- A12 has 8MB on chip “SoC cache”
- Big core L1$ = 128kB; Little Core L1$ = 32kB
- For the big core, L2$ is a whopping 128 instances 6MB per core/thread, 8MB at 64KB/inst.
- Little core L2$ is 32 instances, 1.5MB per core/thread, 2MB at 64KB/inst
- A12 GPU uses memory compression!
- A12 Big has 2.38 GHz base clock and 2.5 GHz 1 core boost
- A12 Little has 1.538 GHz all core, and 1.562 GHz 2 or 3 core boost, and 1.587Ghz 1 core boost
- A11 and A12 have a 7-wide decode (up from 6 on the A10) and 6Int ALU (up from 4 on the A10)
- Apple’s microarchitecture seems to far surpass anything else in terms of width, including desktop CPUs
- SPECint/fp Numbers show that it’s got 2x the speed of and any all other mobile SoC’s. 3x perf/watt if you normalize speed / power consumption.
- SPECint/fp numbers also show that the A12 is faster than a skylake server cpu (in core-for-core IPC). Not a perfect comparison, but far better than Geekbench
