Benchmarking The Current Intel OpenCL NEO Driver Compute Performance On Ubuntu 19.04

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. 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.

The New Intel Gallium3D OpenGL Driver Performance Is In Great Shape For Mesa 19.1

With Mesa 19.1 now under its feature freeze, here is a look at how the new Intel "Iris" Gallium3D OpenGL driver is performing for its debut in this next quarterly Mesa feature release. Benchmarks from a Skylake NUC with Intel Iris Pro 580 graphics just wrapped up for looking at the performance of the Intel Gallium3D driver against its existing open-source "i965" Mesa OpenGL driver.

The Current Intel "Iris" Gallium3D OpenGL Performance Against i965 Mesa, Windows 10 OpenGL

It's been quite fascinating to watch the development of the Intel Iris Gallium3D driver that has now been in development by their open-source team for more than one year while back in February is where this currently experimental driver was merged into Mesa. It's been over one month since last looking at the Intel Iris Gallium3D performance relative to Intel's default "i965" Mesa OpenGL driver. Here are fresh benchmarks looking not only at their current and next-gen OpenGL Linux driver options but also how that performance compares to their current Windows 10 OpenGL driver.

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.

Intel Iris Pro 6200 Graphics - i965 vs. Iris Gallium3D OpenGL Performance

With the initial Iris Gallium3D driver that was merged into Mesa at the end of February from our tests on UHD Graphics the performance is quite promising considering the early stage of this new open-source OpenGL driver and it not yet being fully tuned/optimized. The Iris Gallium3D driver support goes back to Broadwell CPUs so I decided to run some benchmarks with the legendary Core i7 5775C that features the Iris Pro Graphics 6200 with 128MB of eDRAM.

Running The RadeonSI NIR Back-End With Mesa 19.1 Git

It's been a number of months since last trying the RadeonSI NIR back-end, which is being developed as part of the OpenGL 4.6 SPIR-V bits for this AMD OpenGL driver, but eventually RadeonSI may end up switching from TGSI to NIR by default. Given the time since we last tried it out and the increasing popularity of NIR, this weekend I did some fresh tests of the NIR back-end with a Radeon Vega graphics card.

Using G-SYNC Compatible On Linux With NVIDIA's 418.30 Beta Driver

Taking many by surprise less than one month after NVIDIA announced "G-SYNC Compatible" in supporting FreeSync/Adaptive-Sync displays as an alternative to the more expensive dedicated G-SYNC monitors, the newest Linux beta graphics driver has support for this gamer-oriented feature. This comes just a matter of days after NVIDIA began shipping their Windows driver with this dynamic refresh rate feature that aims to eliminate or at least reduce tearing and stuttering.

The AMD Radeon RX Vega Launch Performance Compared To 2019 Linux Drivers

With the AMD Radeon VII graphics card shipping in two weeks as the second-generation Vega GPU at 7nm, I figured it would be an interesting time to see how far the original Radeon RX Vega 56 and RX Vega 64 graphics card performance has evolved since their launch back in August 2017. Here is a fresh look at the current Radeon RX Vega 56/64 GPU performance today using the bleeding-edge Linux graphics drivers compared to the driver state back in 2017 for OpenGL and Vulkan gaming performance.

AMDGPU-PRO 18.50 vs. ROCm 2.0 OpenCL Performance

When recently publishing the PlaidML deep learning benchmarks and lczero chess neural network OpenCL tests, some Phoronix readers mentioned they were seeing vastly different results with using the PAL OpenCL driver in AMDGPU-PRO (Radeon Software) compared to using the ROCm compute stack. So for seeing how those two separate AMD OpenCL drivers compare, here are some benchmark results with a Vega GPU while testing ROCm 2.0 and AMDGPU-PRO 18.50.

RadeonSI Gallium3D Made Some More OpenGL Performance Gains This Year

This year the focus for modern Linux gaming really shifted to Vulkan with Feral's major new game ports being exclusively Vulkan-based, DXVK and Steam Play coming about for relying upon Vulkan for Direct3D 10/11 emulation on Linux, Vulkan 1.1 and subsequent point releases ironing out desired functionality by developers for this graphics API, and all of the open/closed-source drivers continuing to mature. But there is still a plethora of OpenGL-only Linux games out there and AMD's open-source driver team hasn't let up in continuing to improve and optimize their RadeonSI Gallium3D driver. Here are some benchmarks showing how the RadeonSI performance has improved over the past year on an AMD RX Vega graphics card.

Radeon Software 18.50 vs. Linux 4.20 + Mesa 19 Benchmarks On The AMD RX 590

While Windows users last week were greeted by the Radeon Software Adrenalin 2019 driver on the Linux side was the Radeon Software for Linux 18.50 release. The only listed public change for this 18.50 Linux hybrid driver build was RHEL 7.6 support, but I've since been able to test and confirm that the Radeon RX 590 is working with this new Linux driver package. As a result, here is a look at the Radeon RX 590 performance from this "AMDGPU-PRO" driver build compared to the latest open-source driver stack in the form of Linux 4.20 with Mesa 19.0-devel.

Radeon Vulkan Driver Benchmarks: AMDVLK 2018.4.2 vs. AMDGPU-PRO 18.40 vs. Mesa 18.2/19.0

Released this week was AMDVLK 2018.4.2 having been released this past week as the newest open-source AMD Vulkan driver code derived from their official Vulkan driver code-base but with using the AMDGPU LLVM compiler back-end over their proprietary shader compiler. For your latest Vulkan benchmark viewing pleasure is a look at this newest AMDVLK release compared to AMDGPU-PRO 18.40 (the same fundamental Vulkan driver but with the closed-source shader compiler) and then the RADV Vulkan drivers in the form of Mesa 18.2 stable and the now in-development Mesa 19.0. These four AMD Radeon Vulkan driver combinations were tested on Fiji, Polaris, and Vega graphics processors.
