7990 and OpenCL

post #1 of 6
Thread Starter 
It's considered like two different cards for that purpose right? Because I discount the card on the basis some applications I use are single-core OpenCL so it would be half useless on them.

7990 is two 7970 jammed together on one board and treated as such by OpenCL.

Yep it is treated as two GPU's essentially. Out of curisosity what OpenCL application are you running that will only utilize a single GPU? Many applications are now switching to using two or more GPUs at the same time but crossfire has to be disabled and bridges removed for it to work.

Video post processing on the fly. I realize I'm exaggerating since even a GTX 660 does most of the required work, but it would get to my nerves that video playback is 50% of what I'm doing and half of the card would be useless, plus I could use the quietest card possible, since doing little work would also keep it quite.

madVR is heavy in itself on the most complex algorithms, and I couple it with SVP, which is another GPU hog.

Hmm...I haven't looked at MadVR myself in quite sometime (2+ years) so I couldn't tell you that much but I'm fairly certain that wouldn't benefit from a dual GPU card (I say that because it is real-time video processing). You may see a boost from switching that to an AMD card if you have one though. OpenCL applications like that are generally handled better on them.

I really suggest madVR to everyone. Once you see the advantage you'll never go back.

I even couple it with SVP for pseudo-60FPS. In fact, it's my favorite feature of the two.
