This is binary compatible with the upcoming A15 processor, but lower speed and more power efficient. The intent is that a chip will have some A15 cores and some A7 cores and use them as appropriate to balance speed and energy consumption.
It could also be used as a standalone processor where its performance is sufficient and energy efficiency is a win.
The "Cortex A∗" numbering scheme should not be confused with the "Apple A∗" numbering scheme. They are unrelated. There is in fact an A5 in each scheme at the moment.
- tiles 15y agoI wanted to bring up, the numbering scheme has always been awkward to me, and I'm wondering what will happen when Apple releases the A7, if they'll just let the confusion continue... Was this an intentional move on Apple's part or just not something they paid attention to?
- sliverstorm 15y agoMy guess is not intentional. I would bet they called it the "A"4 because they are "A"pple.
- derefr 15y agoThat—and I always figured it was a bit of a joke. The iPad was the first device to ship with the A4 chip. The iPad is a sort of digital ...pad of paper. And what's the smallest standard size of paper that fully covers an iPad? (Basically, the kind of envelope you'd buy to put an iPad into?) A4.
- ori_b 15y agoIt doesn't help that the instruction set version is numbered similarly, but their numbers are not the same as the chip version.
