RX 580 8GB significantly slower perfomance

[papajo]

My system:
CPU: AMD FX 8320
RAM: 16GB DDR3 @2400Mhz
MoBo:Asrock 970 Pro 3
GPU: Sapphire RX 580 Pulse edition 8GB
OS: Ubuntu 17.10/ kernel 4.13.0-18 generic / gnome 3.26.2 / LLVM 5.0.0
Drivers Mesa 17.3.0-rc4 - padoka PPA. (I also have olaf PPA I dont know if thats the reason... but I hade same low performance prior of adding the olaf PPA on top of padoka and after adding it either nothing has changed or I have a slight increase in performance )

My screen resolution is 1920*1080

I know that my CPU is a potential bottleneck but compared to the benchmarks I saw in this site mine are significantly lower so my gutt tells me that although there might be a bottleneck its not significan enough to be the sole reason of such big differences..

For example I see the RX 580 setup on phoronix https://www.phoronix.com/scan.php?pa...80-linux&num=1

tests tomb raider for 200++++ FPS... my benchmarks yields 60 FPS and ingame it can get as low as 10!!!

My performance in DotA 2 is like 40-60 FPS in Vulkan

7 days to die on medium settings I get 20-40 FPS

Heaven benchmark is about 40 FPS

Any ideas on what to check/ tweak?

Thanks for your help debianxfce can you help me a little more about how to use a 1000Hz timer kernel? (and why is it called 1000hz timer? ) in the links you provided in the other topic there are a bunch of kernels and non of them is characterized as a 1000hz timer but ive seen one called "amd-staging-drm-next" in some benches here... is this the one you are talking about? (I am kind of a noob but I want to learn so the more context you can provide the better )

these kernels are linked (in the other topic) as "latest AMDGPUPRO kernels" amdgpupro is the proprietary driver right? but it shares its core with MESA drivers too so the kernels linked there will work with my current mesa drivers as well right?

also why obilaf and not padoka ppas?

Oh and one lst thing there are also polaris firmware links... what is this? custom bios for the cards? should I try it? why?

Thanks again for your time and efforts.

I meant to say "how to download"

[bridgman]

Firmware is closed source driver between the open source driver and hardware. Nothing is flashed to the gpu card.

Mind if I nitpick on terminology ? Normally "driver" refers to something that runs on the CPU, while the "firmware" being discussed here is microcode running on HW state machines in the GPU and uploaded to the GPU each time the hardware is power-cycled.

[bridgman]

I'm not disagreeing with the "nothing is flashed" part of your comment, just the "driver" part.

[bridgman]

The hardware RTL offers an API to the open source driver, so hardware RTL is closed source driver too ?

If we had FPGA logic on the GPU would you consider the logic image for that to be a "closed source driver" as well ?

ok I tried to download the latest supported 4.15 kernel for ubuntu (4.15.0-041500rc1-lowlatency) after dpkg the deb files during the process I noticed this in the terminal

Should I be afraid and not reboot my system? am I ok? did it dieded? :P

[papajo]

ok after more carefully noticing the errors I see that they are about polaris 11 and 12 files (vega right? ) and raven files (apus I think) and also some errors related to virtualbox so nothing died right? I can restart my computer right? :')


EDIT: ok it did not die :P I get some pixelgarbage after grub but everything else seems to work fine.

[papajo]

Install Amd firmware:
https://packages.debian.org/stretch/...e-amd-graphics
If your can not boot to the desktop, commands for the Linux rescue mode (select it from the Grub) or the installer media Rescue mode chroot:
apt-get install wget
wget ftp.de.debian.org/debian/pool/non-free/f/firmware-nonfree/firmware-amd-graphics_20161130-3_all.deb
dpkg -i firmware-amd-graphics_20161130-3_all.deb

I get this error after dkpg:

Latest Amdgpu kernels
https://cgit.freedesktop.org/~agd5f/linux/

Use the command: git clone -b drm-next-4.15-wip git://people.freedesktop.org/~agd5f/linux
For the hdmi audio and freesync, use the amd-staging-4.12 branch. You can also use 4.15+ kernels from kernel.org, download and extract the tarball.

The kernel configuration file of Debian Official kernel are available in /boot, named after the kernel release. Copy the .config file to the linux directory. Connect all your devices and run the command: make localmodconfig. You can use the command make defconfig too for creating initial .config file.

Use the command: make xconfig and check that you have enabled: Reroute Broken IRQ, Virtualization KVM and 1000Hz CPU timer, I also disabled Swap, Kernel Debug, CPU Freq scaling , Cpu handling in Acpi, Used Bios to control CPU and devices. In the drivers->graphics->amdgpu enable cik support for a gcn 1.1 gpu and si support for a gcn 1.0 gpu.

Can you explain the bold letters in more detail?

for example what do you mean by "linux folder" ? is "/" what you mean?

make localmodconfig does nothing because it has no target

Also do I really need virtualization KVM ? I currently have it disabled in the bios (although I dont know how to make that xconfig file I am stuck at the make localmodconfig file)

Also can you desrcibe a little why those config files are needed?

Last but not least the git for the amdgpu kernels was 1GB total why is it so big? (that's what she said lol :P )
