Not so. If you can use the burst transfer into the cache, and throw away the
line (i.e. burst dump it) when finished, its a very large win. Of course,
you need cache management instructions, and your graphics algorithms have to
have a pretty good idea of how much of a cache line they're going to munge.

For moving windows around, for example, you have a very good idea, and it pays.
