Apple claims the AMX blocks are six times faster at matrix multiplication than the Apple A12's Vortex cores. The Lightning cores feature machine learning accelerators called AMX blocks. The Apple A13 Bionic features an Apple-designed 64-bit six-core CPU implementing ARMv8.4-A ISA, with two high-performance cores running at 2.65 GHz called Lightning and four energy-efficient cores called Thunder. 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 40% lower power consumption than the A12's. It appears in the iPhone 11, 11 Pro/Pro Max, the 9th generation iPad, the iPhone SE (2nd generation) and the Studio Display. ![]() The Apple A13 Bionic is a 64-bit ARM-based system on a chip (SoC), designed by Apple Inc. 6 ( ARM big.LITTLE: 2 "big" Lightning + 4 "little" Thunder).
