Super Agnus supports 2 MB of Chip RAM, whereas the original Agnus/Fat Agnus and subsequent Fatter Agnus can address 512 KB and 1 MB, respectively. The ECS Denise chip offers Productivity (640×480 non-interlaced) and SuperHiRes (1280×200 or 1280×256) display modes (also available in interlaced mode), which are however limited to only 4 on-screen colors. Essentially, a 35 ns pixel mode was added plus the ability to run arbitrary horizontal and vertical scan rates.
