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:
 
Here is similar for 3.4GHz quad-core Intel Core i5 GTX775M 2GB
8GB Ram
1TB hard drive
NVIDIA GeForce GT 755M with 2GB video memory


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)
Write 183.9
Read 182.7

Cinebench
OpenGL 89.25 fps
CPU 543 cb (I have no idea what this means :)

Launch iPhoto app(i had no other intensive apps to test)
7.49 sec (close - 7sec small lib)

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

89fps in cine bench !!

I only got 55fps on my 780m

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 :)

http://www.youtube.com/watch?v=wDUuDzmNQHE this guy got about the same - with the same machine

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.
 
so 775M diablo 3 1440p high settings OSX 90fps
780M I D E M OSX 85fsp


both 8 Gb Ram and i5 3.4
 
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

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 :)
