AMD Radeon RX 6400 - a good choice for TW?

English Install/Boot/Login
#1

Hi!

Experiencing some electronic dementia issues with my NVIDIA NVS 310 in TW/KDE

and though about trying an AMD GPU to see if things improve (as some 10 TW installs don’t have such issues).

Use case is NO gaming, some browser, streaming via VLC and TV via kaffeine, not more. Hardware is a Dell Precision T5810.

Is the Radeon RX 6400 a good choice (at least the price is within reach…) for use with TW?

Many thanks in advance for suggestions

Have a “RX-560 4GB” on a desktop and works just fine.
it’s displaying at 3840 x 1600 (38" monitor) just fine.
Yea, it’s not a laptop, but still …
You could google: “rx-6400 vs rx-560” … the 6400 is preferred.

Simply install the “kernel-firmware-amdgpu” and “xf86-video-amdgpu” and “libdrm_amdgpu1” packages.

  • If you’re using an AMD CPU then, also install the “ucode-amd” package.

Everything else is included with the openSUSE Kernel package.

  • You shouldn’t need to blacklist the Radeon firmware and drivers – that’s automagically handled these days …

Ok, so no quirks to be expected? Not too new, not too old, should work with the kernel-firmware and xf86 packages ootb and run smooth and stable? :slight_smile:

@suse_rasputin:

The documentation for the driver back-porting done for the SLE and openSUSE Kernels is located in the Kernel patch information.
In general, all the GPUs supported by the newest Linux Kernel are mostly supported also by the SLE and openSUSE Kernels.

A possible place to check for support of a specific AMD GPU is the X.Org Radeon Feature: <https://www.x.org/wiki/RadeonFeature/>.

I’m more interested in satisfied user feedback, tbh :wink:

I had some very specific feedback for NVIDIA cards in the past on the forum here and before spending some money I want a definite “go” for the card or other suggestions from users :slight_smile:

#7

@suse_rasputin research RDNA vs GCN on linux? What is you current slot (PCIe version and width) that your popping the card into? Will that M/B slot provide the power for the card?

#8

Hi Malcolm!

I have here PCIe3 x 16, but I’m not looking for a graphics monster, just as described above

Power + extra comes from the board, but the power supply can for sure provide some extra power, but really needed for my use case? :wink:

#9

@suse_rasputin then I would look at a RX5xx series PCIe 3.0 x16 The RX 6400 4GB DDR6 is PCIe 4.0 x4 @ 53W, you existing card is PCIe 2.0 x16 @ 19.5W.

I’ve got a RX550 (Polaris series, slot powered) that I did use, now swapped back to a Quadro T400 (2GB and PCIe 3.0 x16 @ 30W), I have a HP laptop here with dual amd gpus running MicroOS Aeon fine.

You can fit a full size card or does it need to be half height?

full is possible… lalalalaaa… (min 20 char…)

#11

@suse_rasputin then look at the RX5xx series to get full bang for your buck :wink: The RX550 worked fine, the model I got has four (4) HDMI outputs and was slot powered.

…never heared of something like “shinobee”… is it China trash?

@suse_rasputin I got a ‘Docooler Yeston RX550-4G 4HDMI 4-Screen Graphics Card Support Split Screen 10bit Color Depth HDR 4G/128bit/GDDR5 with 4 HDMI Ports’ from China, that was back in the beginning of 2021…

Hi Malcom, sounds good so far. :slight_smile: What was the reason for switching back to the dark side of graphics (NVIDIA)? :wink:

#15

@suse_rasputin more cuda cores plus encoders/decoders… and the T400 was a great price, then added a Tesla P4 to the mix.

#16

@malcolm, additional question: how do you use the Quadro T400? with nouveau? NVIDIA driver?

#17

@suse_rasputin I use the nvida proprietary drivers installed the hard way.

#18

Are there any advantages? You have to install newly after EACH new kernel, correct?

#19

@suse_rasputin yes I boot to multi-user.target run the installer and reboot a few minutes and all done.

#21

But the “new” driver has to be available for each new kernel, right? Would the card work without the NVIDIA driver with TW ootb…?
