- If QuickTime were the only means of providing animation on a Mac, I'd
- agree with you. If the Amiga had software remotely approaching what QT's
- doing that was running faster than QT on a Mac, I'd agree with you. It's
- not, and it doesn't.

- No, it doesn't do better than the Quadra. You're taking two entirely
- different situations and comparing them. Show me an Amiga that can do 640
- x 480 8-bit video animations at 30 fps when updating every pixel on every
- frame. This requires a memory bandwidth of over 9 MB/sec. It's my
- understanding that the A4000's (the top of the line Amiga) bandwidth into
- chip memory is only 7 MB/sec, so it couldn't do this due to hardware
- limitations.

-
- Yes, what actually is the bandwidth into the A4000's video memory? If
- it's not at least 9 MB/sec., the A4000 can't animate 640x480x8 at 30 fps.
