Blender 2.82a Mac OS with Pro Render 2.3 and eGPU
If this is the card:AMD Radeon RX 6800 XT
That's within my reach.
Not available of course.. but I'll wait.
Problem is I don't see it on the list of cards that work in the Razer Core X.
just chatted with a guy from AMD, next Thursday they’ll be some available. First come first serve. Fingers crossed I guess.
@madcat235, Well… yeah. AMD is sketch AF.
No one can get chips right now. Supposedly this will change within another 6-months.
if this https://www.amazon.com/gp/aw/d/B08Q7KF1FR/ref=sspa_mw_detail_0?ie=UTF8&psc=1&pd_rd_i=B08Q7KF1FRp13NParams works with the new AMD 6800xt I’m ok with that.
Biggest problem I have is sorting through which card is which on a chart. There’s a lot that have “6800” in the name.
Confuses me so much my brain hurts…
any opinion on the AMD Pro cards? That’s my other option.
Big Sur should have good driver support for the Pro W5500 card, as my consumer RX 5500 XT version is 100% stable and reliable.
Updating this thread.
Hey, here's the current (as of Sep 2021) versions of Blender for Intel Macs and AMD's Radeon Pro Render plug-in for GPU rendering:
Blender 2.93 LTS
Radeon ProRender 3.2
You can keep in mind a couple of basic installation steps:
1. Save the ProRender plug-in download (hosted on GitHub) to your Intel Mac as a .zip file. (You don't need to open the .zip file)
2. You can install Blender and AMD's "ProRender Material Library" from their familiar Mac format .dmg disk images.
(Remember to open and unlock the Security and Privacy panel in MacOS System Preferences in order to approve the installation of these apps on your Mac)
When you have Blender up and running, you can click on "Edit" + "Preferences" to then "Install" the RadeonProRenderforBlender3.2.3MacOS.zip file in Blender's "Add-ons" panel.
(And then whenever you open a new Blender model file, make sure the "Render: Radeon ProRender" Add-on box remains checked)
Okay. So to quickly evaluate ProRender's current capabilities (as AMD maintains ongoing development) load up one of the Blender-hosted demo files, and select "Radeon ProRender" as your render engine.
It's pretty clear that amongst the demo files available on the site ( Demo Files — blender.org ) the capabilities of Radeon ProRender 3.2's materials and shaders are best shown by rendering the Italian Flat model.
I def recommend the Italian Flat over the ubiquitous BMW and Classroom models. The materials and shaders used in Italian Flat are a much better match for Radeon ProRender. The resulting image is a big level-up over BMW and Classroom.
Italian Flat (artist: Flavio Della Tommasa) rendering time with denoising: 2 mins 55 seconds.
(AMD Radeon Pro W5500 8GB in eGPU connected over TB3. MacOS Metal graphics API)
Overall, with the right model, materials, and shaders, ProRender can produce a good mix of speed and image quality.
As with all renderers, Denoising and Clamping tools are essential to achieving both - and, happily, ProRender's current versions produce good results.
And, hey - if you're interested in some additional raw data, look for a few Blender GPU rendering speed benchmarks (using ProRender and Cycles) I'll be adding to another post:
@itsage, Cool - here are the complete settings I am using to render the Italian Flat demo file on my W5500.
Render tab settings
Layer tab settings
These are good settings for sample quantity, light ray depth, and (GPU) tile rendering size, and incorporate use of denoising and clamping tools (to eliminate "fireflies").
(These settings make sense for Italian Flat specifically. For other models I adjust the sample quantity to a greater or lesser number until I find a practical mix of speed and image quality)
BTW - you can disregard the initial render time of any Blender model. You’ll notice the first pass includes extra time for building and compiling render kernels.
Subsequent renders happen more quickly.
