Radeon ROCm 2.0 OpenCL Benchmarks With Linux 5.0 On Ubuntu 18.10 vs. NVIDIA's Linux Driver

One of the areas where ROCm still can be improved upon is lowering the kernel latency compared to the NVIDIA Linux driver stack.

It will certainly be interesting to see where Radeon VII fits into this equation for open-source Linux GPU compute performance compared to NVIDIA's proprietary OpenCL driver performance.

Over the many different OpenCL benchmarks carried out in this latest comparison, here is the geometric mean looking at all of the OpenCL benchmarks across the tested GPUs:

In this case, the Radeon RX Vega 64 with ROCm 2.0 is coming in just below the GeForce GTX 1080 while the Radeon RX Vega 56 is aligned with the GeForce GTX 1070 and the Radeon RX 590 hitting the GTX 1060. It's not as ideal performance as their more mature OpenGL and Vulkan graphics driver offerings, but it will certainly be interesting to see what the Radeon Open Compute (ROCm) stack has in store for 2019. Back during CES 2019, AMD talked of Radeon VII delivering a ~60%+ performance jump in GPU compute workloads so it will also be interesting to see shortly if that pans out as well for ROCm 2.0 or will require additional software optimizations.

If you missed it from yesterday are the fresh OpenGL/Vulkan Linux gaming benchmarks as well using the latest Linux driver components from each vendor.
