Request: Do you have a 675MX or 680MX equipped iMac?

[cal6n]

If possible, could someone who has the CUDA drivers installed post screenshots of the CUDA-Z window showing the "Core" and "Memory" sections for iMacs with either the GTX 675MX or 680MX fitted, please? I'm interested in comparing the specs with the GTX 670 I have in my Mac Pro.

The card performs admirably in all applications except Civ 5 and Aspyr support are particularly arrogant about my problem, waving the "unsupported" card like crazy. I understand one of these cards is really a downclocked GTX 670 desktop chipset and I'd like to try editing my BIOS ROM to emulate it precisely.

Ta!

Sometimes searching the forum will get you the answer you are looking for. In this case, I believe your answer is in this recent thread.

Oops! Thanks.

Looks like the 675MX is a downclocked 670, while the 680MX is a downclocked 680.

my sister has the 675mx

Thanks, but I have the info I need for now.

It turns out my card isn't supported by NiBiTor yet.

GTX675MX is actualy GTX680 with higher memory clock so I prefer to choose 675

Why did you post this?

Things to note:

1. The question has already been answered.
2. You have posted a link to exactly the same thread as the first response.
3. You are completely wrong. The GTX 680 has 8 multiprocessors with 1536 CUDA cores, while the GTX 675MX (in common with the GTX 670) has only 7 multiprocessors with 1536 CUDA cores.

1 and 2 my bad
3 I thought you compare mobile chips as long as iMacs have mobile chips in every generation not the typical desktop versions. I really don't know the difference especially when the screens and confirmation in that topic are from me but if you insist...my bad

I did comment in your other thread, but I suppose i'll do it again. No matter how much you want 1 graphics card to be another it's not happening. The better card is the GTX 680MX.
