-*M5 ANE TOPS not officially disclosed; ~19 TOPS estimated from measured peak.
+*Apple's "Rated TOPS" changed methodology across generations — M1/M3 report FP16,
+M4 reports INT8/mixed-precision peak. The numbers are not directly comparable across
+generations. Use the measured FP16 TFLOPS column for apples-to-apples comparison.
+All chips have 16 NE cores except Ultra variants (32 cores, two dies via UltraFusion).
+Max variants share the same 16-core NE as Pro — the M4 Max vs M4 Pro TFLOPS difference
+is run-to-run variance, not hardware.*
