About new imacs

The high end new imac has geforce gtx 675MX/680MX which is based on same core as gtx680 (gk104), just with less shaders (960/1536), so:

1) its gonna be beast mac, especialy 680mx, it’s just like desktop’s gtx680, just with lower clocks, ultimate gaming All-In-One computer
2) we will have better gtx670/gtx680 support

    Hi, i looked in that huge update.
    I found a new Nvidia related kext: NVDAStartup.kext
    Must be new – never seen before.
    I looked in (code): NVDAStartup NVDAType NVCLASS nv_drv OfficialNVDAStartup:
    NVArch NVDAHalnub Typeunmatched yes NVDAgl NV40 NV50 GF100 GK100 GM100 Architecture couldn’t be recognized! PMC_BOOT_0 = %p, PMC_BOOT_42 = 0x%08x
    ….

    Maybe probs for already working Nvdia gpus?

    Actually, the Geforce GTX 680MX is a full desktop Geforce GTX 680 with ALL 1536 CUDA cores enabled, just clocked lower.

    Etc,

    690 it’s a two GK104 chips in SLI on single card. The same can be done with two GTX680MX in SLI, but SLI isn’t available under MacOSX.

    I know about SLI, maybe better OS X support will be?

    @Andreas/Mitch, this seems to be already on the 304.00.05 (not 304.00.00) driver for 10.8.2 scripts. Trying to use the actual drivers on a gtx 680 gave me that NVDAPreset was unknown, after a “NVDAStartup: Official” output (didnt try to edit matches, i don’t think we have a difference for good on this with 304.10, so i just returned to 304.00.05f10). That remembers me the old times of drivers available while in tests (example: VIA on 10.4.3 to 10.4.4) that became locked afterwards.
    ometimes it seems that the workers inside apple likes us, but maybe their bosses doesn’t.
    And it seems that “nVidia pokes Apple” on that one.
    Shall Reatail drivers continue here to stay!
