Doubts on 6970 future in OSX

According to latest leaks 6950/6970(Cayman) gonna be the only cards with VLIW4 arch. And since Apple never used and most likely will never use vliw4 cards, we may end up with no Cayman support in osx drivers at all( with patches – on incomplete level). It can be 4890 story all over again.

    I am very very sad to hear this 🙁

    May need to upgrade to a 7XXX card then?

    Not sure how reliable this info is–vliw5-architectures.aspx but it suggests that the Cape Verde (HD 7500, 7600, and 7700) and Pitcairn (HD 7800) are all going to be VLIW4 with the lower end parts (7200 and 7300 series being VLIW5) The 7900 series is GCN which apparently is a whole new can of worms.

    That info is old, Andy, new info is – < = 7600 - vliw 6 rebrands (from semiaccurate), >= 7700 – gcn (other sources)

    Did u see how much secrecy (even more) over pci-e 3.0?
    I wonder how closed will intel pci-e3 arch support will be to us.
    I imagine if Linux did not exists… in the end it makes unix/NOTunix be the salvation of who wants info on how the chipset you bought works.
    Until when will A. ping-pong us on nvidia and amd/ati?
    You pass months researching and in the end, all your time was lost in another unsupported architecture.
    Someone should launch an “IT-leaks” to solve this closure…
    just thoughts…

    What have we all learned from this?

    Never buy the best GPU available that a company produces (not including the HD6990/GTX590), high possibility OSX will not properly support it.

    We must hope, maybe Matser NETKAS can Realse a Driver for 6950 / 6970 that have no Cold BOOT-Bug and Maybe Apple will suppoort the 69xx Series hink it is Christmas

    It’s not being the best GPU that is the problem, it’s being the unique, low-volume GPU. It’s obviously much more favourable for Apple to support a whole family of GPUs with a common architecture/driver than to split development time over many different architectures. In this case though, it’s probably the delays in Sandy Bridge Xeons that killed it, since that pushed a possible Mac Pro refresh back into the HD7000 series timeframe.

    Isn’t Trinity supposed to be using a VLIW4 core in the future?

    Guess we’ll see HD 7xxx support in OSX soon – less heat and less power requirements – fits so much better into Apple’s product line than the 69xx series.

    Did you see this page almost 2 month ago. Saying in this article all 7000 series are VLIW4. Except 7950 and 7970 are GNC.

    I was checking out InsideMacGames and came across an article with Advanced Micro Devices’ Chris Bentley, the company’s Mac 3D Manager.

    Quote: “Finally, as I mentioned above, the biggest change for 3D in Lion was OpenGL 3.2 support, which included 16 new extensions supported on all the drivers from the AMD HD Radeon 2400 on up to the AMD HD Radeon 6970.”

    Soooo, why is there no full support for the 6970HD? 😛
