Blender 2.79 includes new AMD OpenCL optimizations and Faster AMD OpenCL rendering and feature parity with NVidia CUDA.

Hello,

For anyone interested in 3D Graphics and Rendering, there looks to be some good news on the way when Blender 2.79 gets released for owners of AMD Graphics Cards.

Two key features will help improve rendering times and productivity.
Blender 2.79 includes:

1. New AMD OpenCL optimizations
2. Faster AMD OpenCL rendering and feature parity with NVidia CUDA.


I am seeing significant performance improvements in Blender 2.79 Release Candidate 2 so far running on a range of testcases, both blender benchmarks and my own testcases.
I was unable to run Dual R9 Nano GPU's in Blender version 2.78c. This works for my cards in Version 2.9 Release Candidate 2.
I am seeing performance improvements over and above just the fact that I can run renders with two GPU's instead of one.
I understand this is not a production version of Blender but you might want to download it and take a look.

You can get information on the Blender 2.79 Release Candidate 2 code here:
Dev:Ref/Release Notes/2.79 - BlenderWiki


If anyone does decide to test the Blender 2.79 Release Candidate 2 and is lucky enough to have an RX Vega 64 I would be grateful if you would give it a try, and also give some feedback on use of High Bandwidth Cache Controller for large rendering jobs where the native GPU Memory Capacity (in my case 4GB, but in Vega Case 8GB or 16GB) is a problem. 

Cheers.

Blender Foundation has just released version 2.79 is anyone is interested to give it a try.

I have been working on and testing the 2.79 RC2 code.

If the main release works as well as the RC2 version the AMD Card owners should see significant improvement.

I am testing that now.

If anyone else has any feedback on Blender 2.79 I would be more than interested to hear your feedback.
Thank you.

Hi! I was able to get OpenCL to at least show in the preferences by starting Blender with the flag '--debug-value 256', going to the Render panel -> debug and OpenCL Flags: split.

However, when I try to render I get this:

I'd be grateful for any suggestions to try.

Any update w.r.t. AMD RX5700XT/6800XT performance improvements for latest version of Blender? 

 

Thanks.
