- Actually, the blitter runs at 7.14 MHz. Even in an A4000. The only difference
- is the 32 bit wide data path in the newer machines.

-
- I don't know exactly about the A4000, but in the A3000 the CPU is faster than
- the blitter. That's the reason a program named 'CPUBlit' exists. Even on my
- A2000 with it's 16 bit data path, the A2630 + CPUBlit is a little bit faster
- than the Blitter.
