In this clip Hardware Unboxed says that 8GB GPUs are okay up to 11GB VRAM usage, but going beyond 12GB kills performance.

Can someone explain how this is possible? Does it have something to do with your normal RAM being used as some sort of replacement to some degree?

I imagine it has to do with texture compression and it’s respective ratio that is probably limited by the gpu’s decoding speed? But I could be wrong.
