AFR. there are effort to bring back SFR with Mantle but they still did not solve the main issue with SFR that make GPU maker end up choosing AFR over SFR in the first place: scaling.

Thanks. I've always had this theory that in SFR, dual cards (SLI/CF) could effectively combine their VRAM because each card would be only having to render part of a frame. Hence, each whole frame would be using both sets of VRAM. I always get an argument with that one, lol.

But it's a moot point if SFR isn't used any more.

AMD claim it is possible to combine VRAM with low level API multi GPU (though they did not mention if it's based on AFR or SFR or something new entirely) but to this day they never show us how that's work in real world situation either despite the claim.
