      Eh?
      The 480 is NOT meant to compete against a 1080 or 1070. 1080 is high end, 480 is mid range.
      AMD's high end is called Vega, and that will ship before the end of the year.

        We have ROC running on a Polaris 10 internally (as of a couple of days ago) but not sure yet which public release will pick up the support.

        In fairness, Creak was talking about Gflops/price ratio not absolute performance.

          That's very clever posting about sones, you get a gold star. To convert from a microphone sample, need to take a Fourier transform, then integrate some function of each frequency. We can store this function as a high resolution texture, then the Rx480 could do the multiplication.

          ​​​​​​​Anyway, I'd like to see DooM results, but I know DooM gets 0fps even in Wine

            what we really want is this: https://en.wikipedia.org/wiki/Sone
            and you can not measure "Sone" with a mic.

            A Sone measurement device is very complex. If [email protected] go for mic and decibel all results will be useless for "Humans" decibel results are only useful for Robots.
            A mic will give you response, but without calibration you've got no real way of knowing if that response is a 1:1 map to decibels or not - and it probably isn't, because a mic is an analogue instrument. For pretty much any analogue measurement calibration is a must if you want to get accurate results.

            As to Sone: I'm not one of the people who think Sone is particularly useful because it tries to standardise human hearing response, which has a pretty huge variation. Decibels may not be perfect, but a) they're the standard that is currently in use, b) they are accurate when comparing the same types of sound, which is the case here as graphics cards tend to use pretty physically similar fans and c) they're an SI unit and not a subjective measure based on a notional average of human hearing. I'd say that proper accuracy in this kind of experiment would only be achieved only by giving a Decibel reading + a recording of the sound in question, so anyone interested in how loud the sound is perceived to be can recreate the sound at the required volume on their own machine.

              If you start to measure the correct "Sone" the companies would start building "Sone" optimised designs. and everyone would get a benefit. for example a fan can run at multible RPM speed and if you know witch RPM result in high Sone you can only use RPM numbers which are less noisy.

              If you are a professional you use Sone

              If you are a idiot with no clue at all you use Decibel.
              And probably an echoless chamber ...

                    Is this due to the efforts of letting OpenCL run over ROC or is P10 really meant for hpc, too?
                    I thought it'd be a "gaming-chip". Does it provide MxGPU and FP64?

                    OK, guess you can't tell us yet...
