Not necessarily. According to Henry Spencer the 68030 can run a BitBlt in
cache fast enough that there's one useful memory reference every clock cycle.
This is also the maximum speed a DMA device can be expected to support. Thus,
a 68030 cannot be speeded up by a Blitter. See the blitter wars in comp.arch
for more details.
