Unsupported GCN cards available to select for Cycles
Closed, ResolvedPublic

Description

Hello. I have rendering problem using GPU Compute. GPU compute is slower that CPU and it's incorrect. On the picture you can see how it's look like. Cannot render even simply models. I have AMD radeon R5 M330 2GB graphic card (CPU Intel core i5). I'm using the last version (downloaded today).

It looks like your GPU is from GCN 1 generation. Its unfortunate, but support for those cards had to be dropped. Your card shouldn't have been available to select for GPU rendering, did you enable debug mode? This mode isn't meant for regular use, and cant be expected to function properly. If you didn't enable debug mode and were still able to select your card then that would be a bug we should fix.

See AMD OpenCL sections here for more info:

https://docs.blender.org/manual/en/dev/render/cycles/gpu_rendering.html
https://wiki.blender.org/index.php/Dev:Source/Render/Cycles/OpenCL#Supported_AMD_Cards

Also please don't triage reports your self, leave that to someone else.

I'm not using debug mode but I can choose my graphic card in system setting. But as You said it's first GCN generation.

Could you please find and run the program clinfo and attach the output, it will help in figuring out why your card is listed when it shouldn't be.
