#2This seems to be the change that adds support for HIP: https://developer.blender.org/rB044a77352f8a8a0e1f60190369d6...

#3Looks like AMD's open source strategy is starting to pay off.

I wouldn't go that far. Nvidia and even Intel have had hardware-accelerated features in Blender (RTX-acceleration and Optix, respectively), so this is more about getting them back on the same level. I do really like AMD GPUs though, I'd be interested to see how this performs on their APUs with the Vega graphics.

#5What does this mean for ProRender? AMDs Blender strategy is kinda confusing.

#6Note that this is only supported on RDNA2 onwards.
It is _enabled_ on 1st gen RDNA, but with no "official support" from AMD. (as such, no SLAs or any guarantees really)
On prior generations, it's not enabled at all. (Vega, Polaris)

#8Maybe ROCm support for Navi hardware is finally going to be released.

#9Glad to hear it. We're going on 10 years since Blender notionally got OpenCL support, I bought an AMD GPU on that basis, found out that the "OpenCL support" was so thoroughly dismal that it was slower than my CPU, sold my AMD card, ate the ebay fees, bought an NVidia card, ate the green tax, and got on with my work.
I had to repeat that lesson a few years later with deep learning code before it stuck.
Hopefully this time is different. I'm cautiously optimistic... but I'll let someone else be the guinea pig.

#10Why HIP and not for example Vulkan?
UPDATE:
Looks like this more about adapting existing CUDA code to work with AMD. So it makes sense as the least resistance approach I suppose.
