Windows software using Vulkan directly works equally fine with RADV and AMDVLK with the TessMark MSI Kombustor tests being a notable exception. We have verified that the resulting images are identical, none of the Vulkan drivers cheat in any way (unlike what we see in the LuxMark OpenCL benchmark with Mesa Clover prior to Mesa 21 and AMD ROCm, the image Clover from Mesa <=20.3.x produces isn't correct or valid). These are not theoretical workloads, these benchmarks measure how long it takes to up-scale real images using Vulkan compute. waifu2x will always up-scale 2x, RealSR will always up-scale 4x. waifu2x is most suitable for anime pictures, RealSR is suitable for all kinds of pictures. Waifu2x and RealSR are both popular image up-scaling programs. Compute really is a very different story. Which driver you use doesn't matter all that much in graphical applications, they both perform similarly. There is, as you will see from the numbers, a huge difference. Vulkan Compute is an area where AMDVLK is noticeably slower than the Mesa RADV Vulkan driver.
RADV wins the vkmark benchmark by a margin that is so small it is barely measurable. It is, luckily, quite easy to have both drivers installed and choose what game or application uses what driver. Both AMDVLK and RADV work fine with most games, but there are some that work better with AMDVLK or vice versa. Which you should use is therefore mostly a question of what driver works best with the game(s) you would like to play. It has to be acquired and installed separately.īoth drivers will mostly provide the same performance with Vulkan compute as a notable exception. There is another alternative, a special Vulkan driver from AMD called AMDVLK. The Asahi scene demo rendered in Wine with RADV.Īll the GNU/Linux distributions come with the Mesa RADV Vulkan driver for AMD graphics cards as part of the standard Mesa graphics stack. Written by 윤채경 (Yoon Chae-kyung) - last edited. Here is a test of the latest AMDVLK 2021.Q2.1 driver against the latest Mesa 21.0.3 RADV driver in some graphical and compute applications. There are two Vulkan drivers for AMD graphics cards available: The RADV driver that comes with Mesa and the AMDVLK driver from AMD.
