    I've just recently joined the iMac forums after ordering my first iMac about a week ago. There is plenty of helpful members that helped me decide on a few things. So I want to give back to the community and try to help someone who could be having second thoughts.

    I bought a base 27" iMac and ran a few tests out of curiosity. No screenshots but i wrote everything down.

    3.2GHz quad-core Intel Core i5
    8GB Ram
    1TB hard drive
    NVIDIA GeForce GT 755M with 1GB video memory


    Geek Bench (32 bit test)
    Single core 3280
    Multi core 10388

    Memory Single core 2776
    Memory Multi core 2996

    Boot time
    30-31 sec

    Disk Speed Test
    Write 183.9
    Read 182.7

    Cinebench
    OpenGL 53.21 fps
    CPU 5.84

    Launch iPhoto app(i had no other intensive apps to test)
    7.49 sec


    I then upgraded the ram with 16GB of memory from Cruical for a total of 24GB of Ram and ran the same tests

    Geek Bench (32 bit test)
    Single core 3355
    Multi core 10496

    Memory Single core 3115
    Memory Multi core 3299

    Boot time
    27.5 sec

    Disk Speed Test
    Write 185.4
    Read 181.5

    Cinebench
    OpenGL 54.01 fps
    CPU 5.82

    Launch iPhoto app (notice it launched twice as fast)
    3.31 sec



    i hope someone wondering how a base model 27" performs can benefit from this.
    i opted to return mine and upgrade to a 3.5 i7, 24GB of ram, 256 SSD, and the 780M gpu for maximum performance :cool:

    Geek Bench (32 bit test)
    Single core 3437
    Multi core 10920

    Memory Single core 2811
    Memory Multi core 2997

    Boot time
    30-31 sec (same)

    Disk Speed Test (same)

    I had no idea the ram would change the app boot times that drastically! Thanks for the great review!

    yes, very interesting. i dont see the correlation myself but i ran the test under the same conditions (shut all apps, shut down computer, boot up, and launch iphoto)

    yeah something doesnt seem right here
    750 - 53/54 fps
    775 - 89 fps??
    780 - 55 fps

    :confused:

    I know very little about Cinebench - downloaded R15 from the website and ran it three times - 87, 89 and 90 fps. The last was at less than full screen resolution, the first was at full screen resolution. Could be user error but thats what it says :)

    I have opted for the GTX 775M for a number of reasons as well and believe it to be a very capable GPU. I cannot wait to check out my unit and test it (it's coming tomorrow! FINALLLLLY!)

    Yeh I've been looking into this myself. I have ordered the 780m version, but I cant seem to find anyone who has done a cinebench result on the 780m, only on the 775m.
    Except for on here... but I cant see how the 780m only gets the same score as the 750/755... I'd expect it to be in the 90's at least.

    I just re-ran my cinebench test using the R15 program and it achieved 86.77fps with my 780m - still lower than the 89fps posted on the 775m.

    Obviously the issue was with the program difference.

    Curious why it benched slower.

    I am running the i5 3.4GHZ which benched 18% slower than the i7.

    Cinebench OpenGL sucks for performance scaling. Does not scale properly.

    These are impressive numbers! Alas, I have just a lowly 2011 base 21.5...

    IDEM?

    Seems strange that the 775 seems to get consistantly higher results in things lol. I'm hoping this is just a driver issue or something

    I just finished setting up my new iMac and here as some benchmarks:

    NVIDIA GeForce GTX 775M 2GB GDDR5
    3.4GHz Quad-core Intel Core i5, Turbo Boost up to 3.8GHz
    16GB 1600MHz DDR3 SDRAM - 2X4GB
    1TB Fusion Drive

    CineBench R15
    OpenGL: 82.55
    CPU: 530cb

    I've also tried some games and while I didn't measure FPS or anything else, I can provide subjectively opinion of how they performed (all native resolution):

    Civilization 5 - Flawless on HIGHEST settings
    XCOM: Enemy Unknown - Flawless on HIGHEST settings
    Cities in Motion - Flawless on MAX setting

    I'm pretty happy with the results :)
