Hello community! As I read from https://support.apple.com/kb/SP743?locale=en_US iPhone7 has A10 Fusion chip, which has 4 cores, but [NSProcessInfo processInfo].processorCount returns 2. Also here it is stated that "Unlike most implementations of big.LITTLE, such as the Snapdragon 820 or Exynos 8890, only one core type can be active at a time, either the high-performance or low-power cores, but not both. Thus, the A10 Fusion appears to software and benchmarks as a dual core chip. " Another source tells us that: "Meanwhile it should be noted that while A10 technically has four CPU cores – the two Hurricane cores and the two smaller cores – this is not a heterogeneous design, and only two cores are active at once. So for the purposes of high performance benchmarking, this means we're benchmarking the big cores nearly exclusively."
Can anybody confirm this or give the link to apple documentation to prove that?
Thanks!
