A8-6410 with AMD graphics, Iray renders. So, the graphics were basically driving the viewport, but didn't help with the rendering at all.
SLLLLLLOOOOOOOOOOOOOOOOOOOOOOOOOOOWWW...
(CPU only rendering).
Really, any computer that can run Daz Studio can render (well, maybe not if you have only 4 GB of ram or something), it'll just take a long time for Iray if you don't have CUDA cores. A strategy along these lines (if you have a spare computer sitting around) is to use your first computer to set up the renders, and your second computer to bake them. That way you can still use the first computer to set up your next scene, play games, etc...
I'm actually using that A8-6410 system right now to type this (my Render computer died), and am about to buy the replacement 'interim' render system. I refuse to render on this laptop again. The screen is tiny, and besides, the internal SSD is full... so I'm taking a break from rendering until the new system arrives.
But, of course, if you are doing Iray, yeah get an Nvidia CUDA card already! As for 3Delight, yeah more cores good... no one has started a 3Delight benchmark thread, at least not that I can find, but I'd imagine the Threadripper 2990WX might do OK...
