Radeon RADV "ACO" Performance On Mesa 19.3 Looking Good

With the ACO shader compiler back-end merged for Mesa 19.3 as of mid-September and more improvements merged since then, it's now very easy to try out this alternative to AMD's longstanding AMDGPU LLVM compiler back-end. ACO, which is developed by Valve and their contractors outside of AMD, is looking quite good not only for quicker shader compilation (more punctual game load times) but also helping the performance of some Vulkan-powered games. Here are our latest ACO benchmarks.

Older Broadwell Graphics Performance Is Looking Good With The New Intel Gallium3D OpenGL Linux Driver

A majority of our benchmarking of Intel's new Gallium3D OpenGL open-source driver is done with various "Gen9" graphics hardware given its proliferation and not yet having any Icelake Gen11 graphics hardware for Linux benchmarking. But with the Iris Gallium3D going back to supporting Broadwell "Gen8" graphics, here is a fresh look at how that oldest supported Intel hardware is working for this new Linux open-source OpenGL driver compared to the current default "i965" Intel OpenGL driver too.

Intel's Gallium3D Driver Is Running Much Faster Than Their Current OpenGL Linux Driver With Mesa 19.3

Last month I did some fresh benchmarks of Intel's new open-source OpenGL Linux driver with Mesa 19.2 and those results were looking good as tested with a Core i9 9900K. Since then, more Intel Gallium3D driver improvements have landed for what will become Mesa 19.3 next quarter. In taking another look at their former/current and new OpenGL drivers, here are fresh benchmarks of the latest code using a Core i7 8700K desktop as well as a Core i7 8550U Dell XPS laptop.

Intel's New OpenGL Driver Is Looking Really Great With The Upcoming Mesa 19.2

Intel's new open-source OpenGL Linux driver "Iris" Gallium3D that has been in development for the past two years or so is getting ready to enter the limelight. Months ago they talked of plans to have it ready to become their default OpenGL driver by the end of the calendar year and with the state of Mesa 19.2 it's looking like that goal can be realized in time. With our new tests of this driver, in most games and other graphics applications the performance of this Gallium3D driver is now beyond that of their "classic" i965 Mesa driver.

Benchmarking Valve's RADV+ACO Yields Fastest Open-Source Radeon Vulkan Driver

Last week Valve formally announced their new Radeon shader compiler for AMD's open-source Linux graphics drivers. At this stage it's an out-of-tree solution providing generally faster performance to the Mesa RADV Vulkan driver over the current AMDGPU LLVM shader compiler but they also have ambitions of wiring it up to the RadeonSI OpenGL driver once mature too, assuming AMD's developers are willing to make use of this new compiler code. For those wondering about the Vulkan performance, here are our independent benchmarks of the current Mesa 19.2 RADV performance with the LLVM shader compiler compared to Valve's new "ACO" compiler back-end and then also using AMD's official AMDVLK reference driver that is also leveraging LLVM.

The Current Radeon RX Vega 64 / Radeon VII Linux OpenCL Performance Against NVIDIA

Recently I provided a fresh look at the Radeon VII Linux gaming performance (as well as comparing AMDVLK vs. RADV) now that I have a Vega 20 graphics card running great under Linux after the pre-production VII had failed. One of the other areas I was curious to see how the Linux performance evolved in the few months since the original Radeon VII Linux benchmarks was checking on the ROCm OpenCL performance. Here are those results up against NVIDIA with their proprietary Linux graphics driver.
