Can anyone come up with a definitive answer to which GPU renders faster a GPU with (example) 2500 CUDA cores or 2500 Stream Processors?
I can only come up with probably not definitive but only my personal answer that CUDA rendering by GPU is ancient and it was for me very faulty.
Today the newer Magix codecs render with help of decoding and encoding with GPU help especially with NVDEC resp. NVENC and it works pretty good and fast with GPU besides the CPU.
J-V, can you direct me to a specific link/location/YouTube video which describes your assessment of your answer? Thanks for chiming in on my query.
No, I have only my own proof for my experiences and how I do that by using Vegas Pro 17 rendering with Magix AVC or HEVC codecs in all sorts of MP4 export
Rendering with the NVENC option goes upto 6 times faster than the common Mainconcept codec on my desktop from signature.
These days, gpu rendering is done by dedicated hardware on the gpu that does nothing but encode. The cuda/compute cores are used for effects acceleration on the timeline. As for which is better, that's debatable.
@vegaseditor your question really relates to Nvidia vrs AMD because Nvidia calls its graphics cores Cuda processors while AMD calls its stream processors. But Nvidia and AMD architectures are so different. So Cuda and Stream processor counts do not compare 1 for 1. Also the depth of open-source support (AMD tends to be open while Nvidia tends to license). As well as Vegas versions which are optimized differently. Suggest you just go by comparing benchmarks, reviews, and/or user testimonials of the best cards you can afford.
Howard, thank you for your input. But....."yes," I was comparing based on equivalents. Your mentioning to go by what's already published still leaves me (and others) still questioning which is more efficient/faster. If you can direct me to a link in which someone has published a side-by-side of comparable Nvidia vs AMD GPU's which would show direct comparisons, then you will have done what no one, so far, has been able to post.

If none of the above satisfy you, and you can't find within these "Forum Halls of Wisdom" from all of the contributing members, then time to do your own testing.
Oh, and here is some Bench-marking results from the actual members in this forum, thanks to @JN- for keeping it "fresh & updated" :).
I would just add to the links @Chief24 posted above Bench-marking results I've obtained on my own systems which are mostly AMD.
Chief24 & Howard, thank you both for your input. This data has given me some new info to consider when deciding on what brand/version to purchase. I know these results are a little outdated, but it's still a great guide.
