Speaking with Nvidia, however, it wants to widen its own version out to Intel hardware, and specifically to PCIe 3.0 systems too. It has the feature working in the labs right now, but Nvidia hasn't given us a final date for when it's going live. Though I'd be surprised to see the
RTX 3080 getting support for the feature before the start of 2021.
What that's going to look like, as with AMD's own Smart Access Memory, is going to be a compatible version of Nvidia's graphics driver, but it's also going to need a compatible BIOS update for whichever motherboard you're running. As such Nvidia is going to have to be working with both AMD and Intel to get this going; chatting up Intel surely won't be an issue, but I'd love to be a fly on the wall as Nvidia talks to AMD about it.
