Ok now this is becoming mixing.
If Multitexturing happens when a card has 2 TMUs (logically), then why the heck is:
1)The single texturing results of current cards not even correct with their theoretical amount of pixel pipes?
2)Multitexturing tests yeild higher Mtexels for R300 cards when they don't even support MT, having 8 pipes with 1 TMU? Which logically would make point number 1 even all the more confusing?
I know the fillrate is calculated usually by the amount of pixel rendered per clock, times the clock frequency. So if the R9700PRO has 8 pipes and runs at 325MHZ, then why the heck does single texturing in 3dMark 03 yeild 1500 MTexels?!
Furthermore, when the so-called multitexturing test is there, the cards perform closer to the theoretical single texturing fillrate of 8*325= 2600 Mtexels, with 2270 Mtexels/sec.
So, not only are the cards not properly rendering, but they don't even reach the full theoretical fill rate at all, like the FX5800. Could anyone explain if my reasoning of fillrate calculation is right, and why is nothing making sense?
