    Perhaps you missed my post above - the scanline wait removes tearing, while being lighter than a compositor, no?
    In practice, it's pretty much the same. You generally only have time for one scanline wait per frame anyway, and if your image is anywhere close to the height of a frame, you end up waiting for almost an entire frame anyway. Additionally, a scanline wait stalls the 3D engine will you wait for the vline so during that time you can't be rendering something else.

    Plus, with a compositor, you can pageflip which saves memory bandwidth over a blit.

      No code for/discussion about Richland APU's (the successor to the current Trinity APU's)? Supposedly they will be launched on March 19th 2013 and apparently will be built with Piledriver cores and HD8000 graphics cores while maintaing the same TDP. Does anyone know if any of this is true?

        While AMD has yet to officially introduce their Radeon HD 8000 series, published today was the initial open-source Linux graphics driver support for handling the Radeon HD 8800 "Oland" graphics cards.

        AMD's been planning for a second quarter release of the Radeon HD 8000 "Sea Islands" GPUs while the first to arrive hardware will be the HD 8800 "Oland" graphics processors. This hardware that succeeds the Radeon HD 7000 series isn't as radically different as going from the HD 6000 to HD 7000 series, which yielded a better turnaround time with the initial HD 8000 series support.
        Just noticed that the article links the just-released driver support for Oland to an HD 8800-series part, presumably based on September 2012 rumours which described Oland as a 3.4 billion transistor upper-midrange part.

        Oland is actually a 6 CU part (ie same ALU count as the GPU on Trinity, but GCN rather than VLIW4). See Anandtech description of Oland/Mars :

        Oland : http://www.anandtech.com/show/6570/a...eries-for-oems

        Mars : http://www.anandtech.com/show/6571/a...n-8000m-series

        The "Oland" support we pushed recently was for the HD 85xx/86xx OEM and mobile parts announced in January, not for "HD 8800".

          Thanks for clarification!

          I was surprised to read that AMD postpones the release of the new GCN2 ASICs
          to late 2013 while the first bits of driver support hit the repositories.

              We were surprised to read that too. It's funny how when rumour A is replaced by rumour B people automatically assume that *we* changed something

                Thanks bridgman.

                Do you have any information about Richland? I realise that you can't confirm or deny the release date I quoted if it hasn't been announced by AMD marketing, but can at least re-share what they _have_ said so far? And maybe also tell us if AMD's open-source driver team are working internally on as yet unreleased driver code for Richland?

                  I have asked for clarification re: what we have officially said about Richland -- can't comment otherwise until I hear back.

                  We are trying to have launch-time code for all of our hardware now. The downside is that we need to understand and coordinate with our launch plans, which is a new challenge for the engineering team

                    ok ok. end of joking. I need to grab my fedora iso... its time for checking out systemd, gnome3 and r600g (unless fedora welcome me with llvmpipe )

                      It's official. AMD officials revealed to journalists during a conference call on February 15, 2013 that AMD will be releasing new Radeon desktop GPUs "from top to bottom" in 2013, though you won't be seeing the next-gen Radeon 8000 series graphics cards until late in the year. Instead, the company will be firmly focused on the Radeon 7000 series cards currently available on the market for the first half of 2013. In the meantime they plan to focus a lot of attention on aggressively developing drivers (I assume that means the Catalyst driver) and courting gaming industry partners.
