Here are the ups and downs of overclocking the Radeon graphics card under Linux. I'd probably go for the low quality preset as it boosted performance by about 30 at each resolution, allowing for 79.
"Yesterday I posted the initial Radeon RX 580 Linux benchmarks while now with having more time with this "Polaris Evolved" card I've been able to try out a bit more, like the AMDGPU Linux overclocking support. The RX 580 was good for 62 fps on average at 1080p and 44 fps at 1440p. Check out the steps they tried along with the results from the overlocked GPU here. They managed to increase the core by 6% without running into stability issues however when they overclocked the memory, they saw serious performance decreases. They also had a chance to try overclocking the new card, AMD added support for overclocking GCN 1.2 and newer cards on their proprietary Linux driver in 2016. The performance deltas are as you would expect, a slight increase in performance that is relative to the increased clock speeds, just as when run on Windows. Phoronix have had a chance to test out the refreshed Polaris RX 580 on the Linux 4.11 kernel and Mesa 17.1-devel, initially the AMDGPU-PRO 17. A proper RTX 2080/ 2080 Ti competitor can only be expected with Navi 21, which is likely to be at least a year away.Phoronix have had a chance to test out the refreshed Polaris RX 580 on the Linux 4.11 kernel and Mesa 17.1-devel, initially the AMDGPU-PRO 17.10 driver update was not included thanks to interesting timing. Therefore, we can expect to see OpenGL benchmarks on Linux for the Radeon RX 57 XT on launch day while compute and Vulkan results might take some time to be available.įrom what we gather so far, Navi 14 is being targeted at the lower end of the GPU spectrum to compete with the likes of the NVIDIA GeForce GTX 1650 with Navi 12 expected to take on the GTX 1660. However, Vulkan support via RADV is yet to arrive for Navi as AMD apparently hasn't seeded Navi hardware to RADV devs. Navi 10 driver code will be a part of Linux kernel 5.3 and AMD is looking to incorporate Navi 14 support as well into this kernel. Code for Navi 10 has also been posted and merged into the Mesa graphics library version 19.2, which should be part of upcoming distros such as Ubuntu 19.10 and Fedora 31.
The AMDGPU bits have been posted while the Mesa updates are still pending. Phoronix reports that the Navi 14 patch has about 1,400 lines of code. We've been hearing about Navi 12, Navi 14, and Navi 21 along with their Lite variants for quite some time and now, AMD seems to have posted Linux kernel driver patches for Navi 14 and Mesa updates for Navi 10. While RDNA-based Navi 10 GPUs such as the Radeon RX 57 XT are all set for an official launch on July 7, we do know that more Navi GPUs are in the offing suited for different price tiers. 1: open /etc/default/grub with a text editor: sudo nano /etc/default/grub, or use vim/gedit/etc.
