NVidia GTX580 + RX480 on the same PC. Does it work?

Hi guys,

After reading one of the older discussions (https://www.vegascreativesoftware.info/us/forum/nvidia-1080-video-card--104895/#ca648307) about combining NVidia and AMD card on the same PC I'm tempted to try it.

I run Vegas Pro 14 on W10, i7-6800K, 32GB of RAM, old EVGA GTX580, PS EVGA 1000W. No plans to upgrade to 15 or 16.

The good old GTX580 CUDA works great for my MainConcept AVC mp4 rendering for internet but it's not good enough for smooth timeline with videos modified with heavy effects (color correction...). I know, this is nothing new for you. I found in this forum that smooth preview / timeline in Vegas 14 can be achieved with RX 480. Seems to be the most recommended card for Vegas Pro 14.

Q: Is it possible to combine GTX580 and RX480 (8GB) on the same PC without problems? Do you think that I could really benefit from the both worlds? Did anyone try this already? Do you foresee any conflict with drivers (please recommend the versions)?

I'd really appreciate your opinion before I buy RX480?

BTW if anyone knows where to buy a used RX480 please share it here. The new one is impossible to find. The miners got them all. I found some used on EBay, Kijiji and few on Amazon.

Hi guys,

Now I'm going to answer my own question in case someone else is interested in. Yes, it is possible to have both cards installed on the same PC. MSI RX480 8GB (Gaming X) is my main card with 2 monitors connected and old GTX580 is the 2nd one with one HDMI output to TV. I really didn't have time to play with different driver versions and their different combinations. GTX580 works at the moment with NVIDIA driver 388.13, RX480 Radeon driver version is 17.1.1.

At all the time I've used in Vegas default value for Dymanic RAM Preview=200MB.

Results:

I can use GTX580 with MainConcept AVC for mp4 rendering with one stupid condition: GTX580 can't be selected to be at the same time my GPU acceleration card (the rendering would freeze). Otherwise, with RX480 selected or no GPU acceleration at all I was able to render HD 59.94p video. In both cases: 1min of footage (no special effects applied) in 28sec which is fine by me.

I use now RX480 for a GPU acceleration with better timeline preview. Though some older projects I've tried to load with 480 crashed probably due to some special effect (very same project would work if GTX580 was selected for GPU acceleration). Go figure, I didn't have time to investigate that.

This is it for now. I'll try to install Vegas Pro 16 trial to see how this setup works with some newer rendering codecs.

I did the same two years back when I had my current AMD Fury X and a GTX580 in the system. Like you, I used the Fury X for timeline acceleration and the GTX580 for rendering MC AVC with CUDA. That combination was faster then any of the single GTX1080 setups and NVENC rending. Since VCE is now available in VP15, I just use my Fury X and save power.

Thanks for the comment OldSmoke. I'm still hesitating to upgrade to Vegas 16 since people are still finding many flaws. That's why I'm still sticking to the good old 580:)
