Every recipe that produces Encased Industrial Beam, compared at 100% clock speed on a single machine.
“Encased Industrial Beam” in an Assembler makes the most per machine, 6.00 items/min. Per unit of Concrete, though, “Alternate: Encased Industrial Pipe” is the one ahead instead: 0.200 against 0.167, a gap of 1.2×.
Rates per minute are given at 100% clock speed. Solids are shown in items/min, fluids and gases in m³/min. Output per MW compares the step on its own; it excludes the power used upstream and by extraction.
