    Now that many 27'' iMacs are out there in the wild, it would be nice to know how the default 675MX stacks up against the 680MX. A head to head comparison could be useful as well...

    So anyone with the 675MX done any benchmarks yet ?

    Im guessing 99% of people that got the top 27" would have upgraded to the 680mx, i know i did and i don't even game on my Mac but i know the resale will be much better with it.

    How do I test?

    I chose the 675MX, but I'm not sure how to test it. What software should I use?:confused:

    Nice! I guess this is Mac right ? It would be nice if you could also run them in boot camp just for comparison, if you can. I also post the early benchmarks from the 680mx thread as posted by Fenn

    Don't bet on it. In the PC market the 680 is already surpassed.

    The GTX680 has been surpassed by the GTX690 for a while, but I think the 680MX still reigns supreme among the mobile chips? Either way, GPUs are constantly being updated ; )

    That difference between 675 and 680 is not that impressive no?

    Yep, that's far less difference than estimated by the pure specs.
    Don't see an advantage worth 150,-

    Hi, could you please tell me whether you ran the Heaven benchmark under OSX or Windows and what your exact settings were?

    All were done with OS X. I won't be trying it out with Windows, sorry.

    Here are the settings I had for the benchmarks with Heaven (mostly default):

    Render: opengl
    Mode: 2560 x 1440 fullscreen
    Shaders: medium
    Textures: high
    Filter: trilinear
    Anisotropy: 4x
    Occlusion: enabled
    Refraction: enabled
    Volumetric: enabled
    Tessellation: disabled

    Thank you! I'll check my settings later, but I think those are actually the same ones I got as well.

    Got the same score as above with heaven engine. Marginally worse than 680MX.

    It is, which is quite surprising. With 2-4 FPS there is no difference. Did you run the benchmark in Windows as well or maybe even have some numbers from games? And does anybody here have results from the 675 with i5?

    Updated: just noticed the first results were with an i5, so no difference there either.
