Fresh AMDGPU-PRO vs. NVIDIA OpenCL LInux Benchmarks - 11 GPUs
Just for kicks and some extra benchmarks to look at over the weekend, here are some fresh benchmarks of 11 different GPUs when using the latest NVIDIA (370.28) and AMDGPU-PRO (16.30.3) Linux drivers on Ubuntu 16.04 LTS. The open-source (Clover-based stack) wasn't used for any open-source AMD OpenCL testing due to its less than stellar state.
Tested with the AMDGPU-PRO stack were the RX 460, RX 480, and R9 Fury. On the NVIDIA side was the GTX 780 Ti, GTX 950, GTX 960, GTX 970, GTX 980 Ti, GTX 1060, GTX 1070, and GTX 1080.
All the benchmarking, of course, was driven in a fully-automated and reproducible manner using the open-source Phoronix Test Suite benchmarking software.
Some results show clear problems in the AMDGPU-PRO driver stack.
While for other CL workloads, the AMD performance is as expected or even better.
There are a lot of data points in this OpenBenchmarking.org result file.
The only OpenCL test cases where AMD came out far ahead was in LuxMark, which tends to favor AMD hardware/drivers.
See all of the test results via this OpenBenchmarking.org result file. Or see how your own system's OpenCL compute performance compares by installing the Phoronix Test Suite and running phoronix-test-suite benchmark 1610096-LO-OPENCLOCT49.
