WRONG! Do your homework, I have.
The Amiga 2000 is 24 bits wide, not 16 bits.
The reason why an Amiga 2000 will usually be faster then and Amiga 3000 or 4000, both using the same processor, is because the Amiga 2000 does not have a Super Buster chip, which is a bottle-neck on the Amiga 3000 and 4000 machines.
Amiga2000 is 24bitaddress, which provides for 16MB total address space. This has nothing to do with speed, only with size. Amiga2000 has 16 data bits, this is what has to do with speed.
SuperBuster may be a bottleneck between the CPU and the Zorro3 slots, but if not accessing Zorro cards, I'm not sure what it has to do with anything.
