The Neural Engine core count doubled from eight to sixteen, which Apple credited with an 80 per cent increase in machine learning performance. Apple quoted 11 trillion operations per second and did not state the numeric precision, a pattern it has never broken in any subsequent generation.
Apple A14 Bionic
Apple doubled the Neural Engine to 16 cores and quoted 11 trillion operations per second, without ever naming a precision.
