When you look at the unigine-heaven 4.0 results the 770 and the r290 are good contenders. Same for 2 GPU-test results and for 1 luxmark. But all those are no real world games. The only real game benchmark michael delivered here is OpenArena and Xonotic. Where are Prey and the other games he used to show? Source games would definitely show us much more meaningful results.... and yes michael, I know about the problems benchmarking those... however, a benchmark-selection with acually two games for 14-gaming-gpus is kind of wrecking phoronix... :/

    Not sure how you could paint the 290's support in Linux as anything but a wreck.

      You can't surmise anything by that. The PS4 is not using Mantle, it is not using openGL, it is using it's own API. Saying that you can surmise better support because of the PS4 carries no more weight then the then AMD's performance improving because of Windows DX 11.1 support.

        I didn't know how people still thought that AMD has better OpenCL performance...

        Yeah it has better performance when is a simple calculation.... if you try to make something bigger then the performance drops drastically and eventually just stop working.

        I know that complexity has a performance hit but amd has much more performance drop than the other vendors and eventually the Opencl kernel stop being able to compile in amd when the rest (intel/Nvidia) still works fine.

        AMD stated that they're working on it like 2 years ago... but there's almost no progress done.

        So, take care if you buy an AMD card planing on doing some big stuff with Opencl.

        PS. Does True audio works on linux?

          Ding, ding, ding.... we have a winner! You are absolutely right, the more complex the calculation the more AMD's performance declines.

            I did not. Read my post, and the linked one too.
            It is a wreck in most benchmarks shown here. My question was if the shown benchmarks are even relevant or if we need more games (assuming WE are gamers)

              When i read the word "wreck", i assume it doesn't work at all. Because when my car is in a wreck, it's completely stopped. 290 support seems to work just fine, it's just way slower than it should be.

              But i agree things are really bad in terms of performance.

                Precisely!

                I agree completely!

                A "Wreck" would mean I would not have been able to play Metro LL maxed out, nor Serious Sam BFE maxed out, nor Wargame EE maxed out, nor smooth graphics with Valley, Heaven, Tropics, Sanctuary!
                Well, for the games above, I played them all MAXED out! Even overriding AA and Anisotropic filtering and dialing up the settings to MAX with Edge-Detect AA on CCC.

                I agree the Windows benchmarks and their Nvidia counterparts show us how far the R9-290(X) can go still. But it isn't a hardware problem/limitation, NOR a problem (or wreck) at all since all the CURRENT hardest hitting games on Linux can be MAXED out with smooth playing; with consumers getting what they want out of the games currently available to play from Steam or Desura!

                As for the "FPS" difference between Windows benchmarks and Nvida counterparts; it is just a matter of time as Valve and AMD have already said that AMD-SteamMachines and their specs will be out next year AND that won't happen without AMD sorting out the driver to make significant improvements. By the latter half of next year, it should be close to parity if not better (*better for Mantle enabled games).

                  All the games tested though (on high settings) played at higher than 60fps... so.....

                  I don't see why you would consider it a wreck. Since the lower than expected performance isn't a problem for current games on linux. As long as they get the performance improvments in before more demanding games show up, I'm ok.

                    Wreck is too harsh

                    Agree.

                    "Wreck" normally means that it's completely dead. Apparently it's not the case here.
                    True is that R9 290 on Linux doesn't run as well as it is on Win, it's still capable to deliver 60+FPS in all games in benchmark.

                    In the other hand, I quite understand Michael's feeling about his near $400 investment on this card.

                      Which people thought that? Anybody with minimal knowledge about GPU compute can tell it more precisely than that. For one, don't forget that NVidia consumer cards are intentionally crippled in DP (a Radeon HD7970 is more than four times as fast as a Geforce GTX 680 in Linpack). AMD usually does better for workloads which are ALU limited. NVidia often does better for workloads that are limited by something else (e.g. I/O).

                      A nice explanation can be found here: https://en.bitcoin.it/wiki/Why_a_GPU...Nvidia_GPUs.3F

                        I hope AMD improve the drivers before Rome II Total War comes out on Linux!

                          Every time i update my repository with the latest fglrx drivers i think later that it was more or less useless effort. Ok, with the latest 13.11 beta 9.4 it gained kernel 3.12 support, but thats it. fglrx driver is pure crap with my hd 5670 and l4d2 on linux. even a gt630 kepler is feeling better in that game and that card is slower due to the stupid lag with the autodetected settings. ok, you could use lowest settings but why does the game detect higher ones... the fps jumps from 50 to 299 and back all the time, if it would not jump that often it would be much better. I think a highend card would not be that critical as the raw performance is higher but i still would only buy nvidia for linux. Now killing floor got some nvidia bugfixes as well (the only game with nvidia rendering errors). Most likely the oss drivers would work better with source engine than catalyst - maybe i get mesa 10 running with wheezy, lets see...

                            mesa 10

                            if you use a ppa or repository its not hard to get it running - and with that card you definitely go oss. You will have regressions in games that use openGL 4 like serious sam but almost all other games should work smoother now than with catalyst, from all I have heard so far, cause the fps is more steady AND on the same absolute level.

                              updated test possible?

                              any chance someone can do a quick rerun of the test with the 290 and the 14.1 beta 1.3 driver?
