    Phoronix: The OpenGL Speed & Performance-Per-Watt From The Radeon RX 480 To HD 4850/4870

    With the Radeon RX 480 Linux review now being out of the way and our various other RX 480 Linux benchmarks, the latest results I have to share with being a benchmarking fanatic are RX 480 results with high-end AMD GPU tests of each generation going back to the Radeon HD 4850/4870 (RV770) days. This article has high-end GPUs from the RX 480 to RX 200, HD 7900, HD 6900, HD 6800, HD 5800, and HD 4800 series compared side-by-side with the latest open-source Radeon Linux graphics driver code. Not only is the raw performance being looked at but the system power consumption was also being polled in real-time for looking at the performance-per-Watt too. For any other benchmarking fanatics curious about the Radeon GPU evolution over the past eight years (RV770 launch in 2008), here are the numbers to enjoy.

    Very nice tests, Michael!
    And good work AMD!

    I will say what many other people have been saying these days: my next PC will have either Polaris or Vega. But I'll wait for Zen to see how it turns out.
    I was originally waiting for Skylake (from Sandybridge), but for me at least it turned out not to be so impressive. Probably because intel pumped it up so much. The price is also not a big incentive.

      The HD 4850 results indicate a higher FPS than the other older GPUs since it failed to handle the OpenGL tessellation code path.
      It didn't fail to handle anything, the hardware just doesn't have tessellation!! When HD 4850 was released, tessellation didn't even exist in DX and GL APIs.

        It actually does have tessellation and it called ati truform, been there from the radeon 8500 era. But of course you are right, tessellation which hd4850 uses is not compatible with OpenGL4 and DX11 api tessellation and thus not usable.

          Just a note: Replacing "Relative Performance" with "Relative Performance Per Watt" in the charts might improve readability of the article.

            It usually says XXX Per Watt, but then when I normalized the values, that pass overrode that string. I guess I should just patch pts_Graph to append "Relative " to as a prefix of the string when doing that pass.

              to be fair, ATI TruForm was available since Radeon 8500, it's just that nobody used it until it became part of standard API

                Oh no, RX 480 has joined the green team

                  Looking nice and the progress from one generation to the next is quite visible. I wonder how RX 460 (Polaris 11?) / 470 / 490 will be placed in comparison to the RX 480. Polaris 11 is supposed to be less punchy but even more power efficient.
                  Stop TCPA, stupid software patents and corrupt politicians!

                    Well man, this is Marek. He knows best what tessellation is, especially when he actually did r300( where first TruForm hardware appeared) driver for Mesa.
