They compare it to the A12 I think because the iPad Pro and previous iPad Air (I believe, can’t remember) were both running A12 variants. It may still have something over the A13, but if they are trying to convince people to upgrade they probably want to compare it to the previous gen.
- hajile 6y agoThe issue is more fundamental. Apple hasn't made any computing breakthroughs. They got a lot of gains by going super-wide to extract obvious parallel performance. They are now at the point where adding more units costs more than it offers (at present). Their fundamental advantage over x86 is that aarch64 is less quirky, so implementing good ideas takes less time. Their only "easy" dial left is ramping clocks, but that's linear power scaling, so it doesn't matter too much for their portable electronics. I'd guess they'll be focusing a lot more on data locality and caching. It's probably 5-10% gains every couple years from here on out.
- jonplackett 6y agoI think this was borne out pretty well with the announcement. Most of the 'breakthrough' tech enabled by A14 was just stuff the A13 could already do just fine. They spent about 10 minutes talking about deep fusion FFS. (still buying one though...)
- egsmi 6y agoDo you have any reference for that? I am very curious how the "width" of an Apple cpu was measured. One of the few good measurements I know of was done here and it's a bit inconclusive as the result is very particular. https://news.ycombinator.com/item?id=18442131 https://news.ycombinator.com/item?id=18442131
