   Graphics Card/AGP questions
  Okay, my googling skills seem to fail me.First for the graphics chips:Does "Fixed-Function"/"Fixed-Function Pipeline" just mean hard-wired functions ? or is it something else ?Now AGP:How do AGP 4x and 8x work (just in general, I don''t really need the evil details ;/ ) ?AGP 2x transfers data on both the raising and the falling edge of the clock, right ?But how did they manage to double/quadruple even that rate, without raising the clock-frequency (or did they ?) ?And then one last question. Does anyone have some kind of block diagram of a graphics card, with just things like bus-interface, vram, gpu and the ramdac on it ? Or if block diagram is just a term not commonly used for these things pointing me in the right direction would also be great If someone can give me some help, then that would well.. really help me. 
  Fixed function means that all the functions are hard-wired. So no programmable parts. No vertex shaders and pixel shaders.I don''t know about the inner workings of AGP but AFAIK the 2, 4 and 8 indicators are just speed indicators.I''m not a guru on this. Sorry.

Using the forums as a personal search engine seems moot.eVGA Article about the AGP3.0 specnVidia''s quick-sheet about AGP 3.0 - please note the sidebar link to a 2 meg PDF with further details.
