Graphic card: GTX 960 or R9 280 ?
« on: February 17, 2015, 09:03:40 PM »
Hello, what would be recommended graphics card for photoscan? Nvidia GTX 960 2 GB or ATI R9 280 3GB (or even R9 280X)? Or even some other card in this price range? Dont recommend please anything more expensive, i dont have the money, cpu will be core i7 4790K probably.

I have read here that nvidia cards are not good with photoscan, even the new one?

GTX780 if your price range is around $200-250 and you dont mind used cards. I just picked up 4 for $800 just last month.

Thanks for reply, i will look into that, but if i dont want a used card? which one from those 2 would you recomend me?

also is is still true (new drivers might changed something or ne version of agisoft as well), that ati cards in the same price range are generally faster (a LOT faste) in agisoft, then nvidia cards?

Hello JohnyJoe,

According to the specification info, GTX 960 would be about 2 times slower than GTX 980, and R9 280X about 1,5 times slower than R9 290X.
For the cards that are mentioned as a reference you can find quite a low of performance output info in the benchmark thread.

Thanks for reply, and is it true, that otherwise similiar cards (performance wise in GAMES) will have huge difference in photoscan, because ATI has better opencl implementation, and even if some ATI graphics card has lets say performance of 80 fps , and some NVIDIA card has the same performace in the game 80 fps, the ATI CARD will be much faster in photoscan than the nvidia one?

ATI cards have much much better Open CL drivers and optimizations compared to Nvidia which chooses to focus its time and energy on CUDA processing.

Thanks, is it a question of purely drivers, or is the also the architecture of the cards...? what im asking is if there is a chance and a possibility that Nvidia will improve greatly their drivers (software) and with this boost their performance in opencl? Is it even possible, or do the ati cards have simply better hardware architecture for open cl?
