    yeah, "eventually" every card is going to be supported. Just wondering if the RV740 has some architectural changes that need lots of additional work, or if it can be driven by the existing code with slight modifications. In other words: will RV740 owners wait longer for 3D support than RV730 owners?

    I've been waiting to ditch my 7600 GT for quite a while now. As soon as there's an ATI driver which allows 2 monitors, fast 2D, composite (kwin) and Diablo2 on wine (openGL), I'll buy. And since John and Michael keep talking about every tiny step that's been done, it's difficult to not get constantly excited

      Afaik there shouldn't be any architecture changes of consequence within r6xx-r7xx but bridgman might want to give a more authoritative answer on that. I unfortunately can't give any definitive data on about anything since most I do is listen to what other people have told about the current state; the information you seek is probably in the specifications AMD has published.
      ps. I think this is legal-wise a significant step if not for any other reason.

        Sorry about the delay. The news story is posted now.... I had written it up in advance, but when hospitalized it did not work out so well for posting the story

            hospitalized? why? what happened?
            Hope you'll be back soon and stronger

              Another "best wishes, get well soon" message here. We were hoping nothing had gone wrong -- normally we have to hustle to keep up with you

              We do not discuss unreleased hardware, but all discrete GPUs in the 7xx family have very similar 3D programming characteristics so I would not expect any delays in support other than getting production boards into our developers systems. Each different GPU normally needs some code tweeks and I expect future 7xx parts will be no different.

              So... yes, the wait will be longer, but only because our devs already have production rv730s but don't have rv740s yet.

                Sorry, I was unaware it was unreleased. I somehow assumed no one would start planning purchase decisions for something that doesn't officially exist yet. Anyway.

                  I wish. This is the PC industry; by the time a HW vendor actually *ships* something everyone regards it as obsolete

                    as soon as you buy, the value of your hardware is -50% (and the minus means you need to pay to give it away)

                    nice old crazy world.

                      I thought rv740 was already shipping in laptops?

                        I'm not totally sure of the status; we mentioned it at CEBIT IIRC, and I'm sure that OEMs have them, but didn't think there were any in public other than leaks. The lead time from part availability to laptops-in-customer-hands is pretty long; usually months not weeks.

                        Tell you what... if it's up on amd.com I'll talk about it, OK ? Hold on a minute... OK, so looks like the mobile parts are up on amd.com :

                        http://ati.amd.com/products/Mobility...860_index.html

                        So, yeah, the 3d engine shouldn't be hard to get running but the display blocks changed again IIRC. I expect display will take more fiddling than 3D to get running. Realistically we'll need to wait until production desktop cards are shipping but shouldn't take long after that.

                          There are some previews of test samples around the net, and some sites mention a release date of 28.4. No idea what parts of those information are "official", "leaked" or even "plain wrong".
                          Was just wondering if it's worth keeping an eye on, or if it wouldn't be an option due to driver trouble anyway. Sorry for being a bit impatient.

                          Thank you for your reply john. If it takes until may or june until the hardware is available and 7xx 3D works, I'll wait. Feels good to have a palpable date

                            FWIW glxgears almost works on my HD3850 AGP, it segfaults every time at 30 seconds and there is so much debugging output that I have to redirect stderr to /dev/null, but I do see something - not quite rendered properly and it doesn't resize properly (the gears resize but do not stay within the window if reduced and if enlarged look like the shot below).

                            It's great to have something to test though - so thanks to all concerned.

                              Cool, I'm glad someone got it working.

                              It did run better a few weeks ago before texture support was added; I suspect something got broken either then or during the subsequent cleanup before release. We'll figure it out next week...

                                Heh, looks like the shadows on the gears were calculated horribly wrong in all three gears. (Kinda interesting that it seems some stuff in the red gear is rendered *completely* black)
                                Edit: Oh, wait. Actually all three gears have some of their lower-right portions rendered completely black. Me blind.
