    Phoronix: Sapphire Radeon HD 5830 Extreme

    This morning Sapphire Technology is announcing a new Radeon graphics card. It's not though part of the Radeon HD 6000 series that has recently seen the launch of the Radeon HD 6790 or even the Radeon HD 6450, but rather it's a Cypress-based part. Yes, as in the Radeon HD 5800 series. This new graphics card is the Sapphire Radeon HD 5830 Extreme and it has designed to deliver the best performance for the ~$120 USD price point. Here is our look at this new graphics card with accompanying Linux benchmarks.

      I can't believe the power requirements of todays video cards, its insane!

        An oss driver comparision would be also cool. I found out that one xorg.conf option extremely improves ati oss driver performance for games: SwapbuffersWait - set it to false and you will see what i mean. For nouveau another tuning is required as it defaults to run the cards at boot clocks. Best ask the devs how to switch it, it is a tiny bit complicated but the result is worth the effort.

            So much for the "you don't need a xorg.conf anymore" that gets tossed around in the ml/forums that some X / kernel devs like to throw around.

              The oss drivers are tuned for stability, not performance. This is true that a tool should be created to tweak the xorg/mesa options for stability/performance/visual fidelity. Just like amd's control center and nVidia's nvidia-settings

                Interesting card for the price point.
                Given than it's also roughly 20% more expensive than the 5770, seems the HD5k-series scale pretty well here performance wise (Can't really say the same about the 6870 though). Personally I think I'd still go for the 5770 because of the single 6-pin PCI-E.

                Side note, given the special cooler, temperature levels would have been interesting. (Acoustic levels too, but that would need extra equipment).

                  You don't need it if you are happy with the default settings. That's all that anyone has ever claimed

                  It's not like your system won't boot if you don't provide a correct xorg.conf, as is the case with some user-friendly blobs.

                  It's also not like you have to block driver updates so they don't bork your computer as is the case with some user-friendly blobs

                    Actually GKH was the one that I had in mind with a recent GoC project SaX3. He was saying it was no longer needed to have such xorg.conf helper apps.

                    * AMD blobs. Nvidia blobs haven't needed xorg.confs for a long time now for basic usage.

                    Dkms handles this, as do many distros update their blob packages to accommodate the update. Not a big issue.

                      Linux needs A LOT of such tools yet for hardware specific tweaking. Sound / TV Cards / specialty cards / motherboard features (even things like nTune/Overdrive) are items that immediately pop to mind.

                        You claim that only OpenGL 3.2 is supported on the front page (which is likely what the box has printed on it for this part, because nobody markets OpenGL effectively) but this part clearly supports OpenGL 4.1 with any moderately recent Catalyst driver version. Heck, one of your screenshots later on even shows that.

                          That also struck me as odd, since Phoronix main subject is graphics so it's not like Michael doesn't know that.

                          It's the first time I saw anyone suggest such a thing. Makes a lot of sense though. There's driconf but it's not as user-friendly as any of those tools.

                            Well, maybe a phoronix reader would be interested in doing this. It doesn't sound like something hard, it's just that the creator would need to read the news and maybe ask some questions to the devs. Gather and put documentation in a single place could already be a good start

                            Important settings:
                            - wait for vblank: activated by default on radeon (and intel?), deactivated on nouveau
                            - page flipping: activated by defaut on nouveau and intel, don't know for radeon
                            - color tiling: deactivated by default on radeon. I can't remember if nouveau/intel support is implemented or not
                            - surely some more things

                            Seems like a weekend project to me

                              I think the point that there's a claim you're supposed to need to create an xorg.conf file anymore is a good one.

                              The excuses and replies to this was poor. I agree with deanjo.

                              I think it is annoying when you spend money on the card and there's no xorg file but to be able to use your graphics card, you need to edit/create an xorg.conf file.

                              That's not even the problem. I suspect there's a trial and error process of constantly trying different configuration settings until one is found that achieves what one wants or to get optimum settings (or even ones that work).

                              How many users are content with defaults (i.e. no config file)? Of course, it must be complicated to adapt or address every (new) gpu but the point remains. There shouldn't be a claim you don't need xorg anymore. IMHO.
