@rkowalke, sadly it seems that the OpenCL implementation on AMD cards is not at all stable. I had issues on both Kubuntu, and Manjaro KDE on my RX580.
It would also appear that AMD is also with drawing support for some Radeon cards with the ROCm 4.0 release. So sometimes having the latest and greatest via rolling releases isn’t so good if it results in support for your graphics card being withdrawn.
I’d personally rather use closed source drivers which work, rather than opensource ones which do not.
I’ve certainly had my fingers burned with AMD Radeon GPUs. I suspect my next GPU will be something along the lines of an Nvidia GTX1660 Super or similar.
You see, that’s just one frame and it took 4:30 in 960*540px! Imagine rendering a 10s animation
I’ve done a glitch effect where I put a lens element, and emissive path behind it. It takes roughly 60s min per frame. That is too much especially on my GPU on which they advertised millions of polygons being rendered in less than 30 seconds in 8k.
Guys, OpenCL is an off-loading computing library. Just because OpenGL, aka the graphics lib used in GUI painting and games real-time rendering, works “great” doesn’t mean OpenCL is supported as well. “Drivers” mean nothing.
Do you have any experience running AMD and Nvidia gpu on the same system at the same time?
I wonder if that could work ok because I’d like to move to Nvidia but I don’t want to have an 800eur AMD gpu sitting on a shelf.
It’s like when I started with 3d studio 4 “some years ago” in my 486SX (SX = no i487 math coprocessor). Years later I had a pentium with coprocessor, what a difference!
I know the difference between OpenGL and OpenCL. Also most of the time I find users complaining about older generation cards like RX 580, and that people got frustrated here is conprehensible.
Probably best to buy a new GPU first though, as there doesn’t seem to be much available at the moment. There are a few “pictures” of high end GPUs for sale on Ebay though! I wonder if anyone will be silly enough to bid on them?
A spot of googling this evening, and I found a retailer which had an MSI GTX 1660 VENTUS XS 6G OC 6GB Graphics Card in stock. So all being well, it should be with me in a few days. A tad more expensive than the RX580, but should be a better card for my uses!
