Wrongo.  ** PLEASE IF YOU ARE GOING TO POST SOMETHING, BE SURE OF YOUR FACTS
OR WARN US YOU ARE SPECULATING **

The ST interleaves processor with coprocessor bus accesses just like the Amiga
does.  So you might have said:

The bus speed of the Amiga is 14.4 MHz as opposed to the ST which is 16 MHz.
The Amiga's 68000 runs at 7.2 MHz while the coprocessors use the other
7.2 MHz, compared with the ST's 68000 which runs at 8 MHz while the
coprocessors use the other 8 MHz.

(But saying a bus runs at X MHz means nothing.  You might want to say that
 the Amiga can transfer 16 bits of information in 280 ns, while the ST can
 transfer 16 bits of information in 250 ns.  This doesn't mean the ST is
 better than the Amiga, either, since (I am not sure) the Amiga might be
 able to do a graphics transfer in the "chip memory" at the same time as a
 processor transfer in the "expansion memory", giving higher throughput.
 But only for Amiga owners with expansion memory).


Boo hoo.  I paid $800 US for a fast computer with 1 meg of memory, 720K disk,
and lovely 640 x 400 non interlaced monitor.  Boo hoo hoo.
