@NorthWay ye I saw some of those, but those threads tend to be a bit too technically specific for my taste.. like two guys arguing over 6 pages about dma cycles in a specific scenario or something like that. ,-)
This text below is from the good old Natami page. No idea who wrote this but st least it was someone with better knowledge about AGA than me ;-) (which isn't that hard, btw) .
COPPER: including original AGA copper
Fully compatible with AGA-AMIGA
Speed of SuperBlitter is many times faster than AMIGA AGA blitter
comparisons will follow.
In Chunky/Hicolor/ or Truecolor pixel mode the Super Blitter can "cookie cut" copy BOBs.
Like the AMIGA Sprites, a "cookie cut" copy needs no blitting mask.
This enabled the blitter to use less memory and to work at double speed compared to planar blits.
Texturemapping Blitter enhancement.
Provides Mipmapping, Subpixel 4 way interpolation, Light sources, Antialiasing, Alpha blending.
