    x1270 belongs to which chipset?

    Here in this source -

    http://wiki.x.org/wiki/radeon

    It says -

    R100/R200 (Radeon 7000 – Radeon 9250) and R300/R400/R500 (Radeon 9500 – Radeon X1950) class chips:

    and

    R600/R700 class chips (Radeon HD 2300 – Radeon HD 4890):



    Which means that R300/R400/R500 has the graphs chips Radeon 9500 to Radeon X1950

    and R600/R700 has chips Radeon HD 2300 – Radeon HD 4890

    I have RS690 chipset which must belong to R600/R700 category and has x1270 card...which is strictly against what that page states.

    It also states that R300/R400/R500 contains all chips till x1950 which is also wrong.


    Now the official wiki page about AMD GPU -

    http://en.wikipedia.org/wiki/Compari...ocessing_Units

    Confirms that RS690 has x1200 graphs chip which is supposed to be related to x1270 (but the drivers don't work)

    We also have a separate page for the 690 series chipsets -

    http://en.wikipedia.org/wiki/AMD_690_chipset_series

    Which confirms that RS690M has x1270 graphs chip.

    Now...I've realized that no drivers except the opensource radeon drivers work; I wanna know if my 3-d is stable in accordance to the developers or not... cause I really don't know which category my chip belong to following all this.

    I even have a feeling that R600 is very different from RS690; and I think the developers do not know about this...or do they?

    Re: x1270 belongs to which chipset?

    I have RS690 chipset which must belong to R600/R700 category and has x1270 card.
    The RS690 is a mutant. In terms of basic fabrication/modesetting, the 690 resembles low-end R600 hardware. The 2d programming model is close to the R500 (Radeon X1k) series. The 3D hardware is actually derived from the Radeon X700 (R400) family. Basically, Catalyst/fglrx is a no go on this chip with X server >= 1.6 (i.e. Jaunty)
