16-Way NVIDIA GeForce vs. AMD Radeon Comparison - August 2017

[Masush5]

Is anyone else on the thread running amdgpu+radv on SI today ?

Not personally, but i've seen this bugreport: https://bugs.freedesktop.org/show_bug.cgi?id=101334

It do look good except for Dota 2 which could be better.
It will be interesting to see where Vega fits into the equation on Linux. Yes it will be interesting but maybe you already knows but i guess we will know how Vega 64 performs on the 14th of august.

radeonsi vs amdgpu vs radeon confusion: https://people.freedesktop.org/~mareko/dot_mesa.png

radeonsi is only a piece of the puzzle. amdgpu and radeon are other pieces. You can choose some pieces (amdgpu vs radeon), but you'll always use radeonsi in both cases.

That explains how dual radeaon graphic cards works somewhat. I have an interesting case of one card using amdgpu (iIntegrated CIK) and another radeon (dedicated SI). amdgpu on SI card is currently broken by rendering noise although fix is on the way.

I cannot use amdgpu on my dedicated R5 M230 (SI) using mystro256 kernel-mainline repository due to this bug

1. With RADV from mesa 17.1.x I had rendering issues in Serious Sam Fusion on Ultra settings. Haven't tried newer mesa yet.
2. Tiling is currently broken for OLAND: https://bugzilla.kernel.org/show_bug.cgi?id=194761

Haven't tried it as of yet, but I have contributed a patch or two during SI bring-up. Maybe I could check it on something more important than a Vulkan demo now?

(I am currently awaiting Vega, but it still depends on the performance and price...)

just chime in for bridgman i'm using a xfx rx 480 4gb with arch linux stock 4.12.4 kernel an mesa git from this persons repo, LH-mesa-git-repo http://pkgbuild.com/~lcarlier/mesa-git/x86_64/ been playing an beat story line in mad max mostly using vulkan but a few time it broke an had to disable the vulkan options for it to play in gl. my setting are high at 1080 vsync off.

In my original post however, not only did I confuse 'radeon' (the old <GCN 1.2 kernel drm driver) with RadeonSI, but I also assumed that RADV would work with radeon (I now understand that RADV is an interim alternative to AMD's currently proprietary Vulkan userpace driver and that RADV needs amdgpu).

How do you run Vulkan on hardware that does not support it anyway?
(cards not supported by amdgpu)

Quick Q, is that fps-lock set on 30 for civ6.

Don't have the game, but if that fps on *1080p* is real unlimited framerate, then I'm really surprised... o_o

It's just one of the most CPU-intensive games ever made. A CPU that could remove the bottleneck does not exist yet.
