rank 14 of 16 — the clock-independent number

What every operation costs

Every numeric type, all five operations, as clock cycles per operation: the shape of this part's cost independent of its clock. The bars are the story of where it falls off a cliff — divide, 64-bit, floating point.

The same cells as nanoseconds per operation, median of three samples. Darker is slower; the small number is this board's rank in the fleet for that cell (1 = fastest of 16).
