Trying Out The New Intel Open-Source OpenCL NEO Compute Driver

SHOC's bus speed download test did pass with the NEO driver stack and it is reporting better performance than Beignet with this synthetic speed test.

Darktable with RAW image processing using OpenCL was reporting similar performance to Beignet, but didn't really expect much of a difference there since the OpenCL processing was already quite quick.

The Blender OpenCL performance was similar to slightly faster in some scenes with the OpenCL rendering on NEO.

Overall, the Intel NEO OpenCL driver stack holds a lot of potential though for already exhibiting OpenCL 2.1 capabilities while being cross-platform and open-source. I'll be trying this NEO driver on some other Intel boxes shortly for seeing how it works there and hopefully works around some of the OpenCL tests not running with NEO on this i7-8700K system. Hopefully Intel will also be able to work on upstreaming some of their LLVM/Clang changes and working this new compute stack into shape so it can be more easily deployed by Intel Linux users for easily making use of this modern OpenCL functionality with HD/UHD/Iris graphics hardware.
