[5] Apple states that the two high performance cores are 20% faster with 30% lower power consumption than the Apple A12's, and the four high efficiency cores are 20% faster with 30% lower power consumption than the A12's.

[6] The Apple A13 Bionic features an Apple-designed 64-bit six-core CPU implementing ARMv8.4-A[1] ISA, with two high-performance cores running at 2.65 GHz[7] called Lightning and four energy-efficient cores called Thunder.

The Lightning cores feature machine learning accelerators called AMX blocks.

[3][7][9] It is manufactured by TSMC on their 2nd generation 7 nm N7P (not to be confused with '7 nm+' or 'N7+'),[10] and contains 8.5 billion transistors.

It has decoding support for HEVC, H.264, MPEG‑4 Part 2, and Motion JPEG.
