The 68040 is the first member of the 68000 family with an on-chip FPU.
In Macintosh computers, the 68040 was primarily used in the high-end Quadra. The fastest 68040, clocked at 40 MHz, was used only in the Quadra 840AV. The more expensive models in the short-lived Centris mid-range also used the 68040.
The 68040 was also used in other personal computers such as the Commodore Amiga 4000, as well as in some workstations and the latest versions of the NeXT computers.
Heat was always a problem with the 68040, but its performance is four times that of the 68020 and 68030 at the same clock.
