We’re still a long way away from hearing anything official about Apple’s next system-on-a-chip. The A13 is likely to be unveiled in September, along with the new iPhones it will power. But the design, manufacture, and testing of these chips takes years, far too long for Apple to suddenly make radical changes. The A13 design is likely, for all intents and purposes, set in stone by now.
By looking at past A-series chips and extrapolating from what we know of the manufacturing process Apple will use this year, we can get a reasonable picture about what to expect from the A13 chip. It will almost certainly be the fastest SoC Apple has ever developed for iPhones, but exactly how fast can we expect?
