    Michael Why compare radeon vs. amdgpu-pro? Why not compare amdgpu vs. amdgpu-pro?

    PS: Okay, I think I understand: For whatever reason, the 3D driver for Volcanic Islands is still called "radeonsi", even though the 2D driver is being called "amdgpu"........................:

      The 3D driver has been around for years and doesn't change names.

      The kernel driver is new, and lets them run their proprietary userspace driver as well as the Mesa one on top of it, so it got a new name relating to the hardware it supports.

        I think you are confused? I compared what is AMDGPU+RadeonSI vs. AMDGPU-PRO... Those are the only two options for Polaris cards... Were you thinking I somehow tested R600g (pre-GCN)? Or that I was using Radeon DRM (not supported by Polaris at all)?

          "radeonsi" is a name of the mesa dri driver whatever kernel driver is used (that could be radeon or amdgpu).

          On the other side AMDGPU-PRO's 3D driver is named "amdgpu".

              shader caching can have small impact on benchmark numbers, but here problem is something else

                did it not work?
                otherwise it would be nice to see this benchmark included
                It was rather an open question in that article. If my memory serves me, no, it didn't have proper benchmarking support at the time and I ended up returning the game... If anyone has the game and can confirm differently with any newer patches, happy to re-buy the game.

                    1. For Deus Ex, in the recent Windows vs Linux test the 480 on Mesa was running at 64 fps with low settings (vs 14 here), 44 fps with high settings (vs 9 here). In both cases the results in that test were quite a bit higher than even the PRO driver on 470 here.

                    2. For Bioshock Infinite the PRO driver was 20 fps faster than earlier 480 results (~80 fps previously, 100 in this article) and the Mesa driver was >20fps slower than earlier 480 results (~80 fps previously, ~55 in this article).

                    Either way, will be interesting to see what the results look like next time the 480 comes up in rotation. Thanks Michael.
                    Right, I hadn't been using the RX 470 much for comparisons since it is factory overclocked and from my earlier RX 470 tests of this card was so close to the RX 480 that I didn't bother testing it much. But now that I re-racked this particular Xeon system I had been using up until I switched it for the Core i7 7700K system now, I decided to put in the RX 470 into this lower-racked system to make for other benchmarks since seemed like the logical choice for a newer Radeon card that I don't otherwise test a lot due to its factory overclock. But now with that RX 470 being "permanently" put in this racked system, it will be benchmarked more. Happy to try some 17.0 vs. 17.1-dev benchmarks or so on this system if you think it might be a regression for those games or any other ideas to explain the difference?

                      I don't think it is mesa regression but instead suspect setup error first, otherwise it might only be something acis specific for both drivers... as it can't be also that here DiRT Showdown crashing with AMDGPU-PRO 16.60, but previously it don't crashing with same 16.60

                      There it works fine:
                      http://www.phoronix.com/scan.php?pag...0-nvidia&num=2

                      And here you commented "DiRT Showdown had ran fine on RadeonSI but was consistently crashing with AMDGPU-PRO 16.60."
                      http://www.phoronix.com/scan.php?pag...60-rx470&num=2

                      Probably easiest if you try to reproduce the issue with that, try again RX 470 and if it still crashing DiRT, replace it with RX 480 and if that don't crashing there, we have a culprit But if RX 470 now does not crashing anymore rerun this benchmark again what to say else other than "shit happens" if it is setup issue
