Show us your CUDA cores in 675mx in iMac

the answer is the first quoted sentense, dude. modern games require more than 1gb of vRAM for 1080p, not to mention 1440p.

Ok but *why* does higher resolution need more RAM.... guess I'll just look it up.

The real answer is that the higher the resolution the larger the image assets that must be loaded per frame are...so a lower VRAM will be a bottleneck in frame rate...that being said, many/most current game require 512-1GB of VRAM so the 675MX more than fits the bill...looking ahead games will start benefiting from more VRAM

Ok, there are conflicting reports that the actual CUDA cores in the iMac version of the 675mx are closer to the 680m, and that the 675mx used in the iMac is a rebaged 680m...which brings it much closer to the 680mx in terms of performance. can ANYBODY confirm? It would require using windows under bootcamp with a card specs app. Im more interested in someone who has a more recent iMac with 675mx (Feb-March+ build), please post a screenshot for us, thanks!

Look, i don't show my "Cuda Core" to just anyone.

I'll just leave this link here, ok? It's in Russian, but the sheets are pretty demonstrative. Each game has two charts. The first one is vRAM allocated by the game, the second one is RAM. Note that those titles are from 2011. Just upscale it 1.1-1.5 times for 2013 titles and you'll get what I'm trying to say.
Here we go!
