[Rant]: RX 5700... a frustrating experience
Scoopta commented on 12 January 2020 at 9:15 pm UTC

TuxeeHow do you get ROCm to work with a RX 5700, when statements like these are out:

https://github.com/RadeonOpenCompute/ROCm/issues/819#issuecomment-532886041

and looking it up

https://rocm.github.io/hardware.html

A working ROCm on an RX 5700 would be nothing short of a miracle.

Second point (and I think I stated this in my original post): It's not that the card doesn't work at all. It's just some heavy lifting on an 18.04 Ubuntu (which is (a) probably the most popular distro and (b) the "recommended distro for the official AMD driver). Once you get it running everything's "quite ok". BUT - and that's my biggest gripe - it is the instability of the setup:
18.04/Kernel 5.3/Mesa 20.0 - works (my current setup)
18.04/Kernel 5.4/Mesa 20.0 - nope
19.10/Kernel 5.3/Mesa 20.0 - nope
19.10/Kernel 5.4/Mesa 20.0 - works, BUT (again) SotTR gives me 22fps vs. the 100 in the working 18.04 setup
AND you have to be cautious about "other things installed" - the working 19.10 setup crashed with lm-sensors/sensors installed. (At this point I might start to mix up some of the working/not-working configurations, but several days of tinkering are hands-down a PITA.)
OTOH: Ubuntu has a graphics drivers PPA which provide the most recent NVidia drivers pretty much immediately after release:

https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa?field.series_filter=bionic

Now that's something I consider simple...
Well I failed to live by my own moto on that one. I did no research about ROCm and don't actually use OpenCL other than the one time I wanted to test ROCm, I honestly just assumed it worked without looking into it. So yes, you're right, you need the proprietary runtime which sucks. Also I can't speak to ubuntu but at least for me that's been my experience. On my distro the only thing that was missing when I bought my card was the firmware, kernel was already in the repos, same with mesa. All I did was unpack the firmware from kernel.org and everything worked great but again that's probably cause I'm on a rolling release. For me it was simple, also I have lm-sensors and it works correctly, giving me all my temps for my card just fine so not sure what would cause that. Also looking at the recommended distro for the proprietary drivers is irrelevant when using mesa however you're probably right in calling it the most popular. I'm surprised ubuntu has this many issues with it. Then again the entire reason I moved to rolling release was because I had issues playing games on stable many many years ago. I think I had an HD 7870 at the time. Honestly I don't know why you've had a poor experience but I can certainly say I didn't. The unfortunate thing about this...with the exception of OpenCL, is this isn't even AMDs issue. That is to say it's an issue with the Linux ecosystem as a whole considering you can have 2 people with the same hardware on different distros with such wildly different results. I might try ubuntu in a container or dual boot.

With lm-sensors I got flooded with AMDGPU: [poweplay] ... messages. Right now I think I'm gonna leave it there and once 5.5 is out I'll switch to the in-development 20.04 Ubuntu and see how that works out.

Alright, hopefully things smooth out. I hate to see people having bad experiences with FOSS and that's ultimately the biggest difference between nvidia and AMD.

For me it was as simple as switching to Kisak's Mesa PPA (was using Padoka's PPA with my previous Polaris card), and everything just worked. I'm sorry you've had a difficult time, but you shouldn't assume everyone else will.


BTW: Having lm-sensors installed or running sensors in the terminal does not cause powerplay errors for me on Mint 19 / Linux 5.4.10 / Mesa 19.3.2. I thought the problem was with some desktop hardware monitor applications?

Tuxee commented on 12 January 2020 at 10:25 pm UTC

Hm. I could give the Kisak PPA a try with my 19.10 on the secondary drive... lm-sensors on my 18.04 doesn't do any harm either. Maybe it wasn't lm-sensors at all but some completely different. That's what I meant above with the "instabilty".

For those owning a Sapphire Pulse Radeon RX 5700 card, does it have zero fan function?
If so, does it work out of the box with the amdgpu driver?

Prices for the RX 5700 are dropping at the moment, which makes it tempting to get one.

Cheers for that info. Had my eyes on the Nitro card, and it hasn't decreased in price (probably a little up tbh), but I see the 'normal' Sapphire XT is down a little bit.

Still concerned about the driver issues, though, since I'm not on a bleeding edge stuff. From what I can tell (I'm on Mint 19.2 still), I don't have access to 5.5 yet (nor 5.4), so would have to rely on the 5.3 kernel.

Keep hoping for an actual sale, but doesn't look like any stores here are interested in that.


As an aside, when are the new Nvidia cards out? Maybe that will push the AMD price down a bit more?

My experience so far with the 5700 XT.

Not a single problem on stock Arch and Windows 10.
Performance is stellar (okay, I'm coming from a HD 7950).
I can drive anything in 1440p with maximum details so far and still have high stable framerates.

Using still my 11 years old be-quite 550 W power supply (paired with a Ryzen 7 3700X).

Yeah, the prices haven't come down by a wide margin. The cards still cost more than 300 EUR/USD where I live. But the aforementioned Sapphire card has come down by 10 to 20 EUR and the MSI Radeon RX 5700 MECH GP OC currently costs only a little more than 300 EUR, which is why I'm looking a little closer now at these cards again.

Unfortunately, my preferred model, the PowerColor Radeon RX 5700 Red Dragon, has become more expensive at the same time.

Don't know what's up next at camp nVidia. But apparently nVidia has dropped the price for their RTX 2060 card to bring it closer to AMD's new 5600 cards and maybe that will have an effect on the current AMD lineup as well.

sub[...] Using still my 11 years old be-quite 550 W power supply (paired with a Ryzen 7 3700X).

Thanks for the info, that's good to read. It's exactly the same setup that I'm currently running.

Anyway, I'm not really in need of a new GPU and frankly, getting one would only mean burning money. My RX 570 still gets all the things done that I throw at it (at high or ultra settings at full HD). But as I said, the RX 5700 is tempting at the current price level.

Yes, and it does work out of the box. My GPU fans are not spinning right now. I've got the XT, but I think it works the same on the non-XT.
