唔係咩16*3...
呢個rumour要準確D表達pipeline configuration係

16 - 1 - 3 - 1

16 is 16 pipelines
1 is single texture per pass(up to 16 textures for 16 pipes)
3 is 3 fragment(pixel) per pass(up to 48 pixels for 16 pipes)
1 is single Z sample per pass(up to 16 Z samples for 16 pipes)

所以話根本16*3唔可能=48*1

NV47(G70)既pipeline configuration係

24 - 1 - 3/4 - 1 1/4

24 is 24 pipelines
1 is single texture per pass(up to 24 textures for 24 pipes)
3/4 fragment(pixel) per pass(up to 16 pixels for 24 pipes)
1 1/4 Z sample per pass(up to 32 Z samples for 24 pipes)

NV40既pipeline configuration係

16 - 1 - 1 - 2

16 is 16 pipelines
1 is single texture per pass(up to 16 textures for 16 pipes)
1 fragment(pixel) per pass(up to 16 pixels for 16 pipes)
2 Z sample per pass(up to 32 Z samples for 16 pipes)

所以NV47(G70)其實效率減低左DD, 換來既係D附加功能, 例如Gamma corrected AA/Transparent AA等等...

R520既pipeline configuration係

16 - 1 - 1 - 1
