    I suppose for same purposes why 7XXX turn into R9 / R7.

    or
    SI = Sea Islands (R1100, GCN 1.1)
    ?
    Curacao = pitcairn.
    Thx!

    AFAIR Oland was released after Bonaire (GCN 1.1).

    Curacao = Bonaire?
    Yes, I'm sure. Oland is SI-based. Curacao = pitcairn.

    Oland GCN 1.0?

    HD7790 is GCN 1.1

    All the HD7xxx cards were GCN 1.0.

    No!
    The HD7790 is Bonaire as the 260/260X are.

The 7790 was released 14 months after the first 7000 series cards and only 7 months before the first 200 series cards.
    7790 was always GCN 1.1, and yes, it was the prototype they used to test yields of the architecture.

    Code:
    [Tue Jul 22 22:17:52 2014] nouveau  [  PTHERM][0000:01:00.0] temperature (90 C) hit the 'fanboost' threshold
    [Tue Jul 22 22:17:55 2014] nouveau  [  PTHERM][0000:01:00.0] temperature (86 C) went below the 'fanboost' threshold
    [Tue Jul 22 17:09:01 2014] nouveau  [  PTHERM][0000:01:00.0] temperature (96 C) hit the 'downclock' threshold
    [Tue Jul 22 17:16:16 2014] nouveau  [  PTHERM][0000:01:00.0] temperature (92 C) went below the 'downclock' threshold
    PTHERM has other means to downclock GPU, and AFAIK it has the same settings as nvidia blob
    And nvidia blob manages to get temperatures over 110?C (no dust, fresh paste, compal JHL90) . Idle temperature is just 15?C higher on nouveau, power consumption is probably much bigger issue
    Also i have noticed that nvidia somehow has memory leaks and uses way more cpu/ram… I just hope to reach 14 days uptime again
    (About my portal2 testing: i forgot to test any valve maps … and fps drops noticeably there to almost unplayable level)

    Maybe it's time for modifying VBIOS before attempting honest benchmark? At least for the NV50
    I would definitely switch to open drivers but there are certain problems. First, this is a laptop. Second, the GPU I have (GT 9600M) is really very-very hot even while using nvidia driver. So I'm not sure how safe it would be to use nouveau since it has obvious problems with power management.

    Umm -- the power management on the OS drivers still causes at least some chipsets to get WAAAAY too hot. I mean as in uncomfortable to touch your laptop near your heat exhaust. It turns your laptop essentially into a mini-space heater and/or noisemaker from the sound of the system fans. This happens even if you have a USB cooling platform hooked up BTW.

    I deeply applaud AMD for their OS efforts and focus on buying their products because of it. But lets not pretend that things are hunky dory and that there aren't real issues with the drivers that can necessarily damage your system.

    Use fglrx. It just works. I've been using fglrx for more than 5 years and it worked most of the time. Yes, there are certain problems but at least it never crashed my kernel at random times.

    Tell me moar about it. I have 9600GT m in a laptop and you know what? Nvidia has only legacy support for it. Moreover there are kernel crashes from time to time which appeared some time ago and which nvidia is not going to fix anyways (there was a lengthy thread in nvidia's forum).

    So all your facts are the same as MS's "get the facts".
