The version shot in the video is powered by a single Nvidia Titan X, which is the latest and greatest consumer-level GPU. The version they demonstrated at various events was instead powered by the $550 GTX 980, and it can reportedly run decently even on older cards. So the hardware isn't anything out of the ordinary at least for diehard gamers.
Having said that, the major pet-peeve I have with Epic is that they have a history of showing off breathtaking tech demos, but rarely publish the actual EXEs for others to play and stress test on their own hardware. I'm still waiting for the Samaritan binary from several years ago, don't think they ever released it. Not that I have doubts over its capabilities but I much prefer running them on my own rig than watching a compressed YouTube video of it.
