Phoronix: AMDVLK vs. RADV Radeon Vulkan Driver Performance For Linux Gaming On Ubuntu 19.04

With the continuously evolving RADV Mesa Radeon Vulkan driver and near-weekly updates to the AMD's official "AMDVLK" open-source tree Vulkan driver, how are these competing AMD Vulkan Linux drivers comparing these days? As it's been a while since our last benchmarking comparison of the official AMDVLK driver against the open-source and more common/popular Mesa RADV driver, here are some fresh benchmarks of RADV from Mesa 19.0 on Ubuntu 19.04 as well as 19.1-devel compared to the latest AMDVLK driver code.

Google is expected to be using RADV with Stadia

Source?

And this is a very strange test. A lot of regression compared to the old AMDVLK test.

This starts with our platform foundations of Linux and Vulkan and shows in our selection of GPUs that have open-source drivers and tools. We’re integrating LLVM and DirectX Shader Compiler to ensure you get great features and performance from our compilers and debuggers. State-of-the-art graphics tools are critical to game developers, and we’re excited to leverage and contribute to RenderDoc, GAPID and Radeon GPU Profiler — best of breed open-source graphics debugging and profiling tools that are continually improving.

Source?

I guess it's expected since Bas Nieuwenhuizen is working for Google, but no idea if there any other source.

Not looking good for amdvlk. It may occassionally win out but with RadV you just know that all your games are going to work with no bad outliers giving terrible performance. Looking at the numbers it's hard to believe that amdvlk is derived from the same codebase as the AMD windows Vulkan driver which has stellar performance.

The recently released DiRT Rally 2.0 has been running great under Steam Play / DXVK, but unfortunately not with AMDVLK. RADV has been running great for weeks but when trying AMDVLK, the game quickly hung.

The problem is I don't think Valve devs test with AMDVLK. They generally talk about and contribute only to RADV.

Hey Michael, I don't know if you or anyone cares about more steam play benchmarks, but if so then HITMAN 2 might fit the bill. Seems to work good (spent 60 hours so far) and has a built in benchmark mode.

RADV is getting better and better :-) Would have been nice to include the Radeon VII in this test round, but anyway it was interesting!

It's the same codebase, but not the same codegen backend.

dafuq just happened? amdvlk was similar or slightly faster the last time
