Hi,
I'm using a external GPU

sonnet box
ati vega 64

on Mac OS x

Blender read the card but don't work

System Information
Operating system and graphics card

Blender Version
Broken: (example: 2.69.7 4b206af, see splash screen)
Worked: (optional)

Short description of error

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

Which macOS version and are drivers up to date? Could you also give some debug information (start blender from terminal and add --debug-gpu parameter. Which blender version do you have?

Marking as "Incomplete" until the requested information/data is provided.

On Sonnet site:

macOS High Sierra has only beta support for connection of GPU cards over Thunderbolt and GPU card drivers are not yet officially Thunderbolt compatible for macOS.

It is not clear to if you are trying to use this card for OpenGL, or for Cycles OpenCL rendering. Either way we need more info:

If this is for Cycles rendering, you could try another OpenCL software like http://www.luxmark.info/ to verify if it's a problem in Blender, or an issue with the hardware or operating system.
How does it fail exactly? Is the card not detected? Does it crash, and if so when exactly? Is there an error message, and if so what? Does it fail for all .blend files, or only a specific one that you can attach here?
As mentioned above, please run Blender from the terminal with --debug-cycles --debug-gpu and attach any output from the terminal here.

Radeon Vega10 XT ? Go to user settings, system, and check what OpenCL compute devices you have available.

Consulting all knowing internet, I'd suspect this to be driver issue.
Drivers for eGPU are coming this spring. It does already work on some degree with High Sierra but not fully.

It wouldn't surprise me if the OpenCL driver was not (yet?) optimized for this. Either way it is really difficult for us to investigate this issue without having similar hardware ourselves.

Getting a full log from a render like this could give clues, ideally using the latest build from https://builder.blender.org/download/.

./blender.app/Contents/MacOS/blender --debug-cycles -b bmw27_gpu.blend -f 1 &> bmw27.log

Hi,

I am using the Sonnet Radeon RX 570 eGFX Breakaway Puck and I get very poor performance. Very very low cycles render.

To have the idea, I have used the bmw27_gpu.blend file and get this renders time:

...

I found on the log some problems:

I don't know if I install the Windows 10 on Bootcamp if it will work.... don't know if this is an OSX driver issue or blender issue.

Im using an 8 core iMac Pro with Vega 56 and latest version of Blender.

Cycles GPU rendering is totally unusable. BMW benchmark takes almost 2 hours to complete. However, using AMD ProRender engine, Blender GPU rendering is very fast.

Also, running Blender from Bootcamp gets ~6 minute BMW GPU benchmark Cycles render times. So it appears to be an issue between Cycles and MacOS.

Same issue here with a Vega 64 + Razer Core X on macOS Mojave.

One observation: I found that turning on progressive rendering partially mitigates the poor performance, bringing gpu render time for the bmw scene from 45 min down to 7 min. Unfortunately this is still slower than just using the CPU.

Only other note is that LuxMark which is also OpenCL seems to perform well on the same hardware and OS.

That is weird, I Just tried progressive rendering and it has the same effect on my Mac too— about 7 minutes to complete. Not sure why that would make such a big difference , but you’re right— still slower than CPU only.

Cycles: OpenCL on macOS has been disabled

There was a growing payload of bugs in Cycles related on OpenCL on macOS
platform, and those issues were caused by a compiler bug, which we have no
control over.

Surely, it is sometimes possible to work compiler bugs around from a
source, but we are facing some of the issues which are not solvable in this
way. Also, such solutions are usually short-living,. since adding more
features are often kicking compiler to provide buggy binary again.

In this case compiler will not get fixed since Apple decided to discontinue
OpenCL on its platform.

So the decision was made to drop support of OpenCL, keep official features
of Blender stable and predictable, and focus on things we have control over.

P.S. Older Blender releases are always available. Surely, this sounds like
using an ancient software without neat features. But we can't push Cycles
OpenCL on macOS measurably beyond that anyway.
