#INTEL OPENCL DRIVER PERFORMANCE DRIVERS#
The former Intel open-source OpenCL 'Beignet' driver remains available too, for which we took it for a fun round of benchmarking comparison for seeing how these Intel OpenCL Linux drivers currently compete to just running on the CPU via POCL. AMD does have an advantage when it comes to raw GPU power, but Intel has been working on improving their OpenCL implementation and the HD 4000 can use the i7-3770k’s eight megabyte 元 cache to improve its performance.

NVIDIA's proprietary Linux driver also only exposes OpenCL 1.2 with some 2.0 extensions. With the recent release of Ubuntu 19.04, the new Intel OpenCL NEO compute stack is available in the archive as 'intel-opencl-icd' for easy installation. Intel’s HD 4000 has 16 EUs and AMD’s HD 7660D has 384 VLIW4 cores arranged into six groups. It's fairly straight-forward to build for anyone experienced with CMake, etc, but certainly not trivial for any new-comers and there isn't yet any third-party package repositories I have found for anyone that wants to be able to easily deploy the driver at this time without having to build the patched version of LLVM/Clang and the various other components making up this OpenCL compiler.Īfter building the Neo stack, sure enough, OpenCL 2.1 support was exposed! Beautiful to see from an open-source driver stack considering Beignet was at OpenCL 1.2, AMD's ROCm is at 1.2~2.0, Gallium3D Clover is at OpenCL 1.1, etc. non-Intel specific OpenCL implementations are welcome to OneDNN oneDNN welcomes all contributions as long as they follow contribution guidelines. The basic build instructions can be found on GitHub.

I built the latest Git code for running some initial NEO tests on Ubuntu 16.04 Linux. This new Intel stack focuses on Broadwell "Gen 8" graphics hardware support and newer.īeignet had a nice run and accomplished a lot for open-source OpenCL on Intel hardware, but has now been succeeded by NEO. This NEO driver is also cross-platform, introduces a new "GMMLIB" graphics memory management library, and makes use of a new LLVM-based graphics compiler stack. While Beignet hit OpenCL 2.0 support a few months ago, NEO already exposes OpenCL 2.1 and they are on the way with OpenCL 2.2 support. This new Intel OpenCL open-source driver dubbed "NEO" that replaces the Beignet previous open-source OpenCL Linux driver as well as Intel's previous closed-source OpenCL SDK driver is in much better standing. I finally found some time to give this new open-source Intel OpenCL Linux driver a try. Last month Intel open-sourced a new "NEO" OpenCL driver including an LLVM graphics compiler and its compute runtime supporting OpenCL 2.1.
