Civilization VII recommends 16 cores and 32GB RAM for 4K gameplay
However, the CPU and GPU requirements do seem a bit more reasonable.
As an aside, Firaxis also mentioned that Civ VII would be coming to Mac OS X, Linux, and even SteamOS—likely meaning a natively playable Steam Deck port down the line since that device is only 720p/800p. For a playable experience targeting 1080p, Low settings, and 30 FPS, Firaxis recommends entry-level CPUs from Intel 10th Gen and AMD Ryzen's first generation— very old processors at this point that most PC gamers have likely long upgraded past. While large-scale RTS and city/society building games can get pretty intense with simulated aspects tied to the CPU and memory bandwidth, it still seems a bit surprising for many users reacting in shock about how high the requirements for Civilization VI at 4K 60 FPS have become.
