Can someone please explain to me what ROPs are? My gpu has 16 of them. don't worry, before i asked here i tried to search for the answer but found nothing..

I searched wiki and it gave me a list of possible answers. This is the closest thing I could find: "Raster OPerator, a raster graphics function used (per pixel) in a Bit blit operation to combine two or more bitmap, perhaps on a GPU." What that means exactly, I have no idea.

A Raster Opterator - basically, they're the final stage of pushing pixels to your screen. Larger numbers of these are fairly unimportant compared to other pipelines, since they spend a lot of their time idle waiting for pixels to push.

ROP is an acronym for "Raster Operation Unit" or "Render Back-End Unit".

Both ATi and NVIDIA employ these units into their GPU architectures, but obviously, both companies implement ROP's differently.

To put it simply (I mean very simply): ROP's are the units that perform tasks such as colour tests, filtering and AA.

I recommend that you visit www.beyond3d.com and head to their forums if you wish to learn more about ROP's. They have some very knowledgable people there (people even in ATi/NVIDIA visit there), and will be able answer any questions regarding 3D computing that you have.

LordEC911 knows a fair lot about 3D technology too, so if you're lucky, he may be able to help here. But chances are he's busy digging dirt on NVIDIA's G100/GT200 or AMD's R680/R700. That, or he's busy bluffing his way in a poker game. :P

Or sleeping since I work at 8am on Sat... Freaking sucks.

Anyways, Wesker's answer pretty much sums it all up, except the filtering part.

rip off prices. Every graphics card has them, 16 is a fairly normal amount.

Heh, reviving an old thread! Muwhahhaa. I've got 32 ROPs on my ATI 5850.
