NVIDIA Announces The GeForce GTX 1060, Linux Tests Happening

[efikkan]

I guess because availbility and prices, RX 480 sells like hot cakes there

It sold just as well as GTX 1080 did.
Which is even more impressive for GTX 1080 considering it's relatively small market share compared to ~$250 GPUs.

To quote Jean-Claude Juncker, "Why are you still here ?". This is about Nvidia.

Sorry, perhaps I misread Kano's comment. It appeared to be talking about AMD drivers. Are you saying his comment was really about NVidia drivers ?

[fuzz]

And with your Mesa example: it won't work out of the box until a new mesa/kernel is officially released, not sure if kernel 4.7 is enough and a distro ships it (for AMD you need new LLVM too which is a bit problematic for backports). Maybe next year AMDGPU can be used for GCN 1.0 parts too then AMDGPU-PRO drivers can be used for those too if needed. If you are no gamer why would you buy a 200+ $/€ card? If you are why should you pay more for a less compatible/slower card? Do you think game devs switch over to AMD soon as first target? Don't forget you could certainly get cheaper used GTX 9xx cards too for upgrades.

I use Gentoo. I've run bleeding edge kernel/libdrm/llvm/mesa for a long time. Just got done playing "Middle-Earth: Shadow of Mordor" on open source AMDGPU and my 390X on a 4k display (though I played it at 1440p).

I'm paying for good cards that support open source. If your morals don't align with that, I'm sorry.

I have a similar config on Gentoo, but it has issues playing accelerated videos. Could you please test the following steps on your machine and tell me whether you can replicate the issue?

1. Open a youtube.com video in Chrome.
2. Set playback speed to >= 1.25.
3. Check for synchronization between the video and the audio.
4. After playing an accelerated video for a while, the audio-video synchronization gets lost.

I'm unable to replicate your issue. I tried a few different videos (especially some of those GoPro videos provide good audio-video synchronization content in 4k). I used Chrome, but I can try chromium too. In my experience firefox runs smoothly while chromium tears and stutters, even with Netflix.

The kernel I'm running is agd5f's drm-next-4.8 branch.

Mesa 12.1.0-devel (git-b479c47)
OpenGL renderer string: Gallium 0.4 on AMD HAWAII (DRM 3.2.0 / 4.7.0-rc5+, LLVM 3.9.0)

Thanks for the test.

How about this: mplayer -vo gl video-h264.mkv

Installed mplayer just for you (I usually use mpv). Seems fine!

Is there an advantage to running agd5f kernel compared to 4.7-git on R9 390?

Yep, see this quote:

The pull request also contains patches which pick up new SMC microcode (with a _k suffix) for some SI/CI boards, which may improve stability for 390/390X users.

The performance in this kernel is much, much better than it was for me on 4.7. I wasn't able to do much beyond basic desktop usage. I also no longer have to set performance/high dpm manually to avoid the machine freezing up.

[fuzz]

I think that in the general stuttering will be solved when the market moves to >= 144Hz monitors. I currently have a 60Hz display, the next one I buy to replace it (don't know when) will run at more than 60Hz.

I don't know why they chose 144Hz to be the next standard refresh frequency.

Edit: 60*24 = 1440, so it makes sense to me now.

I agree. I decided to go with 4k over moar hertz for now, but when I can get a 4k monitor with 144 Hz for a reasonable price I will be happy.

+1 to the multiple of 24 thing... the industry is weird

[fuzz]

I just tried agd5f's drm-next-4.8 branch. I measured no performance advantage over normal linux-git (Shadow of Mordor, Tomb Raider, glxgears).



I have the _k patch as well (in normal linux-git). It lowers power consumption and keeps fan noise down.

I additionally have a non-public patch to lower the memory clock on R9 390. This reduces desktop power consumption by about 40 watts compared to running memory at the default highest clock. Automatic mclk adjustment has some issues unfortunately, so I am adjusting mclk manually for now.

Perhaps the _k patch alone solved a lot of problems for me.... I haven't tried it outside of the drm-next-4.8 branch. Everyone I've seen has claimed slightly different issues and kernel versions with the 390/390X.

There may be multiple issues being discussed here:

- reported performance regression on 290 (and 390 ?) which (AFAIK) affects the open source drivers in the 4.7 kernel but which has not made it into the AMDGPU-PRO kernel driver.

- stability issues, supposedly on 390 only, which the _k microcode has been reported to help with

Yes, I think the performance regression hit most (all?) 290 owners and only some 390 owners (myself being unlucky).

So this will be 480 VS 1060. At last a real battle, the winner will get my money.

Fight!
