- Basically. We quote bandwidth increases because they tell how much faster
- a particular thing is, independent of how it got that fast. in the case of
- the AA chips, 2x improvement is gained by doubling the word size, 2x by
- doubling the amount of data fetched per bus cycle (two data fetch cycles run in
- the space of one ECS data fetch, much like "burst" modes in other systems).
