| Peak FP32 rate cpu | not applicable The 68000 has no floating-point hardware on the die. Floating point requires a separate 68881 or 68882 coprocessor, which the Amiga 500 does not have, so any floating-point rate would describe software running on an integer ALU. | Not stated | Vendor-rated | Theoretical peak Stated by the vendor |

Editorial notes
The split between the register width and the external data path is why the register width alone describes it poorly. The address space is larger than the memory fitted to the Amiga models in this catalog. Floating point is not on the die; it needs a 68881 or 68882 coprocessor.
