Apple publishes no throughput figures for M-series silicon. Its technical specification pages give GPU core counts, Neural Engine core counts and memory bandwidth, and no FLOPS of any kind, while its newsroom compares generations only in relative terms. The FP32 figure shown here is the one Apple quoted for some M1 and M2 family chips and is otherwise third-party, so it is recorded as a claim rather than a specification. No FP16 or INT8 figure is listed: Apple publishes neither, and an INT8 rate derived from GPU FP32 would in any case describe the Neural Engine, which is a separate unit Apple rates in TOPS.
