find most interesting is the implications going forward for a possible move away from intel on the osx side of things, I'm just speculating here, but I could see it happening eventually. Fta;
'I also noted an increase in overall machine size in my initial tinkering with Cyclone. Apple's LLVM commits indicate a massive 192 entry reorder buffer (coincidentally the same size as Haswell's ROB). Mispredict penalty goes up slightly compared to Swift, but Apple does present a range of values (14 - 19 cycles). This also happens to be the same range as Sandy Bridge and later Intel Core architectures (including Haswell). Given how much larger Cyclone is, a doubling of L1 cache sizes makes a lot of sense'.
'Unfortunately I don't have enough data on Swift to really produce a decent comparison image. With six decoders and nine ports to execution units, Cyclone is big. As I mentioned before, it's bigger than anything else that goes in a phone. Apple didn't build a Krait/Silvermont competitor, it built something much closer to Intel's big cores. At the launch of the iPhone 5s, Apple referred to the A7 as being "desktop class" - it turns out that wasn't an exaggeration'.
The last quoted paragraph brings home for me just how juvenile the whole 'apple is no longer innovative' tired meme has become, I wish some of apples competitors would lay off the fud for a while and concentrate more, we'd all benefit in the long run. Also there was this little tidbit from tidbits about running mavericks on an ipad air, albeit with very limited functionality, which also speculates about apple using its a-series soc for osx based hardware.
