Features: Nvidia vs AMD - Page 2

post #11 of 15
Perhaps cumulative was a poor choice of words, sorry if it was confusing.

In SLI the data is mirrored, and each graphics card uses its own memory to render a 3D frame. The OS will show a memory size that is found on a single GPU. So it's not that the additional memory isn't being put to work, but that same data gets copied onto both cards.

just to be clear . . .

2GB + 2GB = 2GB on both gpus.

It wasn't cumulative that was the deal breaker, it was the statement "If you have two 2GB GPUs, you have 4GB available in Crossfire." which I do believe is certainly not correct.

Well I still feel this gen that AMD has the advantage with 3 monitor setups because their GPUs come with more VRAM out of the box.
